Embedded SATA RAID: Two SATA Controllers

The embedded RAID platform controller hub (PCH) is split into two controllers: primary SATA (pSATA)
and secondary SATA (sSATA). These two controllers are seen as separate RAID controllers in the Cisco
IMC interface and are configurable separately.
• SFF 8-drives server UCSC-C240-M5S (only):
• All other versions of the server:
• Each controller is listed separately in the BIOS. You can enable or disable the controllers in the BIOS.

Enabling SATA Mode For the Embedded Controllers

This procedure uses the server's BIOS Setup Utility
Step 1 Set the SATA mode:
a) Boot the server and press F2 when prompted to enter the BIOS Setup utility.
b) Choose the Advanced tab, and then choose LOM and PCIe Slots Configuration.
c) Server version UCSC-C240-M5S only: For the primary pSATA controller, select pSATA, and then choose one of
the options from the dialog:
• LSI SW RAID—Enable the embedded pSATA RAID controller.
Note
• Disabled—Disable the embedded pSATA RAID controller.
this controller with Windows or Linux, you must download and install additional drivers for those
operating systems. See Installing LSI MegaSR Drivers For Windows and Linux, on page
◦ The pSATA controller controls up to eight front-loading SATA drives.
◦ The sSATA controller controls two internal SATA M.2 drives, when they are present in the M.2
mini-storage module option.
If the M.2 mini-storage module is not present, or if M.2 NVMe drives are installed in the
mini-storage module, the sSATA controller is automatically disabled.
◦ The pSATA controller is disabled.
◦ The sSATA controller controls two internal SATA M.2 drives, when they are present in the SATA
mini-storage module option.
If the M.2 mini-storage module is not present, or if M.2 NVMe drives are installed in the
mini-storage module, the sSATA controller is automatically disabled.

This menu option does not appear when the server is set to boot in Legacy mode (UEFI mode is
required). To change the boot mode, use the BIOS setting for Boot Options > Boot Mode.
