Cisco UCS C220 M3, I would position it differently from the Dell Precision because this is a 1U rack server, designed primarily for server and infrastructure workloads. Cisco specifies support for up to two Intel Xeon E5-2600/E5-2600 v2 processors, 16 DIMM slots, and up to eight drives depending on configuration. (Cisco)
