Evidence
Each switch blade is also double in height vs the GTC 2025 prototype, with 6 NVLink 7 switches per switch blade, and 12 switch blades per rack, amounting to a total of 72 NVLink 7 switches per Kyber rack. The GPUs are connected all-to-all to the switch blades via 2 PCB midplanes or 1 midplane per canister.
Context After
Kyber midplane PCB (GPU side). Source: Nvidia, SemiAnalysis
② Atomic Claim
In the March 2026 Kyber prototype/design discussion: Kyber 的 GPU-to-switch-blade 連線透過 2 片 PCB midplane，等價於每個 canister 1 片 midplane。
