4 OUR
As described in the entry WE, the 3rd person pl. pronouns distinguish plural forms from dual (depending on whether two or more persons are involved) and exclusive forms from inclusive (depending on whether the party addressed is included in “we/our”). Tolkien revised the relevant endings repeatedly. According to one late resolution described in VT49:16, the endings for exclusive “our” are –lma in the plural and –mma as a dual form, hence *aldalma “our tree” (with an “our” of at least three persons, not including the party addressed), but *aldamma “our tree = my and one other person’s tree”. The corresponding inclusive forms are –lwa (plural) and –ngwa (dual). Since the subject ending corresponding to the former is attested as “-lwe, –lve” (VT49:51), –lwa can surely also appear as *-lva, as in *omentielva “our meeting” (attested in the genitive case: omentielvo “of our meeting”, WJ:367). Hence *aldalwa/aldalva “our tree” (an “our” of at least three persons, including the party addressed), dual *aldangwa “our tree = thy and my tree”. – An independent word for plural exclusive "our" appears in VT43:19, 35: menya (also menyë modifying a plural noun). The corresponding plural inclusive form should apparently be *venya (pl. *venyë) for archaic *wenya (pl. wenyai > wenyë). The dual forms would most likely be *mentya (excl.) and *ventya (incl.); compare me, we/ve as the independent pronouns for “we” (with dual forms met, wet/*vet and dative forms *ment, * went/vent, from which the independent possessive pronouns are apparently derived by adding the adjectival ending -ya). – Notice that in an earlier conceptual phase, the forms in –mm- were plural (not as later dual) inclusive, and the forms in –lm- were plural inclusive rather than exclusive. This is why the word translated “of our meeting” appeared as omentielmo in the first edition of LotR, but was changed to omentielvo in the Second Edition. Cf. also Átaremma “our Father” as the first word of Tolkien’s translation of the Lord’s Prayer (VT43:12); this “our” is obviously meant to be plural exclusive rather than dual as it later became (according to Tolkien’s later conventions, “our Father” would be *Átarelma when a group of three or more persons addresses a party not included in “our”, in this case the Father himself). -

7 THEY, THEM
(3rd person pl. and dual forms): As the pronominal ending for “they”, Tolkien hesitated between -ltë and -ntë. For instance, a verb like “they do” is attested both as cariltë and carintë (VT49:16, 17). In one text, the ending -ltë is marked as archaic or poetic (VT49:17), but in other paradigms no such qualification occurs (VT49:51). The alternative form -nte- occurs in UT:317, with a second pronominal marker (-s “it”, denoting the object) following: Tiruvantes "they will keep it". General considerations of euphony may favour -ltë rather than -ntë (e.g. *quenteltë rather than *quententë for “they spoke” – in the past tense, many verbs end in -ntë even before any pronominal endings are supplied, like quentë “spoke” in this example). The ending -ltë (unlike -ntë) would also conform with the general system that the plural pronominal endings include the plural marker l (VT48:11). – In Tolkien’s early material, the ending -ltë appears as -lto instead (e.g. tulielto “they have come”, LT1:270). – A simple plural verb (with ending -r) can have “they” as its implied subject, as in the example quetir en “they still say” (PE17:167). – In the independent pronouns, distinct forms of may be used depending on whether “they, them” refers to living beings (persons, animals or even plants) or to non-living things or abstracts. The “personal” independent pronoun is te, which may have a long vowel when stressed (té, VT49:51). It is also attested in object position (laita te “bless them”, LotR:989 cf. Letters:308, VT43:20). It can receive case endings, e.g. dative ten (VT49:14; variant forms téna and tien, VT49:14, VT43:12, 21). As the “impersonal” they, them referring to non-living things, Tolkien in some sources used ta (VT43:20; 8, 9), but this apparently caused dissatisfaction because he also wanted ta to be the singular pronoun “that, it”. According to VT49:32, the form tai was introduced as the word for impersonal or inanimate “they, them” (in some places changed to te, apparently suggesting that Tolkien considered using te for both personal and impersonal “they/them”, abandoning the distinction). Another source (VT49:51) lists sa as the pl. impersonal form, but all other published sources use this pronoun for singular impersonal “it”, not pl. “they”. – The object “them” can also be expressed by the ending -t following another pronominal suffix (laituvalmet, “we shall bless [or praise] them", LotR:989 cf Letters:308). Presumably this ending -t makes no distinction between personal and impersonal forms. – Quenya also possesses special dual forms of “they, them”, used where only two persons or things are referred to (none of these pronouns distinguish between personal and impersonal forms). In VT49:16, the old ending for dual “they” is given as -stë (marked as archaic or poetic), but this would clash with the corresponding 2nd person ending. According to VT49:51, this ending was changed (also within the imaginary world) from -stë to -ttë, which seems the better alternative (*carittë, “the two of them do”). The independent dual pronoun is given as tú (ibid.) However, it may also be permissible to use te for “they, them” even where only two persons are involved (te is seemingly used with reference to Frodo and Sam in one of the examples above, laita te “bless them”). – Genitive forms, see THEIR; reflexive pronoun, see THEMSELVES. -
8 WE, US
The relevant Quenya pronouns make two distinctions not found in English. “We” can be either inclusive or exclusive, depending on whether the party addressed is included in “we” or not. Furthermore, “we” can be either plural (involving at least three persons) or dual (involving only two persons, the speaker and one other). Tolkien repeatedly revised the relevant endings. According to VT49:16, 51 one late resolution goes like this: The ending for plural exclusive “we” is -lmë, corresponding to dual exclusive -mmë. Hence e.g. carilmë *“we [not including you] do”, carimmë *“the two of us do; I and one other [not you] do”. The ending for plural inclusive “we” is to be -lwë or -lvë, corresponding to -ngwë for dual inclusive “we” (VT49:16; variant -nquë in VT49:51): Carilwë “we [including you] do”, caringwë “the two of us do; thou and I do”. The corresponding independent pronouns were pl. exclusive me, pl. inclusive we or later ve with variant vi (PE17:130); when stressed these could have long vowels (mé and wé > vé, VT49:51). They may also appear in object position (“us” rather than “we”), e.g. suffixed to ála “do not” in the negative command álamë tulya, "do not lead us" (VT43:12, 22). If these pronouns are to be dual, they receive the dual ending -t (exclusive met, inclusive wet > *vet; compare imbë met “between us [two]” in Namarië). The dual pronouns do not have a long vowel even when stressed. The pronouns me, we/*ve and their long variants can also receive case endings, like dative men or véna “for us” (VT43:27, 28, 33, VT49:14) or locative messë "on us" (VT44:12). An emphatic pronoun is attested as emmë “we” (VT43:20), this reflects an earlier conceptual stage where Tolkien used the forms in -mmë for plural rather than dual exclusive “we” (VT49:48, cf. forms like vammë, WJ:371); presumably he would later regard emmë as a dual exclusive form, corresponding to pl. *elmë (and with *elwë > *elvë and *engwë as the emphatic pronouns for inclusive “you”, plural and dual, respectively). These emphatic pronouns can also receive case endings; the dative form emmen “for us” is attested (VT43:12, 20). – Genitive forms, see OUR; reflexive pronouns, see OURSELVES. -
