Context Before

Source: SemiAnalysis

Each Vera ETL rack consists of 32 compute trays, 16 above and 16 below, arranged symmetrically around four 1U MGX ETL switch trays (based on Spectrum-6) in the middle. The symmetric split is deliberate: it minimizes cable length variance between compute trays and the spine, keeping all connections within copper reach. From each switch tray, rear-facing ports connect to that copper spine for intra-rack communication, while 32 front-facing OSFP cages provide optical connectivity to the rest of the POD.

Evidence

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

② Atomic Claim

機櫃內網路採 Spectrum-X multiplane topology,將 200 Gb/s lanes 分散到 4 顆 switches,在維持單一 network tier 的同時實現完整 all-to-all connectivity。
