Hello, I have bought a server platform sr1600URHSR
Has bought in addition in it backplane Intel ASR1500SASBP, has included raid in bios, but the configuration utility raid does not see disks which are connected to backplane, sees only cdrom
Are you using drives that are on the tested and compatibility list?
Have you tried to connect the drives directly to the sata port and see if they are recognised in the bios?
Have you tried to update the backplane firmware to the latest firmware? Also update the board firmware to the latest version when doing so.
All the best,
