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
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 compute tray 配置 8 顆 Vera CPUs,因此每櫃共 256 顆 CPUs,並透過單一 flat network 以 Ethernet 全部互連。
