Evidence

From each switch tray, rear-facing ports connect to that copper spine for intra-rack communication

Context After

Networking within the rack uses a Spectrum-X multiplane topology, distributing 200 Gb/s lanes across the four switches to achieve full all-to-all connectivity while maintaining a single network tier. With each compute tray housing 8 Vera CPUs, the result is 256 CPUs per rack, all interconnected over Ethernet through a single, flat network.

② Atomic Claim

每個 switch tray 的後方 ports 連到 copper spine，負責機櫃內通訊。
