Switch-IB, the seventh generation switching IC from Mellanox, is the base IC for the company’s first EDR switching solutions with industry-leading bandwidth, low-latency, and scalability. The integration of 144 SerDes, which can operate at 1 Gb/s to 25 Gb/s speeds per lane, makes Switch-IB an obvious choice for OEMs that must address end-user requirements for faster and more robust applications. Reduced power and footprint and a fully integrated PHY capable of connectivity across PCBs, backplanes as well as passive and active copper/fiber cables allow interconnect fabrics based on Switch-IB to be utilized by network architects deploying leading, fabric-flexible computing and storage systems with the lowest total cost of ownership.

The integrated InfiniBand routing functionality enables design and deployment of larger scale InfiniBand fabrics.
