Compute and I/O optimized for industry-leading performance

The Cisco UCS C480 ML M5 is a purpose-built enterprise-class rack server for deep learning that is compute- and I/O-optimized to deliver industry-leading performance for faster model training irrespective of training data size.

The Cisco UCS C480 ML M5 can be managed with Cisco Intersight. Cisco Intersight is a new cloud-based management platform that uses analytics to deliver proactive automation and support. By combining intelligence with automated actions, you can reduce costs dramatically and resolve issues more quickly.

The C480 ML M5 servers can be deployed as standalone servers or in a Cisco UCS–managed environment. When used in combination with Cisco UCS Manager, the C480 ML M5 brings the power and automation of unified computing to enterprise applications, including Cisco SingleConnect technology, drastically reducing switching and cabling requirements. Cisco UCS Manager uses 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 1.01 (v1.01)

     Intelligent Platform Management Interface (IPMI) v2.0

     Simple Network Management Protocol (SNMP) v2 and v3


     Simple Mail Transfer Protocol (SMTP)

     HTML5 GUI

     HTML5 virtual Keyboard-Video-Mouse (vKVM)

     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.

[1] Each Intel Optane DC Persistent Memory Module requires a DDR4 DIMM for deployment. For example, if you are planning to use 12 Intel Optane DC Persistent Memory Modules, you will need 12 DDR4 DIMMs. In this scenario, the size of each of the DCPMMs must be the same. Similarly, the size of each of the DDR4 DIMMs must the same. But the size of the DCPMMs don’t need to be the same as the size of the DDR4 DIMMs.
