Version

Quantum-X800 (8th generation InfiniBand switch)

Bandwidth (GB/s, per link, unidirectional)

100

Bandwidth basis

PER LANE, PER DIRECTION. Each XDR 800Gb/s port = 100 GB/s per direction. Switch provides 144 XDR ports.

Link count

144

Topology

Fat-tree, Dragonfly+. 1U fixed-configuration switch.

Scale-up

no

Scale-out

yes

Switching

144 ports of 800 Gb/s per switch. SHARP v4 in-network reduction, adaptive routing, telemetry-based congestion control, performance isolation, low-power link state, power profiling.

notes

Quantum-X800 is the current flagship InfiniBand switch. Product page states 144 ports of 800 Gb/s connectivity per port, SHARP v4, adaptive routing, telemetry-based congestion control. Part of the Quantum-X800 platform with ConnectX-8 SuperNICs. Silicon photonics versions available for reduced power and latency. The switch doubles per-port bandwidth over Quantum-2 while increasing port count from 64 to 144.