9 Usage note : you
In English you is used to address everybody, whereas French has two forms: tu and vous. The usual word to use when you are speaking to anyone you do not know very well is vous. This is sometimes called the polite form and is used for the subject, object, indirect object and emphatic pronoun:would you like some coffee?= voulez-vous du café?can I help you?= est-ce que je peux vous aider?what can I do for you?= qu’est-ce que je peux faire pour vous?The more informal pronoun tu is used between close friends and family members, within groups of children and young people, by adults when talking to children and always when talking to animals ; tu is the subject form, the direct and indirect object form is te (t’ before a vowel) and the form for emphatic use or use after a preposition is toi:would you like some coffee?= veux-tu du café?can I help you?= est-ce que je peux t’aider?there’s a letter for you= il y a une lettre pour toiAs a general rule, when talking to a French person use vous, wait to see how they address you and follow suit. It is safer to wait for the French person to suggest using tu. The suggestion will usually be phrased as on se tutoie? or on peut se tutoyer?Note that tu is only a singular pronoun and vous is the plural form of tu.Remember that in French the object and indirect object pronouns are always placed before the verb:she knows you= elle vous connaît or elle te connaîtIn compound tenses like the present perfect and the past perfect, the past participle agrees in number and gender with the direct object:I saw you on Saturday(to one male: polite form)= je vous ai vu samedi(to one female: polite form)= je vous ai vue samedi(to one male: informal form)= je t’ai vu samedi(to one female: informal form)= je t’ai vue samedi(to two or more people, male or mixed)= je vous ai vus samedi(to two or more females)= je vous ai vues samediWhen you is used impersonally as the more informal form of one, it is translated by on for the subject form and by vous or te for the object form, depending on whether the comment is being made amongst friends or in a more formal context:you can do as you like here= on peut faire ce qu’on veut icithese mushrooms can make you ill= ces champignons peuvent vous rendre malade or ces champignons peuvent te rendre maladeyou could easily lose your bag here= on pourrait facilement perdre son sac iciNote that your used with on is translated by son/sa/ses according to the gender and number of the noun that follows.For verb forms with vous, tu and on see the French verb tables.For particular usages see the entry you. -

Data Centers are a hot topic these days. No matter where you look, this once obscure aspect of infrastructure is getting a lot of attention. For years, there have been cost pressures on IT operations and this, when the need for modern capacity is greater than ever, has thrust data centers into the spotlight. Server and rack density continues to rise, placing DC professionals and businesses in tighter and tougher situations while they struggle to manage their IT environments. And now hyper-scale cloud infrastructure is taking traditional technologies to limits never explored before and focusing the imagination of the IT industry on new possibilities.
В настоящее время центры обработки данных являются широко обсуждаемой темой. Куда ни посмотришь, этот некогда малоизвестный аспект инфраструктуры привлекает все больше внимания. Годами ИТ-отделы испытывали нехватку средств и это выдвинуло ЦОДы в центр внимания, в то время, когда необходимость в современных ЦОДах стала как никогда высокой. Плотность серверов и стоек продолжают расти, все больше усложняя ситуацию для специалистов в области охлаждения и организаций в их попытках управлять своими ИТ-средами. И теперь гипермасштабируемая облачная инфраструктура подвергает традиционные технологии невиданным ранее нагрузкам, и заставляет ИТ-индустрию искать новые возможности.
At Microsoft, we have focused a lot of thought and research around how to best operate and maintain our global infrastructure and we want to share those learnings. While obviously there are some aspects that we keep to ourselves, we have shared how we operate facilities daily, our technologies and methodologies, and, most importantly, how we monitor and manage our facilities. Whether it’s speaking at industry events, inviting customers to our “Microsoft data center conferences” held in our data centers, or through other media like blogging and white papers, we believe sharing best practices is paramount and will drive the industry forward. So in that vein, we have some interesting news to share.
В компании MicroSoft уделяют большое внимание изучению наилучших методов эксплуатации и технического обслуживания своей глобальной инфраструктуры и делятся результатами своих исследований. И хотя мы, конечно, не раскрываем некоторые аспекты своих исследований, мы делимся повседневным опытом эксплуатации дата-центров, своими технологиями и методологиями и, что важнее всего, методами контроля и управления своими объектами. Будь то доклады на отраслевых событиях, приглашение клиентов на наши конференции, которые посвящены центрам обработки данных MicroSoft, и проводятся в этих самых дата-центрах, или использование других средств, например, блоги и спецификации, мы уверены, что обмен передовым опытом имеет первостепенное значение и будет продвигать отрасль вперед.
Today we are sharing our Generation 4 Modular Data Center plan. This is our vision and will be the foundation of our cloud data center infrastructure in the next five years. We believe it is one of the most revolutionary changes to happen to data centers in the last 30 years. Joining me, in writing this blog are Daniel Costello, my director of Data Center Research and Engineering and Christian Belady, principal power and cooling architect. I feel their voices will add significant value to driving understanding around the many benefits included in this new design paradigm.
