Embedded SATA RAID Controller
Embedded SATA RAID: Two SATA Controllers
The embedded RAID Patsburgh controller hub (PCH) 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.

The first SATA controller controls front-facing drives 1–4; it can also control the two internal SATA
SSD boot drives (see

The secondary sSATA controller controls front-facing drives 5–8 (see
SATA and sSATA Listing of Drives in LSI SW RAID Utilities
When configuring RAID groups, you cannot create a group that spans more than four drives.
The first SATA controller can control a RAID group of up to four drives, comprised of only front

Each controller is listed separately in the BIOS. You can select the boot order of the controllers in
the BIOS (use the Boot Options tab in the BIOS Setup Utility).
To set the boot order for virtual drives, use the LSI Embedded RAID Configuration Utility
