Context Before

Scale-Up Network – NVLink 6

The bidirectional SerDes technology employed on the copper backplane is used for NVIDIA’s scale-up network. For Vera Rubin NVL72, the scale-up network continues to be rail-optimized with all-to-all connectivity between each GPU and switch ASIC in the scale-up domain.

Evidence

Last year, we discussed NVIDIA’s GB200 scale-up architecture, which consists of 18 NVLink 5 Switch chips in a single rack for the NVL72 system.

Context After

GB200 Hardware Architecture - Component Supply Chain & BOM

② Atomic Claim

NVIDIA 的 GB200 scale-up architecture，在單一 NVL72 rack 中包含 18 顆 NVLink 5 Switch chips。

③ Semantic Frame

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
vendor	NVIDIA	NVDA
platform	GB200	GB200
switch_interconnect	NVLink 5	NVLink5

⑤ V2 Draft（需要修正時直接編輯）

Inline repair

只編輯以下三個 Draft 區塊。完成後將 review_action 設為 REQUEST_REPAIR，再手動執行 Repair Preview。
執行腳本前，Draft 不會寫入 Claim Store 或 Graph。

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
