SX6512 216-port Non-blocking FDR 56Gb/s InfiniBand Switch System


The SX6512 switch system provides the highest-performing fabric solution in a 9U form factor factor by delivering 24.2Tb/s of non-blocking bandwidth with 170ns to 510ns port latency.

Built with Mellanox’s 5th-generation SwitchX® InfiniBand switch device, the SX6512 provides up to 216 56Gb/s full bi-directional bandwidth per port.

The SX6512 can scale as the number of nodes per cluster and the number of cores per node increase. This modular chassis switch provides an excellent price-performance ratio for medium to extremely large size clusters, along with the reliability and manageability expected from a director-class switch.
