  • Internal, auxiliary storage. The server supports these options:

    • When SAS/SATA drives are populated in the auxiliary rear drive bays, they can be controlled by a storage controller card in PCIe slot 11 or 10.

    • When NVMe SSDs are populated in the auxiliary drive bays, you must have an NVMe switch card in PCIe slot 10.

    • Cisco Boot-Optimized M.2 RAID Controller (module with two slots for SATA M.2 drives, plus an integrated SATA RAID controller that can control the two SATA M.2 drives in a RAID 1 array)

For a detailed list of storage controller options, see Supported Storage Controllers and Cables.
