NVIDIA Quantum CS8500 Modular Switch Series

Increase Data Center Availability with HDR 200G infiniBand Smart Switches

Today’s rapid data growth, real-time data processing, and mission-critical application environments fuel demand for faster, more efficient interconnect solutions. The high-density NVIDIA Quantum™ CS8500 switch provides up to 800 ports of HDR 200 gigabits per second (Gb/s) InfiniBand connectivity, enabling high throughput, availability, and scalability.

Streamlining Network Design and Topologies

By implementing NVIDIA port-split technology, the CS8500 switch provides a double-density radix for 100Gb/s (HDR 100) data speeds, reducing the cost of network design and network topologies. Supporting up to 1,600 ports of 100Gb/s, CS8500 is an ultra-dense chassis switch perfect for medium-to-large deployments that require lower power, latency, and space.
