The Cisco UCS C240 M6 Rack Server is a 2-socket, 2-Rack-Unit (2RU) rack server offering industry-leading performance and expandability. It supports a wide range of storage and I/O-intensive infrastructure workloads, from big data and analytics to collaboration. Cisco UCS C-Series M6 Rack Servers can be deployed as standalone servers or as part of a Cisco Unified Computing System (Cisco UCS) managed environment, and now with Cisco Intersight is able to take advantage of Cisco’s standards-based unified computing innovations that help reduce customers’ Total Cost of Ownership (TCO) and increase their business agility.
The server accommodates up to 12 front facing SAS-only LFF drives, up to 4 mid-plane SAS-only LFF drives, and up to 4 rear-facing SFF drives (SAS or SATA or NVMe).
If a Midplane is installed GPUs are not supported.
Chassis Options
Drive Rules and Limitations
- You can mix HDDs and SSDs as long as you keep all HDDs in their own RAID volume and all SSDs in their own RAID volume.
- You can mix SAS HDDs and SAS/SATA SSDs when using the Cisco 12G SAS RAID controller or Cisco 12G SAS HBA.
- If you order any SFF NVMe rear drives, you must also order two CPUs.
- SED drives can be mixed with non-SED drives in Table 11 on page 27
- 2.5-inch SFF NVMe drives are connected directly to the CPU, and are not managed by the RAID controller or SAS HBA.
- You cannot mix SAS/SATA with NVMe rear drives. They must be all SAS/SATA or all NVMe
- A midplane kit (PID UCSC-MPSTOM6L-KIT) is required
- If a Midplane is installed GPUs are not supported.
VROC Requirments
- Intel® VROC is only supported with Intel drives
- Intel® VROC enablement key factory pre-provisioned to BIOS - no additional licensing required.
- Small Form Factor (SFF) drive support (only)
- No battery backup (BBU) or external SuperCap needed
- Software-based solution utilizing Intel SFF NVMe direct connected to Intel CPU
- RAID 0/1/5/10 support
- Windows, Linux, VMware OS support.
- Host Tools- Windows GUI/CLI, Linux CLI.
- UEFI Support- HII Utility, OBSE.
- Intel VROC NVMe operates in UEFI mode only
Memory Options
32 DDR4 DIMM slots: 16, 32, 64, 128 and 256 GB up to 3200 MHz Support for the Intel Optane DC persistent memory (128G, 256G, 512G). DIMM mixing is not allowed when PMem are installed; in these cases, all DIMMs must be the same type and size.
Supported Memory
- Clock speed: 3200 MHz
- Ranks per DIMM: 1, 2, 4, or 8
- Operational voltage: 1.2 V
- Registered ECC DDR4 DIMMS (RDIMMs), Load-reduced DIMMs (LRDIMMs), or Intel® Optane™ Persistent Memory Modules (PMem).
Max Memory:
- 4 TB: 32 x 128 GB DDR4 DIMMs
- 10 TB: 16 x 128 GB DDR4 DIMMs and 16 x 512 GB Intel® Optane™ Persistent Memory Modules (PMem).
PCIe Expansion Options
8 PCIe 4.0 slots, 1 dedicated 12-Gbps RAID controller slot and 1 dedicated mLOM slot. With 8PCIe slots the system is able to support up to 5 A10 Single Wide GPUs. Slots 4, 5, and 6 on riser card 2A accommodate single-wide GPUs.
Riser 2 and 3 connect to CPU 2 and if they are not installed then you will need to add the Riser Filler Blanks for optimal air flow.

Not all risers are available in every server configuration option
GPU 256 GB DIMMs cannot be combined with GPU cards. When a GPU is ordered, the server comes with low-profile heatsinks PID (UCSC-HSLP-M6=) and needs to select a special air duct PID (UCSC-ADGPU-240M6=) for GPUs.
Power & Fan Units
The chassis is equipped with six fans and two power supplies. In a server with two power supplies, both power supplies must be identical. Hot-pluggable, redundant 1050W AC, 1050W DC, 1600W AC, and 2300W AC
