disk media, so you risk losing the data in the disk cache if a power
failure occurs. The data is unrecoverable.
— IO Policy: The IO policy applies to read operations on a specific virtual drive. It does not affect the read-ahead
cache.
Direct: Read operations are not buffered in cache memory. Data is transferred to the cache and the host
concurrently. If the same data block is read again, it comes from cache memory. This setting is the default.
Cached: Read operations are buffered in cache memory before they are sent to the host.
— Drive Policy: Specify the drive cache policy.
Enable: Enable the drive cache.
Disable: Disable the drive cache.
NoChange: Leave the current drive cache policy as is. This setting is the default.
— Disable BGI: Specify the background initialization status.
No: Leave background initialization enabled. A new configuration can be initialized in the background while
you use WebBIOS to perform other configuration tasks. This setting is the default.
Yes: Select Yes if you do not want to allow background initialization for configurations on this controller.
— Select Size: Specify the size of the virtual drive or drives in MB, GB, or TB. Usually, this size is the full size for the
RAID 1 array shown in the Configuration panel on the right. You can specify a smaller size if you want to create
other virtual drives on the same drive group.
— Update Size: Click Update Size to update the Select Size Field value for the selected RAID levels.

virtual drive.
