Context Before

Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗

Evidence

Because there is only 1 DP per lane using bidirectional SerDes, there are a total of 18 DPs between any connector and any switch for a total of 72 DPs per connector, which is the same as prior generation of NVLink 5 Switch Tray

Context After

Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗

② Atomic Claim

因 bidirectional SerDes 每 lane 只需 1 DP，因此任一 connector 與任一 switch 間共有 18 DPs，每個 connector 共 72 DPs，與前代 NVLink 5 Switch Tray 相同。

⑤ 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