Сейчас мы хотим поделиться своим планом модульного дата-центра четвертого поколения. Это наше видение и оно будет основанием для инфраструктуры наших облачных дата-центров в ближайшие пять лет. Мы считаем, что это одно из самых революционных изменений в дата-центрах за последние 30 лет. Вместе со мной в написании этого блога участвовали Дэниел Костелло, директор по исследованиям и инжинирингу дата-центров, и Кристиан Белади, главный архитектор систем энергоснабжения и охлаждения. Мне кажется, что их авторитет придаст больше веса большому количеству преимуществ, включенных в эту новую парадигму проектирования.
Our “Gen 4” modular data centers will take the flexibility of containerized servers—like those in our Chicago data center—and apply it across the entire facility. So what do we mean by modular? Think of it like “building blocks”, where the data center will be composed of modular units of prefabricated mechanical, electrical, security components, etc., in addition to containerized servers.
Was there a key driver for the Generation 4 Data Center?Наши модульные дата-центры “Gen 4” будут гибкими с контейнерами серверов – как серверы в нашем чикагском дата-центре. И гибкость будет применяться ко всему ЦОД. Итак, что мы подразумеваем под модульностью? Мы думаем о ней как о “строительных блоках”, где дата-центр будет состоять из модульных блоков изготовленных в заводских условиях электрических систем и систем охлаждения, а также систем безопасности и т.п., в дополнение к контейнеризованным серверам.
Был ли ключевой стимул для разработки дата-центра четвертого поколения?
If we were to summarize the promise of our Gen 4 design into a single sentence it would be something like this: “A highly modular, scalable, efficient, just-in-time data center capacity program that can be delivered anywhere in the world very quickly and cheaply, while allowing for continued growth as required.” Sounds too good to be true, doesn’t it? Well, keep in mind that these concepts have been in initial development and prototyping for over a year and are based on cumulative knowledge of previous facility generations and the advances we have made since we began our investments in earnest on this new design.Если бы нам нужно было обобщить достоинства нашего проекта Gen 4 в одном предложении, это выглядело бы следующим образом: “Центр обработки данных с высоким уровнем модульности, расширяемости, и энергетической эффективности, а также возможностью постоянного расширения, в случае необходимости, который можно очень быстро и дешево развертывать в любом месте мира”. Звучит слишком хорошо для того чтобы быть правдой, не так ли? Ну, не забывайте, что эти концепции находились в процессе начальной разработки и создания опытного образца в течение более одного года и основываются на опыте, накопленном в ходе развития предыдущих поколений ЦОД, а также успехах, сделанных нами со времени, когда мы начали вкладывать серьезные средства в этот новый проект.
One of the biggest challenges we’ve had at Microsoft is something Mike likes to call the ‘Goldilock’s Problem’. In a nutshell, the problem can be stated as:
The worst thing we can do in delivering facilities for the business is not have enough capacity online, thus limiting the growth of our products and services.Одну из самых больших проблем, с которыми приходилось сталкиваться Майкрософт, Майк любит называть ‘Проблемой Лютика’. Вкратце, эту проблему можно выразить следующим образом:
Самое худшее, что может быть при строительстве ЦОД для бизнеса, это не располагать достаточными производственными мощностями, и тем самым ограничивать рост наших продуктов и сервисов.The second worst thing we can do in delivering facilities for the business is to have too much capacity online.
А вторым самым худшим моментом в этой сфере может слишком большое количество производственных мощностей.
This has led to a focus on smart, intelligent growth for the business — refining our overall demand picture. It can’t be too hot. It can’t be too cold. It has to be ‘Just Right!’ The capital dollars of investment are too large to make without long term planning. As we struggled to master these interesting challenges, we had to ensure that our technological plan also included solutions for the business and operational challenges we faced as well.
So let’s take a high level look at our Generation 4 designЭто заставило нас сосредоточиваться на интеллектуальном росте для бизнеса — refining our overall demand picture. Это не должно быть слишком горячим. И это не должно быть слишком холодным. Это должно быть ‘как раз, таким как надо!’ Нельзя делать такие большие капиталовложения без долгосрочного планирования. Пока мы старались решить эти интересные проблемы, мы должны были гарантировать, что наш технологический план будет также включать решения для коммерческих и эксплуатационных проблем, с которыми нам также приходилось сталкиваться.
Давайте рассмотрим наш проект дата-центра четвертого поколенияAre you ready for some great visuals? Check out this video at Soapbox. Click here for the Microsoft 4th Gen Video.
It’s a concept video that came out of my Data Center Research and Engineering team, under Daniel Costello, that will give you a view into what we think is the future.
From a configuration, construct-ability and time to market perspective, our primary goals and objectives are to modularize the whole data center. Not just the server side (like the Chicago facility), but the mechanical and electrical space as well. This means using the same kind of parts in pre-manufactured modules, the ability to use containers, skids, or rack-based deployments and the ability to tailor the Redundancy and Reliability requirements to the application at a very specific level.

Это концептуальное видео, созданное командой отдела Data Center Research and Engineering, возглавляемого Дэниелом Костелло, которое даст вам наше представление о будущем.
С точки зрения конфигурации, строительной технологичности и времени вывода на рынок, нашими главными целями и задачами агрегатирование всего дата-центра. Не только серверную часть, как дата-центр в Чикаго, но также системы охлаждения и электрические системы. Это означает применение деталей одного типа в сборных модулях, возможность использования контейнеров, салазок, или стоечных систем, а также возможность подстраивать требования избыточности и надежности для данного приложения на очень специфичном уровне.Our goals from a cost perspective were simple in concept but tough to deliver. First and foremost, we had to reduce the capital cost per critical Mega Watt by the class of use. Some applications can run with N-level redundancy in the infrastructure, others require a little more infrastructure for support. These different classes of infrastructure requirements meant that optimizing for all cost classes was paramount. At Microsoft, we are not a one trick pony and have many Online products and services (240+) that require different levels of operational support. We understand that and ensured that we addressed it in our design which will allow us to reduce capital costs by 20%-40% or greater depending upon class.
