Lambda, the Microsoft-backed neocloud, has given the world a glimpse at Nvidia’s upcoming co-packaged optics (CPO) networking switches after it was given early access.
With the hardware in “full production” ahead of an anticipated release later this year, Lambda was given an early look to try it out for use in its GB300 NVL72 systems.
The neocloud was given a Quantum-X Q3450-LD switch – the InfiniBand-based offering – which comes in a 4U form factor, housing 144 x 800G ports. It offers up to 115.2 terabits per second (Tbps) of non-blocking switching capacity. The switch is liquid-cooled, with four UDQ4 liquid cooling connections via dual internal loops.

Nvidia’s embrace of silicon photonics sees it look to boost bandwidth demands and improve connectivity between servers in mammoth GPU clusters.
