Storage Controller Card Firmware Compatibility

Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco
IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the storage
controller firmware using the Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible
level.
See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring
server components to compatible levels:

RAID Backup (Supercap)

This server supports installation of one supercap unit. The unit mounts to a bracket in-line with the fan modules.
The optional SCPM provides approximately three years of backup for the disk write-back cache DRAM in
the case of a sudden power loss by offloading the cache to the NAND flash.
