Cisco UCS C240 M5 Service Manual

RAID Controller Migration
The SFF, 8-drives version of the server (UCSC-C240-M5S) can use the software-based, embedded SATA
RAID controller to control front-loading SATA drives.
For SFF, 8-drives version only (UCSC-C240-M5S): Do not mix controller types in the server. Do not use
the embedded SATA controller and a hardware-based RAID controller card to control front-loading drives
at the same time. This combination is not supported and could result in data loss.
