part of a pool for all virtual disks controlled by the controller.

Rebuild
Select Rebuild to rebuild one or more failed physical disks. For information on performing a physical disk
rebuild, see Performing A Manual Rebuild Of An Individual Physical Disk .
Several of the controller configuration settings and the virtual disk settings affect the actual rate of
rebuild. The factors include the rebuild rate setting, virtual disk stripe size, virtual disk read policy, virtual
disk write policy, and the amount of workload placed on the storage subsystem. For information on
getting the best rebuild performance from your RAID controller, see the documentation at
dell.com/
support/manuals .
The listed rates in the following table were taken during single disk failure with no I/O. Rates vary
depending on type, speed and number of hard drives present in array; as well as which controller model
and enclosure configuration are being used.
