Evidence
The symmetric split is deliberate: it minimizes cable length variance between compute trays and the spine, keeping all connections within copper reach
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
這種對稱配置是刻意設計，用來縮小 compute trays 與 spine 之間的 cable length 差異，讓所有連線都維持在 copper 可及距離內。
