Nvidia Mellanox EDR InfiniBand Director Switch Chassis - 648 Ports, 130Tb/s - includes 20 fans and 10 power supplies (N+N) - 28U tall switch, but requires an extra 1U to install the shelf

The Mellanox CS7500 switch system provides the high performing fabric solution by delivering high bandwidth and low latency to enterprise data centers (EDC), high-performance computing (HPC) and embedded environments. Networks built with the CS7500 system can carry converged traffic with the combination of assured bandwidth and granular quality of service. Built with Mellanox's 6th and 7th generation of Switch-IB and Switch-IB 2 switch devices, CS7500 systems provide up to 100Gb/s full bidirectional bandwidth per port. With up to 648 ports in a 28U rack space.
