① SA Source

Context Before

Source: SemiAnalysis AI Networking Model ↗

The catch is that 102.4T Minipack-4 switches may not be shipped in time for Vera Rubin NVL72 rack deployments, and if this were to be the case, some NSF clusters will be shipped using 51.2T Minipack-3 switches instead. This means that gearboxes within the AECs will have to be used to convert 200G per lane SerDes speed at the NIC to 100G per lane SerDes speed at the switch.

Evidence

Meta will not be the only hyperscaler using 1.6T AECs for its VR200 deployments, however. We think xAI will use 1.6T AECs for both NIC-to-TOR and switch-to-switch connectivity at the leaf, spine and core layers. It will be a single-plane network replacing most 1.6T transceivers at the switch boxes – and this can give Credo plenty of pricing power.

⑥ Human Review

請在 Properties 逐項確認:

  • 原文 → Atomic Claim 是否忠實
  • Atomic Claim → Semantic Frame 是否忠實
  • Canonical Entity mapping 是否正確
  • Epistemic mode 是否保留原文語氣
  • 最後選擇 review_action
