NVIDIA CS7500 InfiniBand Switch Series

Switch-IB 2 EDR 100Gb/s InfiniBand Smart Director Switches

Today’s massive growth of data and real-time data processing demand faster, more efficient interconnects for high-performance computing (HPC), cloud, and hyperscale data centers. NVIDIA® Mellanox® CS7500 switches deliver low latency and 100Gb/s of bandwidth in an up to 28U chassis, with assured bandwidth and granular quality of service. The CS7500 series’ innovative capabilities provide high system performance, scalability, and the best network utilization.

Scaling out Data Centers

The NVIDIA Mellanox CS7500 series of smart director switches provides up to 648 enhanced data rate (EDR) 100Gb/s ports—enabling a high-performing fabric solution for HPC, AI, cloud, and hyperscale data center infrastructures in an up to 28U form factor. Its smart design provides unprecedented levels of performance and simplifies the building of clusters that can scale out to thousands of nodes. Moreover, the leaf blades, spine blades, management modules, power supply units (PSUs), and fan units are all hot-swappable, eliminating downtime.
