The UCS C240 M4 SFF server is 2-socket, 2U rack 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 UCS C240 M4 SFF server extends the capabilities of Cisco's Unified Computing System portfolio in a 2U form factor. In addition, the UCS C240 M4 SFF server provides 24 DIMM slots, up to 6 PCI Express (PCIe) 3.0 slots, up to 24 front-loading drives plus two (optional) internal SATA boot drives for a total of 26 internal drives. The C240 M4 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 LOM ports. These features combine to provide outstanding levels of internal memory and storage expandability along with exceptional performance. The Cisco UCS C240 M4 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.