Нашими целями в области затрат были концептуально простыми, но трудно реализуемыми. В первую очередь мы должны были снизить капитальные затраты в пересчете на один мегаватт, в зависимости от класса резервирования. Некоторые приложения могут вполне работать на базе инфраструктуры с резервированием на уровне N, то есть без резервирования, а для работы других приложений требуется больше инфраструктуры. Эти разные классы требований инфраструктуры подразумевали, что оптимизация всех классов затрат имеет преобладающее значение. В Майкрософт мы не ограничиваемся одним решением и располагаем большим количеством интерактивных продуктов и сервисов (240+), которым требуются разные уровни эксплуатационной поддержки. Мы понимаем это, и учитываем это в своем проекте, который позволит нам сокращать капитальные затраты на 20%-40% или более в зависимости от класса.For example, non-critical or geo redundant applications have low hardware reliability requirements on a location basis. As a result, Gen 4 can be configured to provide stripped down, low-cost infrastructure with little or no redundancy and/or temperature control. Let’s say an Online service team decides that due to the dramatically lower cost, they will simply use uncontrolled outside air with temperatures ranging 10-35 C and 20-80% RH. The reality is we are already spec-ing this for all of our servers today and working with server vendors to broaden that range even further as Gen 4 becomes a reality. For this class of infrastructure, we eliminate generators, chillers, UPSs, and possibly lower costs relative to traditional infrastructure.
Например, некритичные или гео-избыточные системы имеют низкие требования к аппаратной надежности на основе местоположения. В результате этого, Gen 4 можно конфигурировать для упрощенной, недорогой инфраструктуры с низким уровнем (или вообще без резервирования) резервирования и / или температурного контроля. Скажем, команда интерактивного сервиса решает, что, в связи с намного меньшими затратами, они будут просто использовать некондиционированный наружный воздух с температурой 10-35°C и влажностью 20-80% RH. В реальности мы уже сегодня предъявляем эти требования к своим серверам и работаем с поставщиками серверов над еще большим расширением диапазона температур, так как наш модуль и подход Gen 4 становится реальностью. Для подобного класса инфраструктуры мы удаляем генераторы, чиллеры, ИБП, и, возможно, будем предлагать более низкие затраты, по сравнению с традиционной инфраструктурой.
Applications that demand higher level of redundancy or temperature control will use configurations of Gen 4 to meet those needs, however, they will also cost more (but still less than traditional data centers). We see this cost difference driving engineering behavioral change in that we predict more applications will drive towards Geo redundancy to lower costs.
Системы, которым требуется более высокий уровень резервирования или температурного контроля, будут использовать конфигурации Gen 4, отвечающие этим требованиям, однако, они будут также стоить больше. Но все равно они будут стоить меньше, чем традиционные дата-центры. Мы предвидим, что эти различия в затратах будут вызывать изменения в методах инжиниринга, и по нашим прогнозам, это будет выражаться в переходе все большего числа систем на гео-избыточность и меньшие затраты.
Another cool thing about Gen 4 is that it allows us to deploy capacity when our demand dictates it. Once finalized, we will no longer need to make large upfront investments. Imagine driving capital costs more closely in-line with actual demand, thus greatly reducing time-to-market and adding the capacity Online inherent in the design. Also reduced is the amount of construction labor required to put these “building blocks” together. Since the entire platform requires pre-manufacture of its core components, on-site construction costs are lowered. This allows us to maximize our return on invested capital.
Еще одно достоинство Gen 4 состоит в том, что он позволяет нам разворачивать дополнительные мощности, когда нам это необходимо. Как только мы закончим проект, нам больше не нужно будет делать большие начальные капиталовложения. Представьте себе возможность более точного согласования капитальных затрат с реальными требованиями, и тем самым значительного снижения времени вывода на рынок и интерактивного добавления мощностей, предусматриваемого проектом. Также снижен объем строительных работ, требуемых для сборки этих “строительных блоков”. Поскольку вся платформа требует предварительного изготовления ее базовых компонентов, затраты на сборку также снижены. Это позволит нам увеличить до максимума окупаемость своих капиталовложений.
Мы все подвергаем сомнениюIn our design process, we questioned everything. You may notice there is no roof and some might be uncomfortable with this. We explored the need of one and throughout our research we got some surprising (positive) results that showed one wasn’t needed.
В своем процессе проектирования мы все подвергаем сомнению. Вы, наверное, обратили внимание на отсутствие крыши, и некоторым специалистам это могло не понравиться. Мы изучили необходимость в крыше и в ходе своих исследований получили удивительные результаты, которые показали, что крыша не нужна.
Серийное производство дата центров
In short, we are striving to bring Henry Ford’s Model T factory to the data center. http://en.wikipedia.org/wiki/Henry_Ford#Model_T. Gen 4 will move data centers from a custom design and build model to a commoditized manufacturing approach. We intend to have our components built in factories and then assemble them in one location (the data center site) very quickly. Think about how a computer, car or plane is built today. Components are manufactured by different companies all over the world to a predefined spec and then integrated in one location based on demands and feature requirements. And just like Henry Ford’s assembly line drove the cost of building and the time-to-market down dramatically for the automobile industry, we expect Gen 4 to do the same for data centers. Everything will be pre-manufactured and assembled on the pad.Мы хотим применить модель автомобильной фабрики Генри Форда к дата-центру. Проект Gen 4 будет способствовать переходу от модели специализированного проектирования и строительства к товарно-производственному, серийному подходу. Мы намерены изготавливать свои компоненты на заводах, а затем очень быстро собирать их в одном месте, в месте строительства дата-центра. Подумайте о том, как сегодня изготавливается компьютер, автомобиль или самолет. Компоненты изготавливаются по заранее определенным спецификациям разными компаниями во всем мире, затем собираются в одном месте на основе спроса и требуемых характеристик. И точно так же как сборочный конвейер Генри Форда привел к значительному уменьшению затрат на производство и времени вывода на рынок в автомобильной промышленности, мы надеемся, что Gen 4 сделает то же самое для дата-центров. Все будет предварительно изготавливаться и собираться на месте.
