One NVIDIA HGX B300 air-cooled baseboard, with eight 800Gb OSFP connectors for east-west traffic
The Blackwell Ultra generation of Inventec's 10U air-cooled node, in the same 448 by 441 by 850 mm chassis as its B200 sibling but hosted by Intel Xeon 6700 series with E-cores or 6700 and 6500 series with P-cores. It carries one NVIDIA HGX B300 baseboard and eight 800Gb OSFP connectors for east-west networking, one per accelerator. Storage is eight U.2 NVMe bays with four optional more and two M.2. The accelerator power plane moves to 3,300 W supplies in 5+1 redundancy, tighter than the B200 node's 4+2, with a 2,000 W 12 V host plane. Inventec publishes no throughput, memory or system power figure; the linked HGX B300 entry carries NVIDIA's. The GPU count is not stated and is taken from NVIDIA's designation of HGX B300 as an eight-GPU baseboard.
