UCS C420 M3 without CPUs, memory DIMMs, disk drives, PCIe cards, or power supplies
The Cisco UCS® C420 M3 Rack Server is a high-density, 4-socket, 2-rack-unit (2RU) rack server designed for computing, I/O, storage, and memory-intensive standalone applications. The Cisco UCS C420 M3 extends the capabilities of the Cisco Unified Computing System™ (Cisco UCS) using Intel Xeon processor E5-4600 Series multicore processors to deliver increased performance and efficiency.
The Cisco UCS C420 M3 is part of the Cisco UCS solution, which combines rack and blade servers with networking and storage access into a single unified system. Centrally configured through unified, model-based management, Cisco UCS simplifies and accelerates deployment of enterprise-class applications running in bare-metal, virtualized, and cloud-computing environments.
Designed for enterprise-class performance and scalability, the Cisco UCS C420 M3 combines the advantages of 4‑socket computing with the cost-effective Intel Xeon processor E5-4600 product family for demanding virtualization, database, and high-end high-performance computing (HPC) workloads. The dense and expandable Cisco UCS C420 M3 is a balanced, high-performance platform that complements the Cisco UCS Rack Server portfolio. The 2RU Cisco UCS C420 M3 supports 48 DIMM slots, 16 disk drives, seven PCIe expansion slots, and four 1 Gigabit Ethernet LAN-on-motherboard (LOM) ports. It uses unique Cisco UCS and virtual interface card (VIC) technology and delivers one-wire participation in Cisco UCS domains. The Cisco UCS C420 M3 interfaces with Cisco UCS using another Cisco innovation: the Cisco UCS VIC 1225. The Cisco UCS VIC 1225 is a dual-port Enhanced Small Form-Factor Pluggable (SFP+) 10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE)-capable PCI Express (PCIe) card designed exclusively for Cisco UCS C-Series Rack Servers. It incorporates Cisco’s next-generation converged network adapter (CNA), providing investment protection for feature releases. The card enables a policy-based, stateless, agile server infrastructure that can present up to 256 PCIe standards-compliant interfaces to the host that can be dynamically configured as either network interface cards (NICs) or host bus adapters (HBAs). In addition, the Cisco UCS VIC 1225 supports Cisco® Data Center Virtual Machine Fabric Extender (VM-FEX) technology, which extends the Cisco UCS fabric interconnect ports to virtual machines, simplifying server virtualization deployment.