Невероятно энергоэффективный ЦОД
And did we mention that this platform will be, overall, incredibly energy efficient? From a total energy perspective not only will we have remarkable PUE values, but the total cost of energy going into the facility will be greatly reduced as well. How much energy goes into making concrete? Will we need as much of it? How much energy goes into the fuel of the construction vehicles? This will also be greatly reduced! A key driver is our goal to achieve an average PUE at or below 1.125 by 2012 across our data centers. More than that, we are on a mission to reduce the overall amount of copper and water used in these facilities. We believe these will be the next areas of industry attention when and if the energy problem is solved. So we are asking today…“how can we build a data center with less building”?А мы упоминали, что эта платформа будет, в общем, невероятно энергоэффективной? С точки зрения общей энергии, мы получим не только поразительные значения PUE, но общая стоимость энергии, затраченной на объект будет также значительно снижена. Сколько энергии идет на производство бетона? Нам нужно будет столько энергии? Сколько энергии идет на питание инженерных строительных машин? Это тоже будет значительно снижено! Главным стимулом является достижение среднего PUE не больше 1.125 для всех наших дата-центров к 2012 году. Более того, у нас есть задача сокращения общего количества меди и воды в дата-центрах. Мы думаем, что эти задачи станут следующей заботой отрасли после того как будет решена энергетическая проблема. Итак, сегодня мы спрашиваем себя…“как можно построить дата-центр с меньшим объемом строительных работ”?
Строительство дата центров без чиллеровWe have talked openly and publicly about building chiller-less data centers and running our facilities using aggressive outside economization. Our sincerest hope is that Gen 4 will completely eliminate the use of water. Today’s data centers use massive amounts of water and we see water as the next scarce resource and have decided to take a proactive stance on making water conservation part of our plan.
Мы открыто и публично говорили о строительстве дата-центров без чиллеров и активном использовании в наших центрах обработки данных технологий свободного охлаждения или фрикулинга. Мы искренне надеемся, что Gen 4 позволит полностью отказаться от использования воды. Современные дата-центры расходуют большие объемы воды и так как мы считаем воду следующим редким ресурсом, мы решили принять упреждающие меры и включить экономию воды в свой план.
By sharing this with the industry, we believe everyone can benefit from our methodology. While this concept and approach may be intimidating (or downright frightening) to some in the industry, disclosure ultimately is better for all of us.
Делясь этим опытом с отраслью, мы считаем, что каждый сможет извлечь выгоду из нашей методологией. Хотя эта концепция и подход могут показаться пугающими (или откровенно страшными) для некоторых отраслевых специалистов, раскрывая свои планы мы, в конечном счете, делаем лучше для всех нас.
Gen 4 design (even more than just containers), could reduce the ‘religious’ debates in our industry. With the central spine infrastructure in place, containers or pre-manufactured server halls can be either AC or DC, air-side economized or water-side economized, or not economized at all (though the sanity of that might be questioned). Gen 4 will allow us to decommission, repair and upgrade quickly because everything is modular. No longer will we be governed by the initial decisions made when constructing the facility. We will have almost unlimited use and re-use of the facility and site. We will also be able to use power in an ultra-fluid fashion moving load from critical to non-critical as use and capacity requirements dictate.
Проект Gen 4 позволит уменьшить ‘религиозные’ споры в нашей отрасли. Располагая базовой инфраструктурой, контейнеры или сборные серверные могут оборудоваться системами переменного или постоянного тока, воздушными или водяными экономайзерами, или вообще не использовать экономайзеры. Хотя можно подвергать сомнению разумность такого решения. Gen 4 позволит нам быстро выполнять работы по выводу из эксплуатации, ремонту и модернизации, поскольку все будет модульным. Мы больше не будем руководствоваться начальными решениями, принятыми во время строительства дата-центра. Мы сможем использовать этот дата-центр и инфраструктуру в течение почти неограниченного периода времени. Мы также сможем применять сверхгибкие методы использования электрической энергии, переводя оборудование в режимы критической или некритической нагрузки в соответствии с требуемой мощностью.
Gen 4 – это стандартная платформаFinally, we believe this is a big game changer. Gen 4 will provide a standard platform that our industry can innovate around. For example, all modules in our Gen 4 will have common interfaces clearly defined by our specs and any vendor that meets these specifications will be able to plug into our infrastructure. Whether you are a computer vendor, UPS vendor, generator vendor, etc., you will be able to plug and play into our infrastructure. This means we can also source anyone, anywhere on the globe to minimize costs and maximize performance. We want to help motivate the industry to further innovate—with innovations from which everyone can reap the benefits.
Наконец, мы уверены, что это будет фактором, который значительно изменит ситуацию. Gen 4 будет представлять собой стандартную платформу, которую отрасль сможет обновлять. Например, все модули в нашем Gen 4 будут иметь общепринятые интерфейсы, четко определяемые нашими спецификациями, и оборудование любого поставщика, которое отвечает этим спецификациям можно будет включать в нашу инфраструктуру. Независимо от того производите вы компьютеры, ИБП, генераторы и т.п., вы сможете включать свое оборудование нашу инфраструктуру. Это означает, что мы также сможем обеспечивать всех, в любом месте земного шара, тем самым сводя до минимума затраты и максимальной увеличивая производительность. Мы хотим создать в отрасли мотивацию для дальнейших инноваций – инноваций, от которых каждый сможет получать выгоду.

Мы надеемся, что вы присоединитесь к нам в этом невероятном путешествии по миру изменений и инноваций!
