Supported Storage Controllers and Cables

This server supports a single, PCIe-style, SAS RAID or HBA controller that plugs into a dedicated internal
socket.
Note 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.
NVMe PCIe SSDs cannot be controlled by a SAS/SATA RAID controller.
Note
This server supports the RAID and HBA controller options and cable requirements shown in the following
table.
