Overview

The UCSC X24g tri-mode M1 front mezzanine module intended for use in Cisco UCS X-Series compute nodes, starting with Cisco UCS X210c M8.

Each Cisco UCS X24g tri-mode M1 front mezzanine module consists of the following components:

  • UCS X24g tri-mode RAID controller

  • Up to six (6) SAS/SATA/NVMe SSD drives. Each drive slot supports either SAS, SATA or NVMe U.3 SSDs (RAID Controller)

    • SAS: 12G, 24G in a x1 config

    • SATA: 6G in a x1 config

    • NVMe: Gen 4 in a x2 config

  • Supercap

    • FBU345 or smaller size (TBD)
