Preserving the Controller Cache
Note: This option is available in the uEFI interface only.
Follow the on-screen instructions to toggle the controller's cache preservation policy; clear the preserved
cache for one or more logical drives; and check the controller cache preservation state.
Enabling and Disabling Controller Cache Preservation
This option toggles the controller cache preservation state. With cache preservation enabled, the system
preserves the controller's DDR cache to prevent data loss in the event of (1) a power failure or unsafe
shutdown of external enclosures while the host system, with the controller, still has power; and (2)
connectivity problems with drives.
"Dirty pages" (data that have not been committed to disk) are restored to the cache when power is
restored and the logical drives on the controller are back online. Once the preserved cache is restored,
the controller ushes the data to disk using its normal scheduling mechanism.
Note: You cannot enable maxCache read and/or write caching on a controller with
cache preservation enabled. In addition, the following operations are not permitted
on a controller in the cache preserved state:
• Creating a logical drive
• Changing the Performance mode
• Running a consistency check
• Changing the RAID Level of a logical drive
• Forcing a logical drive online or ofine
• Changing the cache page size
To enable controller cache preservation:
