InfiniBand provides the highest bandwidth, lowest latency, and most scalable interconnect for servers and data storage. InfiniScale IV, the fourth generation switching device from Mellanox, improves these leading attributes further, making Mellanox InfiniBand an obvious choice for the most demanding applications. Switch systems based on InfiniScale IV can be used by network architects to construct Petascale computing systems. IT managers can build large networks that carry converged traffic with the best combination of assured bandwidth and granular quality of service.
