VR2R-0621

① SA Source

Context Before

The first reason is that a significant amount of power can be saved by eliminating most of the transceiver content. If we compare the power consumption of one 800G DR4 optical transceiver (16-17W) to the power required by optical engines (OEs) and

Evidence

external light source (ELS) modules to deliver an equivalent 800G of bandwidth in the scale-out network, we see an average ~70% reduction in power used for optical transceivers.

Context After

Taking a step back, this would translate to 10% in savings for the total networking equipment power consumption in a 3-Layer HGX Rubin NVL8 cluster. This reduction in networking equipment power consumption is however relatively insignificant and amounts to only ~1% of total cluster power consumption because the server’s power budget dominates the equation.

② Atomic Claim

……再加上 external light source(ELS)modules,若提供等效 800G scale-out bandwidth,optical transceiver power 平均可降低約 70%。
