4U dual-Xeon HGX B200 server

This 4U rack system ships with two Intel Xeon 8570 processors, 2.3 TB of DDR5-4800 memory and an NVIDIA HGX B200 8-GPU baseboard. It targets organisations that need dense GPU compute for large-scale AI training or high-performance analytics.

Suits AI clusters needing eight B200 GPUs in one

Teams that require more than eight GPUs per node, or workloads that run on CPU-only infrastructure, should evaluate alternative configurations. Buyers without 400 Gb/s OSFP networking or 6.6 kW power feeds will also need different hardware.

Deciding spec: eight NVIDIA B200 GPUs on HGX

The installed HGX B200 baseboard provides eight GPUs with 180 GB of video memory and is the single component that determines whether this server matches the target workload. If the application does not need eight B200 GPUs, a different platform will be more appropriate.

Questions about this item

When do the eight B200 GPUs need replacement?

The eight NVIDIA B200 GPUs are soldered to the HGX baseboard and are not field-replaceable; plan on a full baseboard swap when GPU compute capacity no longer meets workload demands

Which component hits its limit first during sustained AI training?

The dual Xeon 8570 processors at 2.1 GHz with 56 cores each will saturate before the 2.3 TB DDR5-4800 memory or the 3.8 TB U.3 NVMe drives under continuous heavy model training

How loud and hot does the 4U chassis get with all eight B200 GPUs running 24/7?

Five hot-swap 60 mm fans and four 6600 W titanium PSUs in 2+2 redundancy move high airflow; expect elevated noise and heat output that requires data-centre cooling infrastructure
