Context Before

While there are both InfiniBand and Spectrum-X based clusters, the InfiniBand-based Quantum X800-34XX series of switches is more popular with Neoclouds than with hyperscalers. For InfiniBand, there are two deployment types—the first is the Quantum X800-Q3400 with pluggable optics and the second is the Quantum X800-Q3450 CPO-based switch that use co-packaged Optical Engines (OE) instead of pluggable transceivers.

Evidence

The Quantum X800-Q3400 is logically a multi-plane switch combining 4 Quantum-3 ASICs into a single switch box.

Context After

This multi-plane “topology” is abstracted away and as far as network engineers are concerned, the Q3400 is a single switch with 144 ports—or a “little boy” switch.

② Atomic Claim

Quantum X800-Q3400 在 logical 上是一個 multi-plane switch，把 4 顆 Quantum-3 ASICs 整合在單一 switch box 內。
