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 the small form factor version, or Table C-2for the large form factor version of the server.

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 Dual controllers are not supported.

Note The cables in this section apply to both single- and dual-CPU configurations.

Table C-1lists the RAID options for the small form factor (SFF) version of the server.

1.SCPM = SuperCap power module (the RAID backup unit).

2.The embedded RAID controller must be enabled in the BIOS.

3.Support for eight SAS drives requires an optional SCU upgrade ROM module on the motherboard.

4.Embedded RAID 5 support requires an optional software key module.

5.The 9220-4i controller can create a RAID array with maximum 4 drives, even if it detects more than 4 drives.
