• When you order the server with this embedded controller, the controller is enabled in the BIOS. Instructions
for enabling the controller are included for the case in which a server is reset to defaults. See
Enabling
SATA Mode , on page 137
.
• The required drivers for this controller are already installed and ready to use. However, if you will use
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 138
.
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.
• The primary pSATA controller controls only the optional DVD drive; otherwise, it is disabled.
• The secondary sSATA controller controls two internal M.2 SATA drives, when they are present in the
M.2 mini-storage module option.
If the NVMe mini-storage module option is installed instead, the sSATA controller is automatically
disabled.
• Each controller is listed separately in the BIOS. You can enable or disable the controllers in the BIOS.

Enabling SATA Mode
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) For the primary pSATA controller, select
pSATA
and then choose one of the options from the dialog:
• SWR—Enable the embedded pSATA RAID controller.
• AHCI—Enable control of a DVD drive by AHCI through your OS rather than the embedded RAID controller.
• Disabled—Disable the embedded pSATA RAID controller.
d) For the secondary sSATA controller, select
M.2
and then choose one of the options from the dialog:
• SWR—Enable the embedded sSATA RAID controller for control of internal SATA M.2 drives.
• 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.
Step 2
Press
F10
to save your changes and exit the utility.