На этот проект уже потрачены долгие часы исследований и проектирования. И еще предстоит потратить много дней и ночей, но мы имеем четкое представление о конечной цели. Однако будьте уверены, что как только мы доведем до конца проект модульного дата-центра четвертого поколения, мы вскоре начнем думать о проекте дата-центра пятого поколения. Всегда есть возможность для улучшений.So if you happen to come across Goldilocks in the forest, and you are curious as to why she is smiling you will know that she feels very good about getting very close to ‘JUST RIGHT’.
Generations of Evolution – some background on our data center designsТак что, если вы встретите в лесу девочку по имени Лютик, и вам станет любопытно, почему она улыбается, вы будете знать, что она очень довольна тем, что очень близко подошла к ‘ОПИМАЛЬНОМУ РЕШЕНИЮ’.
Поколения эволюции – история развития наших дата-центровWe thought you might be interested in understanding what happened in the first three generations of our data center designs. When Ray Ozzie wrote his Software plus Services memo it posed a very interesting challenge to us. The winds of change were at ‘tornado’ proportions. That “plus Services” tag had some significant (and unstated) challenges inherent to it. The first was that Microsoft was going to evolve even further into an operations company. While we had been running large scale Internet services since 1995, this development lead us to an entirely new level. Additionally, these “services” would span across both Internet and Enterprise businesses. To those of you who have to operate “stuff”, you know that these are two very different worlds in operational models and challenges. It also meant that, to achieve the same level of reliability and performance required our infrastructure was going to have to scale globally and in a significant way.
Мы подумали, что может быть вам будет интересно узнать историю первых трех поколений наших центров обработки данных. Когда Рэй Оззи написал свою памятную записку Software plus Services, он поставил перед нами очень интересную задачу. Ветра перемен двигались с ураганной скоростью. Это окончание “plus Services” скрывало в себе какие-то значительные и неопределенные задачи. Первая заключалась в том, что Майкрософт собиралась в еще большей степени стать операционной компанией. Несмотря на то, что мы управляли большими интернет-сервисами, начиная с 1995 г., эта разработка подняла нас на абсолютно новый уровень. Кроме того, эти “сервисы” охватывали интернет-компании и корпорации. Тем, кому приходится всем этим управлять, известно, что есть два очень разных мира в области операционных моделей и задач. Это также означало, что для достижения такого же уровня надежности и производительности требовалось, чтобы наша инфраструктура располагала значительными возможностями расширения в глобальных масштабах.
It was that intense atmosphere of change that we first started re-evaluating data center technology and processes in general and our ideas began to reach farther than what was accepted by the industry at large. This was the era of Generation 1. As we look at where most of the world’s data centers are today (and where our facilities were), it represented all the known learning and design requirements that had been in place since IBM built the first purpose-built computer room. These facilities focused more around uptime, reliability and redundancy. Big infrastructure was held accountable to solve all potential environmental shortfalls. This is where the majority of infrastructure in the industry still is today.
Именно в этой атмосфере серьезных изменений мы впервые начали переоценку ЦОД-технологий и технологий вообще, и наши идеи начали выходить за пределы общепринятых в отрасли представлений. Это была эпоха ЦОД первого поколения. Когда мы узнали, где сегодня располагается большинство мировых дата-центров и где находятся наши предприятия, это представляло весь опыт и навыки проектирования, накопленные со времени, когда IBM построила первую серверную. В этих ЦОД больше внимания уделялось бесперебойной работе, надежности и резервированию. Большая инфраструктура была призвана решать все потенциальные экологические проблемы. Сегодня большая часть инфраструктуры все еще находится на этом этапе своего развития.
We soon realized that traditional data centers were quickly becoming outdated. They were not keeping up with the demands of what was happening technologically and environmentally. That’s when we kicked off our Generation 2 design. Gen 2 facilities started taking into account sustainability, energy efficiency, and really looking at the total cost of energy and operations.
Очень быстро мы поняли, что стандартные дата-центры очень быстро становятся устаревшими. Они не поспевали за темпами изменений технологических и экологических требований. Именно тогда мы стали разрабатывать ЦОД второго поколения. В этих дата-центрах Gen 2 стали принимать во внимание такие факторы как устойчивое развитие, энергетическая эффективность, а также общие энергетические и эксплуатационные.
No longer did we view data centers just for the upfront capital costs, but we took a hard look at the facility over the course of its life. Our Quincy, Washington and San Antonio, Texas facilities are examples of our Gen 2 data centers where we explored and implemented new ways to lessen the impact on the environment. These facilities are considered two leading industry examples, based on their energy efficiency and ability to run and operate at new levels of scale and performance by leveraging clean hydro power (Quincy) and recycled waste water (San Antonio) to cool the facility during peak cooling months.
Мы больше не рассматривали дата-центры только с точки зрения начальных капитальных затрат, а внимательно следили за работой ЦОД на протяжении его срока службы. Наши объекты в Куинси, Вашингтоне, и Сан-Антонио, Техас, являются образцами наших ЦОД второго поколения, в которых мы изучали и применяли на практике новые способы снижения воздействия на окружающую среду. Эти объекты считаются двумя ведущими отраслевыми примерами, исходя из их энергетической эффективности и способности работать на новых уровнях производительности, основанных на использовании чистой энергии воды (Куинси) и рециклирования отработанной воды (Сан-Антонио) для охлаждения объекта в самых жарких месяцах.
As we were delivering our Gen 2 facilities into steel and concrete, our Generation 3 facilities were rapidly driving the evolution of the program. The key concepts for our Gen 3 design are increased modularity and greater concentration around energy efficiency and scale. The Gen 3 facility will be best represented by the Chicago, Illinois facility currently under construction. This facility will seem very foreign compared to the traditional data center concepts most of the industry is comfortable with. In fact, if you ever sit around in our container hanger in Chicago it will look incredibly different from a traditional raised-floor data center. We anticipate this modularization will drive huge efficiencies in terms of cost and operations for our business. We will also introduce significant changes in the environmental systems used to run our facilities. These concepts and processes (where applicable) will help us gain even greater efficiencies in our existing footprint, allowing us to further maximize infrastructure investments.
