Cisco Barebone System – 1U Rack-mountable – 2 x Processor Support – Intel C620 Chip – 3 TB DDR4 SDRAM DDR4-2666/PC4-21300 Maximum RAM Support – 24 Total Memory Slots – 12Gb/s SAS RAID Supported Controller – Matrox G200e 8 MB Graphic(s) – 10 2.5″ Bay(s) – Processor Support (Xeon Platinum, Xeon Gold, Xeon Silver, Xeon Bronze) – 10 Gigabit Ethernet, Gigabit Ethernet – Intel Optane Memory Ready – 2 USB 3.0 Port(s)

The UCS C220 M5 SFF server extends the capabilities of Cisco's Unified Computing System portfolio in a 1U form factor with the addition of the Intel® Xeon® Processor Scalable Family, 24 DIMM slots for 2666MHz DIMMs and capacity points up to 128GB, two 2 PCI Express (PCIe) 3.0 slots, and up to 10 SAS/SATA hard disk drives (HDDs) or solid state drives (SSDs). The C220 M5 SFF server also includes one dedicated internal slot for a 12G SAS storage controller card.

The latest update includes support for 2933 MHz DDR4 memory that is used with the latest 2nd Generation Intel® Xeon® Scalable Processors. With this combination and the new 512GB Intel® OptaneTM DC Persistent Memory (DCPMM – Data Center Persistent Memory Module), up to 9TB of memory is possible (12x256GB DDR4 DIMMs1 and 12x512GB DCPMMs)

The C220 M5 server included one dedicated internal modular LAN on motherboard (mLOM) slot for installation of a Cisco Virtual Interface Card (VIC) or third-party network interface card (NIC), without consuming a PCI slot, in addition to 2 x 10Gbase-T Intel x550 embedded (on the motherboard) LOM ports.

The Cisco UCS C220 M5 server can be used standalone, or as part of the Cisco Unified Computing System, which unifies computing, networking, management, virtualization, and storage access into a single integrated architecture enabling end-to-end server visibility, management, and control in both bare metal and virtualized environments.
