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.
