NVIDIA CS8500 InfiniBand Switch Series

Quantum HDR 200Gb/s InfiniBand Smart Modular Switches

Today’s rapid data growth and real-time data processing are fueling the demand for faster, more efficient interconnect solutions. Delivering the modular availability required for mission-critical application environments, the high-density NVIDIA CS8500 switch provides up to 800 high data rate (HDR) 200Gb/s ports, enabling an extremely high-performance, low-latency fabric solution for high-performance computing (HPC), AI, cloud, and hyperscale data center infrastructures.

World-Class Design

CS8500 is an InfiniBand modular switch designed for performance, serviceability, energy savings, and high availability. The leaf blades, spine blades, and management modules, as well as the power supply units (PSUs), are all hot-swappable to help eliminate downtime. CS8500 is an eco-friendly solution cooled solely by a liquid closed loop to reduce noise levels and IT OPEX. CS8500 arrives with liquid coolant (CDU) or air heat exchanger (AHX) data units to best fit all data centers.
