Write-Cache Policy for Cisco 12G SAS Modular RAID Controllerįor this server and other Cisco Generation M5 servers, the default write-cache policy for the Cisco Modular RAID controller Power loss by offloading the cache to the NAND flash.įor supercap unit replacement instructions, see Replacing the Supercap (RAID Backup). The optional SCPM provides approximately three years of backup for the disk write-back cache DRAM in the case of a sudden The unit mounts to a bracket in-line with the fan modules. This server supports installation of one supercap unit. This issue does not affect servers controlled in UCSM mode. If you do not do this, drive enumeration might not display correctly in the software. This is necessary to program the controller's suboem-id
