Nvidia Mellanox EDR InfiniBand Director Switch Chassis - 216 Ports, 43Tb/s - includes 8 fans and 4 power supplies (N+N) - 12U tall switch, but requires an extra 1U to install the shelf

The Mellanox CS7520 switch system provides 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 CS7520 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, CS7520 systems provide up to 100Gb/s full bidirectional bandwidth per port. With up to 216 ports in a 12U rack space.
