Context Before
In multi-plane network architectures using the SN6600 switch instead of the CPO switch, each GPU fans out to multiple switch boxes using fiber shuffles.
Evidence
This requires customers to deploy shuffle boxes, patch panels and unwieldy octopus cables outside the switch box that introduce complexity in installation and maintenance.
Context After
Some of Nvidia’s CPO SKUs—such as the SN6800 and Q3450—contain such a fiber shuffle within the switch box, with each optical engine fanning out to different logical ports. They therefore deliver higher aggregate bandwidth—409.6T and 115.2T respectively—than is possible with a switch box based on a single Switch ASIC.
② Atomic Claim
這種架構要求客戶在 switch box 外部署 shuffle boxes、patch panels 與難以管理的 octopus cables，增加安裝與維護複雜度。
