AI Fabric Spine-Leaf 計算器
將 GPU 伺服器連線換算為可核對的 Leaf、Spine、Pod 與介質規劃，並區分實體籠口與邏輯拆分埠。
計算結果
計算方式
求解器依 pooled 或 rail 模式配置端點，枚舉完整實體籠口的上下行分配，再檢查超售、Spine radix、Pod 上限與單 Spine 故障容量。
oversubscription = (D × endpoint rate) ÷ (U × uplink rate)
規劃界線
此結果不是可直接下單的 BOM；breakout、光模組、線距、韌體、電力、散熱及 SKU 仍須由供應商確認。
平台依據
規格與供貨標籤來自連結的原廠資料；容量統一採單向線速。
