Context Before

Nvidia provided a long-awaited update on its Kyber rack form factor, the latest addition to the lineup after Oberon having first been previewed as a prototype at GTC 2025. As a prototype, the rack architecture has continued to evolve, and we notice some changes.

Evidence

First, each compute blade has densified, with 4x Rubin Ultra GPU and 2x Vera each.

Context After

There are a total of 2 canisters of 18 compute blades which amounts to 36 compute blades total for 144 GPUs in a rack.

② Atomic Claim

首先，每個 compute blade 的密度提高，配置 4 顆 Rubin Ultra GPU 與 2 顆 Vera。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
platform	Rubin Ultra	04_knowledge_base/Rubin Ultra
compute_device	GPU	GPU

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
• 最後選擇 review_action
