1 volume bitmap
A stored reference (which may exist both on hierarchical directory volumes and in memory) to every piece of data that is in the allocation blocks and indicates whether the block is allocated or free for use. -
2 mirrored volume
"A fault-tolerant volume that duplicates data on two physical disks. A mirrored volume provides data redundancy by using two identical volumes, which are called mirrors, to duplicate the information contained on the volume. A mirror is always located on a different disk. If one of the physical disks fails, the data on the failed disk becomes unavailable, but the system continues to operate in the mirror on the remaining disk. You can create mirrored volumes only on dynamic disks on computers running the Windows 2000 Server or Windows Server 2003 families of operating systems. You cannot extend mirrored volumes." -
3 RAID-5 volume
"A fault-tolerant volume with data and parity striped intermittently across three or more physical disks. Parity is a calculated value that is used to reconstruct data after a failure. If a portion of a physical disk fails, Windows recreates the data that was on the failed portion from the remaining data and parity. You can create RAID-5 volumes only on dynamic disks on computers running the Windows 2000 Server or Windows Server 2003 families of operating systems. You cannot mirror or extend RAID-5 volumes. In Windows NT 4.0, a RAID-5 volume was known as a striped set with parity." -
4 striped volume
A dynamic volume that stores data that is allocated alternately and evenly (in stripes) across two or more physical disks. -
5 replica
"A complete copy of protected data residing on a single volume on the DPM server. A replica is created for each protected data source after it is added to its protection group. With co-location, multiple data sources can have their replicas residing on the same replica volume." -
6 boot sector
"A critical disk structure for starting your computer, located at sector 1 of each volume or floppy disk. It contains executable code and data that is required by the code, including information used by the file system to access the volume. The boot sector is created when your format the volume." -
7 validation
The process of comparing files on local volumes with their associated data in secondary storage by Remote Storage. Volumes that are validated ensure that the correct data is recalled from remote storage when a user attempts to open the file from a local volume. -
8 simple
Pertaining to the resiliency type for a volume that stripes data across physical disks with no resiliency in a Microsoft Storage Spaces storage pool. -
9 mirror
A volume that duplicates data across two or three physical disks in a Microsoft Storage Spaces storage pool. -
10 parity
Pertaining to the resiliency type for a volume that stripes data and parity information across physical disks in a Microsoft Storage Spaces storage pool.
