Storage Redundancy Check Options; Figure 81. Settings - Storage Caching Options Configuration - Intel MFSYS25V2 Service Manual

Drive write-back cache is disabled by default because there are some risks involved. In the
case of a sudden power loss to the chassis, all hard drives would immediately power off. If
there were data in a cache waiting to be written to the drive, it would be lost and
unrecoverable. To avoid this situation, provide a power backup (such as an UPS) for the
chassis. The backup power supply should be capable of and configured to trigger an
orderly shutdown of each server in the chassis.

Storage Redundancy Check Options

The purpose of redundancy check is to identify inconsistencies. While the redundancy
check does make the data consistent, it does not necessarily correct errors. Redundancy
check does provide the user with an indication that drive information may be suspect.
The customer can Enable or Disable Redundancy Check schedule by themselves.
