The Cisco UCS C220 M6 Rack Server delivers record-breaking performance for space-constrained environments.

Product overview

Cisco UCS® C220 M6 Rack

The Cisco UCS C220 M6 Rack Server is a 2-socket, 1-Rack-Unit (1RU) rack server offering industry-leading performance and expandability. It delivers industry-leading performance and efficiency for a wide range of workloads, including virtualization, collaboration, and bare-metal applications. Cisco UCS C-Series M6 Rack Servers can be deployed as standalone servers, as part of a Cisco Unified Computing System (Cisco UCS) managed environment, and now with Cisco Intersight 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.

In response to ever-increasing computing and data-intensive real-time workloads, the enterprise-class Cisco UCS C220 M6 server extends the capabilities of the Cisco UCS portfolio in a 1RU form factor. It incorporates 3rd Generation Intel Xeon Scalable processors, supporting up to 40 cores per socket and 33 percent more memory versus the previous generation.

The C220 M6 rack server brings many new innovations to the UCS rack server portfolio. With the introduction of PCIe Gen4 for high speed I/O, DDR4 memory bus, and expanded storage capabilities, the server delivers significant performance and efficiency gains that will improve your application performance.

      Supports the third-generation Intel Xeon Scalable CPU, with up to 40 cores per socket

      Up to 32 DDR4 DIMMs for improved performance including higher density DDR4 DIMMs (16 DIMMs per socket)

      16x DDR4 DIMMs + 16x Intel Optane persistent memory modules for up to 10 TB of memory

      Up to 3 PCIe 4.0 slots plus a modular LAN on Motherboard (mLOM) slot

      Support for Cisco UCS VIC 1400 Series adapters as well as third-party options

      Up to 10 SAS/SATA or NVMe disk drives

    Support for 12-Gbps SAS modular RAID controller in a dedicated slot, leaving the remaining PCIe Generation 4.0 slots available for other expansion cards

    Option for 10 direct-attach NVMe drives at PCIe Gen4 x4 each

      M.2 boot options

    Up to 960 GB with optional hardware RAID

      Up to three GPUs supported

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

      Dual embedded Intel x550 10GBASE-T LAN-On-Motherboard (LOM) ports

      Modular M.2 SATA SSDs for boot

Powering Next-Generation Applications

The Cisco UCS C220 M6 Rack Server is well-suited for a wide range of workloads, including:

      IT and web infrastructure

      High-performance virtual desktops

      Medium-sized and distributed databases



      Public cloud

C220 M6 servers can be deployed as standalone servers, part of a Cisco UCS managed environment, or via Cisco Intersight. When used in combination with Cisco Intersight, the C220 M6 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 UCS Manager with service profiles, templates, and policy-based management to enable rapid deployment and help ensure deployment consistency. If 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 1.11.1 (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 (
