The Cisco SFS 7000D delivers an ideal combination of price, performance, and packaging for building high-performance server clusters of all sizes. The Cisco SFS 7000D provides 24 InfiniBand 4X ports that can operate in double data rate (DDR) or single data rate (SDR) mode, which delivers 20- or 10-Gbps server connectivity respectively. The Cisco SFS 7000D is a fully nonblocking, 960-Gbps cross-sectional bandwidth switch fabric that has less than 200 nanoseconds (ns) of port-to-port latency. In common with the Cisco SFS 7000P, the Cisco SFS 7000D comes with the embedded Cisco InfiniBand Subnet Manager, which is capable of running large clusters in a single, compact 1 rack unit (1RU) chassis.
