2. Select YES in the confirmation window to proceed. Select NO to return to the Main
Menu.
After selecting YES, the RAID controller examines the total capacity of each drive
connected to the controller. If all the drives are the same, this message displays:
Do you want to have Write Caching enabled?
3. Selecting YES sets the write policy to Write-back. Selecting NO sets the write policy to
Write-through. Write-through caching is required when re-installing the operating
system (the installation will fail if set to Write-back). After an installation, you can reset
it to Write-back.
CAUTION Write-through caching reduces the risk of data loss in the event of a power failure. Write-
back caching improves performance, but the drawback is potential data loss during a power
failure. Without a UPS, a power failure can corrupt a disk drive resulting in lost data.
After the system saves the configuration, a display similar to the following appears. The
display describes the configuration created.
