Write-Back ?

The Write-Back cache setting is configurable on a per array basis. Setting to the default value means the array setting is coordinated with the controller’s general setting. The controller’s general setting option can be found in “View and Edit Config Parms” -> “Caching Parameters” -> “Write-Back Cache”. Note that cached writes are lost if power failure should occur unless cached data has been duplicated to a partner controller and a battery is supporting cache memory.
