The Cisco Unified Computing System™ (Cisco UCS®) E M3 Series Server is available in one form factor: a singlewide module. This singlewide version includes an Intel Xeon processor and occupies a single service-module slot in the Cisco 4000 Series ISR.

All Cisco UCS E-Series Servers are high-density, single-socket blade servers. They balance simplicity, performance, and application density while operating in an energy-efficient environment. The servers deliver next-generation Intel Xeon processor technology in combination with integrated remote lights-out management. They support multiple cores and threads in a reduced-power envelope, providing improved performance and better energy efficiency than preceding models.
