"extreme server" and "super ultra" ... NO idea what you are talking about there. The SERVER supports RAID 6, but the CONTROLLER you have (H310) does NOT. For RAID 6, you will need the H710 RAID controller.
I bought this extreme server ( it is super ultra)) to use for Backing up stuff from Personal home computer. So its with great sadness i figure , RAID 6 doesnt even work? I have 4x450GB SAS for O.S, 4x2TB SATA for storage. However, in the PERC's BIOS setup , there is only RAID 0, RAID 1, RAID 5 and RAID 10 to choose from ? Ist RAID 6 unsupported by this server ?    ///Ahrle
DELL. R-520. No RAID 6-Support? :/
