Figure 75. Settings - Storage Caching Options Configuration - Intel MFSYS25 - AXXPSU 1000W Power Supply Module User Manual

This is a chassis-wide setting, that is, all drive write-back caches are either enabled or all
are disabled.
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.
