Supported RAID Controllers and Required Cables
This server supports the RAID controller options and cable requirements shown in Table C-1 for small
form factor drives and Table C-2 for large form factor drives.
Caution Do not mix controller types in the server. Do not use the embedded MegaRAID controller and a hardware
RAID controller card at the same time. This is not supported and could result in data loss.
