The Cisco UCS C245 M8 Rack Server is perfectly suited for a wide range of storage and I/O-intensive applications such as big data analytics, databases, collaboration, virtualization, consolidation, AI/ML and high-performance computing supporting up to two AMD CPUs in a 2RU form factor.

The Cisco UCS C245 M8 Rack Server extends the capabilities of the Cisco UCS rack server portfolio. It powers 4th Gen AMD EPYC Processors with 100 percent more cores per socket designed using AMD’s chiplet architecture. With advanced features like AMD Infinity Guard, compute-intensive applications will see significant performance improvements and will reap other benefits such as power and cost efficiencies.

You can deploy the Cisco UCS C-Series rack servers as part of the Cisco Unified Computing System managed by Cisco Intersight® or Cisco UCS Manager to take advantage of Cisco® standards-based unified computing innovations that can help reduce your Total Cost of Ownership (TCO) and increase your business agility or as standalone servers.

The Cisco UCS C245 M8 Rack Server brings many innovations to the UCS AMD rack server line. With the introduction of PCIe Gen 5.0 expansion slots for high-speed I/O, a DDR5 memory bus, and expanded storage capabilities, the server delivers significant performance and efficiency gains that will greatly enhance application performance. Features include:

     Support for up to two 4th Gen AMD EPYC CPUs in a server designed to drive as much as 256 CPU cores (128 cores per socket)

     Up to 24 DDR5 DIMM slots, yielding up to 6 TB of capacity, using 256 GB DIMMs (12 DIMMs per socket)

     Up to 4800 MT/s DDR5 memory

     Up to 8 x PCIe Gen 4.0 slots or up to 4 x PCIe Gen 5.0 slots, plus a hybrid modular LAN on motherboard (mLOM) /OCP 3.0 slot (details below)

     Support for Cisco UCS VIC 15000 Series adapters as well as a host of third-party NIC options

     Up to 28 hot-swappable small-form-factor (SFF) SAS/SATA or NVMe drives (with up to 8 direct-attach NVMe drives)

    New tri-mode RAID controller supports SAS4 plus NVMe hardware RAID

     M.2 boot options

    Up to two 960GB SATA M.2 drives with hardware RAID support

    Up to two 960GB NVMe M.2 drives with NVMe hardware RAID

     Support for up to Eight GPUs

     Modular LOM / OCP 3.0

    One dedicated PCIe Gen4x16 slot that can be used to add an mLOM or OCP 3.0 card for additional rear-panel connectivity

    mLOM slot that can be used to install a Cisco UCS Virtual Interface Card (VIC) without consuming a PCIe slot, supporting quad-port 10/25/50 Gbps or dual-port 40/100/200 Gbps network connectivity

    OCP 3.0 slot that features full out-of-band management for select adapters

High performance for data-intensive applications

The Cisco UCS C245 M8 Rack Server is well suited for a wide range of enterprise workloads, including:

     Virtualization and consolidation

     Big data and analytics



     Small and medium-sized business databases

     Storage servers

     Enterprise high-performance appliances

Cisco UCS C245 M8 Rack Servers can be deployed as part of a Cisco UCS–managed environment, through Cisco Intersight, or standalone. When used in combination with Cisco Intersight, the C245 M8 brings the power and automation of unified computing to enterprise applications, including Cisco SingleConnect technology, drastically reducing switching and cabling requirements.

Cisco Intersight leverages the familiar capabilities of Cisco UCS Manager with service profiles, templates, and policy-based management to enable rapid deployment and help ensure deployment consistency. It also enables end-to-end server visibility, management, and control in both virtualized and bare-metal environments.

The Cisco Integrated Management Controller (IMC) delivers comprehensive out-of-band server management with support for many industry standards, including:

     Redfish Version 1.13.0 (2021.1 schema0)

     Intelligent Platform Management Interface (IPMI) v2.0

     Simple Network Management Protocol (SNMP) v2 and v3


     Simple Mail Transfer Protocol (SMTP)

     Key Management Interoperability Protocol (KMIP)

     cKVM (all-new Cisco KVM)

     Command-line interface (CLI)

     XML API

Management Software Development Kits (SDKs) and DevOps integrations exist for Python, Microsoft PowerShell, Ansible, Puppet, Chef, and more. For more information about integrations, see Cisco DevNet (
