① SA Source

• Source: 開啟完整 SA 文章
• Section: Ethernet-Based Cluster Deployments
• Line hint: 571

Context Before

• Single plane network with 1.6T OSFP cages at the NIC.

Evidence

For Meta, we think the VR NVL72 deployments will comprise only of non-scheduled fabric (NSF) clusters built using Tomahawk 6-based Minipack-4 OCP Rack 102.4T switches in each datacenter.

Context After

While Meta will be using optics to connect all the switches within its cluster, it will use 1.6T AECs for NIC-to-TOR connections once 1.6T AECs become broadly available in the market. We expect the 1.6T AEC ramp to happen in the second half of calendar year 2026.

② Atomic Claim

SemiAnalysis 認為，Meta 的 VR NVL72 deployments 將只採用 non-scheduled fabric（NSF）clusters，並在每個 datacenter 使用以 Tomahawk 6 為基礎的 Minipack-4 OCP Rack 102.4T switches。
