Hello,   Yes, the T310 does support using the H700i and it does require different cabling. W846K looks to be the correct part. I would recommend cabling SAS A and SAS B both.   [IMAGE]
We have a PowerEdge T310 whose function we want to change to large, long term storage.  Using the service tag, a Dell sales rep graciously sold us multiple 4 TB Dell drives without telling us the Perc6 controller would not support them. No problem. We figured we would go with the H700I. However the backplane on the hotswap bay does NOT use the same cabling as what appears to be on the inputs of the H700I Raid Controller.  It's a large ribbon cable that goes to the Perc6.  Is it even possible to run the H700I in this server or did Dell sell us drives that we can't use?   The server will support UEFI booting if we can ever get the drives to actually "work" with a controller.  Thanks in advance.
