Disk Cache Policy

Does my controller support this feature? See Supported Features.

Set the physical disk caching policy of all members of a virtual disk by enabling the Disk Cache Policy. When this feature is enabled, the physical disk writes data to the physical disk cache before writing it to the physical disk. Because it is faster to write data to the cache than to a disk, enabling this feature improves system performance.

The cache policies are:

  • EnabledDisk Cache Policy is enabled.
  • DisabledDisk Cache Policy is disabled.
  • Unchanged — The disk uses the default write cache mode.
