Distributed Data Guarding—(RAID 5) stores parity data across all the physical drives in
the array and allows more simultaneous read operations and higher performance than
data guarding (RAID 4). If a drive fails, the controller uses the parity data and the data
on the remaining drives to reconstruct data from the failed drive. The system then continues
operating with a slightly reduced performance until you replace the failed drive.
Enhanced Mirroring—(RAID 1E) is used when there are more than two physical disks.
Each mirrored stripe is written to a disk and is mirrored to an adjacent disk. If a failure
is detected, the data is rebuilt using the data from the mirrored stripes on the other drives.
Unknown—The Storage Agents cannot determine the fault tolerance of this logical drive.
You might need to upgrade your driver software or Storage Agents.
Stripe Size—The size of a logical drive stripe or group of data written to a physical drive in
kilobytes. It might be zero in some fault-tolerance modes like None and Mirroring.
Percent Rebuild Complete—Displays the percent complete of the resynchronization of the data.
When the value reaches 100, the rebuilding process is complete. The logical drive continues
to operate with slightly reduced performance during the rebuild. This value is only active when
the logical drive has a status of Rebuilding.
OS Assigned Name—Displays the operating system name associated with this logical drive.
