Appendix C RAID Controller Considerations
Supported RAID Controllers and Required Cables
Supported RAID Controllers and Required Cables
This server supports the RAID controller options, cable requirements, and RAID backup units shown in
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.
Note
This server supports up to two PCIe-style RAID controllers. Do not mix controller types in the server.
Note
The SAS expander is required for the SFF 24-drive option and the LFF 12-drive option.
The SFF 16-drive option does not use the SAS expander.
Note
The embedded RAID option is available only with the SFF 16-drive backplane. It does not operate through
an expander.
