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 10-drives server SE-CL-L3 :
• The pSATA controller controls up to eight front SATA drives (drive bays 1–8).
• 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.
Enabling SATA Mode For the Embedded Controllers
This procedure uses the server's BIOS Setup Utility.
If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set
to
LSI SW RAID
mode.
Note
Step 1
Boot the server and press F2 when prompted to enter the BIOS Setup utility.
Step 2
Set the SATA mode:
a) Choose the Advanced tab, and then choose LOM and PCIe Slots Configuration.
b) 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.
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.
Note
• Disabled—Disable the embedded pSATA RAID controller.
c) For the secondary sSATA controller, select M.2 and then choose one of the options from the dialog:
• LSI SW RAID—Enable the embedded sSATA RAID controller for control of internal SATA M.2 drives.
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.
Note
This menu option does not appear when the server has no M.2 mini storage module, or when no SATA
M.2 drive is installed in the mini-storage module.
Note
• AHCI—Enable control of the internal SATA M.2 drives by AHCI through your OS rather than the embedded
RAID controller.
• Disabled—Disable the embedded sSATA RAID controller.
