Context Before

Unlike the BF-4 in the VR NVL72, which consists of a Grace CPU and a single CX-9 NIC, the BF-4 in the STX reference design includes one Vera CPU, two CX-9 NICs, and two SOCAMM modules. Each STX box contains two BF-4 units, totaling two Vera CPUs, four CX-9 NICs, and four SOCAMM modules.

Evidence

For the whole STX rack, it has a total of 16 boxes, implying 32 Vera CPUs, 64 CX-9 NICs, and 64 SOCAMMs.

Context After

② Atomic Claim

整個 STX rack 有 16 個 box，因此推算共有 32 顆 Vera CPU、64 顆 CX-9 NIC 與 64 個 SOCAMM。

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
