Appendix C RAID Controller Considerations

Supported RAID Controllers and Required Cables

Supported RAID Controllers and Required Cables

This server supports the RAID controller options and cable requirements shown in Table C-1for small form factor drives and Table C-2for 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.
