Context Before

Some Ethernet-based clusters deployed by hyperscalers will use AECs for NIC-to-TOR and switch-to-switch connections, while

Evidence

other Ethernet-based clusters using only optical interconnects will usually adopt a multi-plane and multi-rail networking architecture.

Context After

What is particularly noteworthy about Vera Rubin NVL72 deployments, however, is that it is the first Nvidia GPU generation where we will be seeing some Co-Packaged-Optics (CPO) deployments in the scale-out backend network.

② Atomic Claim

其他只使用 optical interconnects 的 Ethernet-based clusters，通常會採 multi-plane、multi-rail networking architecture。
