The Cisco UCS C220 M4 LFF rack server is a server from Cisco, designed for both performance and expandability over a wide range of storage-intensive infrastructure workloads from big data to collaboration. The enterprise-class UFCS C220 M4 LFF server extends the capabilities of Cisco's Unified Computing System portfolio in a 1U form factor. In addition, the UCS C220 M4 SFF server provides 24 DIMM slots, up to 4 drives and 2 x 1 GbE LAN-on-motherboard (LOM) ports delivering outstanding levels of density and performance in a compact 1U package. The C220 M4 SFF server includes a 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 1 GbE embedded (on the motherboard) LOM ports. These features combine to provide outstanding levels of internal memory and storage expandability along with exceptional performance. The Cisco UCS C240 M4 LFF 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.