Так как наши ЦОД второго поколения строились из стали и бетона, наши центры обработки данных третьего поколения начали их быстро вытеснять. Главными концептуальными особенностями ЦОД третьего поколения Gen 3 являются повышенная модульность и большее внимание к энергетической эффективности и масштабированию. Дата-центры третьего поколения лучше всего представлены объектом, который в настоящее время строится в Чикаго, Иллинойс. Этот ЦОД будет выглядеть очень необычно, по сравнению с общепринятыми в отрасли представлениями о дата-центре. Действительно, если вам когда-либо удастся побывать в нашем контейнерном ангаре в Чикаго, он покажется вам совершенно непохожим на обычный дата-центр с фальшполом. Мы предполагаем, что этот модульный подход будет способствовать значительному повышению эффективности нашего бизнеса в отношении затрат и операций. Мы также внесем существенные изменения в климатические системы, используемые в наших ЦОД. Эти концепции и технологии, если применимо, позволят нам добиться еще большей эффективности наших существующих дата-центров, и тем самым еще больше увеличивать капиталовложения в инфраструктуру.
This is definitely a journey, not a destination industry. In fact, our Generation 4 design has been under heavy engineering for viability and cost for over a year. While the demand of our commercial growth required us to make investments as we grew, we treated each step in the learning as a process for further innovation in data centers. The design for our future Gen 4 facilities enabled us to make visionary advances that addressed the challenges of building, running, and operating facilities all in one concerted effort.
Это определенно путешествие, а не конечный пункт назначения. На самом деле, наш проект ЦОД четвертого поколения подвергался серьезным испытаниям на жизнеспособность и затраты на протяжении целого года. Хотя необходимость в коммерческом росте требовала от нас постоянных капиталовложений, мы рассматривали каждый этап своего развития как шаг к будущим инновациям в области дата-центров. Проект наших будущих ЦОД четвертого поколения Gen 4 позволил нам делать фантастические предположения, которые касались задач строительства, управления и эксплуатации объектов как единого упорядоченного процесса.

"Ser" or "estar"?
You can use "ser": ► when defining or identifying by linking two nouns or noun phrases:
Paris is the capital of France París es la capital de Francia
He was the most hated man in the village Era el hombre más odiado del pueblo ► to describe essential or inherent characteristics (e.g. colour, material, nationality, race, shape, size {etc}):
His mother is German Su madre es alemana
She was blonde Era rubia ► with most impersonal expressions not involving past participles:
It is important to be on time Es importante llegar a tiempo
Está claro que is an exception:
It is obvious you don't understand Está claro que no lo entiendes ► when telling the time or talking about time or age:
It is ten o'clock Son las diez
It's very late. Let's go home Es muy tarde. Vamos a casa
He lived in the country when he was young Vivió en el campo cuando era joven ► to indicate possession or duty:
It's mine Es mío
This is your responsibility Este asunto es responsabilidad tuya ► with events in the sense of "take place":
The 1992 Olympic Games were in Barcelona Los Juegos Olímpicos de 1992 fueron en Barcelona
"Where is the exam?" - "It's in Room 1" "¿Dónde es el examen?" - "Es en el Aula Número 1" NOTE: Compare this usage with that of estar (see below) to talk about location of places, objects and people.
You can use "estar": ► to talk about location of places, objects and people:
"Where is Zaragoza?" - "It's in Spain" "¿Dónde está Zaragoza?" - "Está en España"
Your glasses are on the bedside table Tus gafas están en la mesilla de noche NOTE: But use ser with events in the sense of "take place" (see above)}. ► to talk about changeable state, condition or mood:
The teacher is ill La profesora está enferma
The coffee's cold El café está frío
How happy I am! ¡Qué contento estoy! NOTE: Feliz, however, which is seen as more permanent than contento, is used mainly with ser. ► to form progressive tenses:
We're having lunch. Is it ok if I call you later? Estamos comiendo. Te llamaré luego, ¿vale?
Both "ser" and "estar" can be used with past participles ► Use ser in {passive} constructions:
This play was written by Lorca Esta obra fue escrita por Lorca
He was shot dead (by a terrorist group) Fue asesinado a tiros (por un grupo terrorista) NOTE: The passive is not used as often in Spanish as it is in English. ► Use estar with past participles to describe the {results} of a previous action or event:
We threw them away because they were broken Los tiramos a la basura porque estaban rotos
He's dead Está muerto ► Compare the use of ser + ((past participle)) which describes {action} and estar + ((past participle)) which describes {result} in the following:
The window was broken by the firemen La ventana fue rota por los bomberos
The window was broken La ventana estaba rota
It was painted around 1925 Fue pintado hacia 1925
The floor is painted a dark colour El suelo está pintado de color oscuro ► Ser and estar are both used in impersonal expressions with past participles. As above, the use of ser implies {action} while the use of estar implies {result}:
It is understood that the work was never finished Es sabido que el trabajo nunca se llegó a terminar
It is a proven fact that vaccinations save many lives Está demostrado que las vacunas salvan muchas vidas
"Ser" and "estar" with adjectives ► Some adjectives can be used with both ser and estar but the meaning changes completely depending on the verb:
He's clever Es listo
Are you ready? ¿Estás listo?
Chemistry is boring La química es aburrida
I'm bored Estoy aburrido ► Other adjectives can also be used with both verbs but the use of ser describes a {characteristic} while the use of estar implies a {change}:
He's very handsome Es muy guapo
You look great in that dress! Estás muy guapa con ese vestido
He's slim Es delgado
You're (looking) very slim ¡Estás muy delgada! For further uses and examples, see main entry* * *[biːˌ] weak form [bi]

Use usted/ ustedes with people who are older than you, those in authority and in formal contexts. ► In Latin America usage varies depending on the country and in some places only the usted forms are used. Where the tú form does exist, only use it with people you know very well. In other areas vos, used with verb forms that are similar to the vosotros ones, often replaces tú.

