Dell Shared PowerEdge RAID Controller 8 Cards For Dell PowerEdge VRTX Systems User’s Guide

Physical disk write cache policy

Management utilities provide the option to modify disk cache policies for physical disks associated with a virtual disk. The following options are available for the Shared PERC controller:

Option
Description
Enabled
Enables physical disk cache for drives associated with the selected virtual disk.
Disabled
Disables physical disk cache for drives associated with the selected virtual disk.
Default
The default cache policy on the physical disk is used. See the physical disk documentation for details on the default setting.
  • WARNING: Enabling physical disk cache is not recommended for disks with critical data as a power failure may result in the loss of data prior to it being flushed to the persistent media.
  • NOTE: Any change to the physical disk cache applies to all virtual disks in an entire disk group. It is not possible to have different cache policies on virtual disks from the same disk group.
