Context Before
The details below are based on the Rubin Kyber prototypes, but Rubin Ultra will be redone.
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.
Context After
The GPUs are connected all-to-all to the switch blades via 2 PCB midplanes or 1 midplane per canister.
② Atomic Claim
每個 switch blade 的高度也比 GTC 2025 prototype 增加一倍；每個 switch blade 配置 6 顆 NVLink 7 switch，每個 rack 有 12 個 switch blade，因此每個 Kyber rack 總共有 72 顆 NVLink 7 switch。