17 better
I.II.❢ When better is used as an adjective it is translated by meilleur or mieux depending on the context (see below, and note that meilleur is the comparative form of bon, mieux the comparative form of bien). The choice between meilleur and mieux in the construction to be better than depends on whether bon or bien would be used originally with the noun. Other constructions translate as follows: this is a better bag/car = ce sac/cette voiture est mieux ; it is better to do = il vaut mieux faire or il est mieux de faire. As an adverb, better can almost always be translated by mieux. For more examples and particular usages, see the entry below.A n1 (something preferable, more excellent) the better le/la meilleur/-e m/f ; much ou by far the better of the two de loin le/la meilleur/-e des deux ;2 ( more desirable state of affairs) to deserve/expect/hope for better mériter/attendre/espérer mieux ; so much the better, all the better tant mieux ; a change ou turn for the better une amélioration ; to change ou take a turn for the better s'améliorer ; the weather changed, and not for the better le temps a changé, et pas en mieux ;1 (more pleasing, satisfactory) [weather, day, news, joke, forecast, review, salary, price, range] meilleur ; [party, game, book, film, activity] mieux ; playing is better than watching jouer, c'est mieux que de regarder ; to get better s'améliorer ; the weather is no better le temps n'est pas meilleur or ne s'est pas amélioré ; things are getting better ça va mieux ; ‘good news?’-‘it couldn't be better!’ ‘bonnes nouvelles?’-‘on ne peut meilleures!’ ; to look/sound better être/sonner mieux ; to taste/smell better être/sentir meilleur, avoir un/-e meilleur/-e goût/odeur ; it would taste all the better for some salt ce serait meilleur avec du sel ; it looked all the better for it cela n'en était que mieux ; that's better! voilà qui est mieux! ;2 (well, recovered) to be better [patient, cold, headache] aller mieux ; to feel all the better for se sentir mieux après [rest, meal] ; better than I/it was mieux qu'avant ;3 ( happier) [mood] meilleur ; to feel better se sentir mieux ; I'd feel better if you did/didn't do je me sentirais mieux si tu faisais/ne faisais pas ; if it makes you feel any better ( less worried or awkward) si ça t'aide à te sentir mieux ; ( less sad) si ça peut te consoler ; to feel better about doing ( less nervous) se sentir à même de faire ; (less worried, guilty) avoir moins de scrupules à faire ;4 (of superior quality, class) [food, result, film, book, quality] meilleur ; [car, carpet, district, family] mieux ; [land, school, hotel] meilleur, mieux ; [coat, shoes, furniture] de meilleure qualité ; one of the better schools une des meilleures écoles ; he went to a better school than I did ou than me il est allé dans une école meilleure que la mienne ;5 (more virtuous, commendable) [person] mieux ; [life, influence, nature] meilleur ; to be a better man/woman than être mieux que ; you're a better man than I am! tu es mieux que moi! ; to be no better than sb ne pas être mieux que qn ; to be no better than a thief être un voleur ni plus ni moins ;6 ( more skilled) [doctor, actor, teacher] meilleur ; to be a better poet than sb être meilleur poète que qn ; to be a better swimmer than sb nager mieux que qn ; to be a better singer than dancer chanter mieux que l'on ne danse ; to be a better father than husband être meilleur père que mari ; to be better at être meilleur en [subject, sport] ; to be better at doing faire mieux ; he's no better at driving than she is ou than her il ne conduit pas mieux qu'elle ;7 (more suitable, valid, appropriate) [tune, tool, way, word, idea, example, reason, excuse, choice] meilleur ; to be better for être meilleur pour [purpose, task] ; to be better for doing être mieux pour faire ; to be better than nothing être mieux que rien ; better a part-time job than no job mieux vaut un travail à mi-temps que pas de travail ; the bigger/sooner the better le plus grand/vite possible ; the faster you work the better plus tu travailles vite, mieux ça vaudra ; the less said about that the better mieux vaut ne pas parler de ça ; who better to play the part?

18 relevant costs/revenues
Fincosts and revenues appropriate to a specific management decision. These are represented by future cash flows whose magnitude will vary depending upon the outcome of the management decision made. If stock is sold by a retailer, the relevant cost, used in the determination of the profitability of the transaction, would be the cost of replacing the stock, not its original purchase price, which is a sunk cost. Abandonment analysis, based on relevant cost and revenues, is the process of determining whether or not it is more profitable to discontinue a product or service than to continue it. -

(continuous) current-carrying capacity
ampacity (US)
maximum value of electric current which can be carried continuously by a conductor, a device or an apparatus, under specified conditions without its steady-state temperature exceeding a specified value
[IEV number 826-11-13]
ampacity
The current in amperes that a conductor can carry continuously under the conditions of use without exceeding its temperature rating.
[National Electrical Cod]FR
courant (permanent) admissible, m
valeur maximale du courant électrique qui peut parcourir en permanence, un conducteur, un dispositif ou un appareil, sans que sa température de régime permanent, dans des conditions données, soit supérieure à la valeur spécifiée
[IEV number 826-11-13]Ampacity, the term is defined as the maximum amount of current a cable can carry before sustaining immediate or progressive deterioration. Also described as current rating or current-carrying capacity, is the RMS electric current which a device can continuously carry while remaining within its temperature rating. The ampacity of a cable depends on:
- its insulation temperature rating;
- conductor electrical properties for current;
- frequency, in the case of alternating currents;
- ability to dissipate heat, which depends on cable geometry and its surroundings;
- ambient temperature.
Electric wires have some resistance, and electric current flowing through them causes voltage drop and power dissipation, which heats the cable. Copper or aluminum can conduct a large amount of current before melting, but long before the conductors melt, their insulation would be damaged by the heat.
The ampacity for a power cable is thus based on physical and electrical properties of the material & construction of the conductor and of its insulation, ambient temperature, and environmental conditions adjacent to the cable. Having a large overall surface area may dissipate heat well if the environment can absorb the heat.
In a long run of cable, different conditions govern, and installation regulations normally specify that the most severe condition along the run governs the cable's rating. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. Derating is necessary for multiple circuits in close proximity. When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.
