Embedded SATA RAID: Two SATA Controllers
The embedded SATA RAID controller hub is split into two controllers, SATA and sSATA (secondary SATA).
These two controllers are seen as separate RAID controllers in the Cisco IMC interface and are configurable
separately.

Note the following considerations:
■
The default setting for this embedded controller hub is SATA RAID 0, 1, and 10 support for up to
eight SATA drives (in two groups of four drives).
■
You can upgrade this to support to SATA RAID 0, 1, 10, and 5 support for up to eight SATA drives (in
two groups of four drives) by installing a RAID 5 key module on the motherboard.
■
When you order the server with this embedded controller, the controller is enabled in the BIOS.
■
You cannot downgrade from using a HW RAID controller card to using the SW RAID embedded
controller.
