Supported RAID Controllers and Required Cables
This server supports the RAID controller options, cables, and RAID backup units shown in
Do not use the embedded MegaRAID controller and a hardware RAID controller card at the same time.
Caution
This is not supported and could result in data loss.
This server supports up to two internal PCIe-style RAID controllers, plus one external PCIe-style RAID

controller. Do not mix internal controller types in the server. You can mix internal controllers with an
external controller.
Note The embedded RAID option is available only with the SFF 16-drive backplane. It does not operate
through an expander.
The cables in this section apply to both single- and dual-CPU configurations.

1. The embedded RAID controller must be enabled in the BIOS.
2. Embedded RAID SAS drive control requires an optional SCU ROM upgrade chip to be installed on the motherboard.
3. Support for eight SAS drives requires an optional SCU upgrade ROM module on the motherboard.
4. Integrated RAID 5 support requires an optional software key.
5. The 9220-8i controller can create a RAID array with maximum 16 drives, even if it detects more than 16 drives.
6. In the 16HDD version, two controller cards can be installed to control a total of 16 drives.
7. The 9240-8i controller can create a RAID array with maximum 16 drives, even if it detects more than 16 drives.
