NVIDIA Mellanox CS7500 and CS8500 InfiniBand Director Switches - Refurbished, Used, New
This collection carries leaf blades, spine blades, management modules, fan units and power supplies for NVIDIA Mellanox CS7500 and CS8500 InfiniBand director switches, in new and refurbished or used condition. Refurbished and used units are tested before they ship. These are field-replaceable parts for an existing chassis, so start with which director you run.
CS7500 or CS8500: which parts do I need?
The CS7500 is NVIDIA's EDR director: a 28U chassis with up to 648 EDR 100Gb/s InfiniBand ports, built from 36-port QSFP28 leaf blades. The CS8500 is the HDR director: up to 800 HDR 200Gb/s ports (or 1600 HDR100 ports) in a 29U chassis, built from 40-port QSFP56 leaf blades and cooled by a closed liquid loop. NVIDIA lists separate blades and management modules for each director, so order parts that match your chassis.
On the CS7500, NVIDIA offers two generations of blade. The Switch-IB 2 blades (MSB7560-E leaf and MSB7570-E spine) support SHARP in-network computing; the MSB7520-E2 spine blade does not.

What about fans and power supplies?
This page also carries the MTDF-FAN-A and MTDF-FAN-B fan units for the CS7500 and the MTDF-PS-B power supply for the CS8500. NVIDIA lists the MTDF-PS-B as a 3kW AC supply with P2C airflow, which NVIDIA defines as power-side inlet to connector-side outlet. In NetworkTigers terms that is back-to-front (port-side exhaust). NVIDIA lists two fan unit part numbers for the CS7500, so match the part number on the unit you are replacing.
How many power supplies does a chassis use?
NVIDIA ships the CS7500 with 10 power supplies in an N+N configuration. The CS8500 ships with 9 in an N+1 configuration and supports up to 16 for N+N redundancy.
NetworkTigers has supplied enterprise networking equipment since 1996, and every purchase carries a 365-day warranty. For quantity pricing, ask us for a quote.
