Meta unveils liquid-cooled 102.4T IcePack/IceCube network racks at OCP Summit

The racks cover scale-up, scale-out and scale-across, supporting the Prometheus cluster that trains Muse Wonder and Muse Spark.

Liquid cooling for network gear, not just GPUs, reflects the thermal density of 800G fabrics. Dual-vendor switch silicon hedges supply risk.

Watch whether Meta open-sources the designs through OCP.
