I have put a new RAID card (UCS-51) into my Dell Precision T5400.
I have connected this to 2 x 1TB SATA disks.
I have configured a mirror array in the RAID bios.
The array shows when I boot computer up.
Sadly every OS I try and install (Win7 & ESXi) says there is no storage devices found.
Can anyone assist? Pics below...
