The Cisco UCS C250 server, which is a part of the Cisco UCS C-Series Rack-Mount Server family, operates in a wide range of data center environments, including those environments that use the Cisco Unified Computing System, Cisco Nexus family products, and discrete Ethernet and Fibre Channel switches from Cisco and third parties.

Supporting up to 384 GB of DDR3 main memory, this server is a high-performance, memory-intensive, two-socket, two rack unit (2 RU) server that increases performance and capacity for demanding virtualization and large dataset workloads.

Table 1-1 Hardware Features of the Server  

Feature or Component	Cisco UCS C250 Server
Enclosure	Two rack unit (2RU) chassis.
Processors	Two quad-core Intel Xeon processors (Xeon 5500 Series for UCS C250 Generation M1 and Xeon 5600 Series for UCS C250 Generation M2).
Memory	48 DIMM1 slots supporting up to 384 GB of industry-standard DDR32 main memory.
Storage	Up to eight internal SAS3 or SATA4 hard drives, supporting up to 4 TB total. Server Generation M2 only—There is also one internal USB port on the motherboard that you can use with a USB thumb drive (see Figure 3-4).
Disk Management	Factory-configured RAID5 support options: •RAID 0 and 1 support for up to eight SAS or SATA drives with the optional LSI SAS 3081E-R Controller card. •RAID 0, 1, 5, 6, 10, 50, and 60 support for up to eight SAS or SATA drives by using the LSI MegaRAID SAS 9261-8i RAID Controller cards.
PCIe I/O	Up to five PCIe6 expansion cards, plugged into horizontal riser card sockets: •Two half-length, standard-profile rear-panel slots (with riser card). •Three half-length, low-profile rear-panel slots (with riser card).
Network and management I/O	The server provides these rear-panel connectors: •Four 10/100/1000 Gigabit Ethernet ports (RJ-45 connectors). These integrated Gigabit ports support the Wake on LAN (WoL) and TCP/IP Offload Engine (TOE) standards. •Two 10/100 Ethernet management ports (RJ-45 connector). •One DB9 serial connector. •One 15-pin VGA7 connector. •Two USB8 2.0 connectors. The server also has one front-panel console connector (with supplied KVM9 cable provides DB15 video, DB9 serial, and two USB 2.0 connectors).
Removable media devices	One internal DVD drive. The drive supports the following media types: CD-R, CD-ROM, CD-RW, DVD+R, DVD+RW, DVD-R, DVD-ROM, DVD-RW, +R DL
Power	Up to two power supplies, each with a maximum output of 750W.
Cooling	Five fan modules that force front-to-rear cooling with four fans in each module; also one fan in each power supply.

1 DIMM = dual inline memory module 2 DDR = double data rate (transfer mode) 3 SAS = serial attached SCSI 4 SATA = serial advanced technology attachment 5 RAID = redundant array of independent disks 6 PCIe = peripheral component interconnect express 7 VGA = video graphics array 8 USB = universal serial bus 9 KVM = keyboard, video, mouse
