SX6518 324-Port InfiniBand Director Switch


The SX6518 switch system provides the highest-performing fabric solution in a 16U form factor by delivering 36.3Tb/s of non-blocking bandwidth with sub 1µ port latency.

Built with Mellanox’s 5th generation SwitchX® InfiniBand switch device, the SX6518 provides up to 324 56Gb/s full bi-directional bandwidth per port.

The SX6518 can scale as the number of nodes per cluster and the number of cores per node increases. 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.
