Context Before

Evidence
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
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
上下兩組 compute trays 對稱排列在中央 4 個 1U MGX ETL switch trays 周圍,而這些 switch trays 基於 Spectrum-6。
