program the controller's suboem-id to the correct value for the server SKU. If you do not do this, drive enumeration might
not display correctly in the software. This issue does not affect servers controlled in UCSM mode.

Replacing a Boot-Optimized M.2 RAID Controller Module
The Cisco Boot-Optimized M.2 RAID Controller module connects to the mini-storage module socket on the
motherboard. It includes slots for two SATA M.2 drives, plus an integrated 6-Gbps SATA RAID controller
that can control the SATA M.2 drives in a RAID 1 array.
Cisco Boot-Optimized M.2 RAID Controller Considerations
Review the following considerations:
• The minimum version of Cisco IMC that support this controller is 4.0(4) and later.
• This controller supports RAID 1 (single volume) and JBOD mode.
• A SATA M.2 drive in slot 1 (the top) is the first SATA device; a SATA M.2 drive in slot 2 (the underside)
is the second SATA device.
• The name of the controller in the software is MSTOR-RAID.
• A drive in Slot 1 is mapped as drive 253; a drive in slot 2 is mapped as drive 254.
