Do you mean sir in system cache on ESRT 2 that doesn't have BBU capabilty, the write back will turn off in system Raid. if onboard RAID will use? may i know and ask if our Intel server board s1200bts has a onboard RAID which in system cache writing will turn on the write back cause as you said before ERST II doesn't have BBU capability,
So therefore i will turn off the write cache back off.
Thanks very much sir john_s@intel for your support, appreciated much for you technical support.
Thank you again:)
