Overview
The Aivres KR5288 is a 5U liquid-cooled AI server built on the NVIDIA HGX B200 8-GPU platform, with support for Blackwell Ultra (HGX B300) as well. Direct-to-chip liquid cooling covers the GPUs, both CPUs and the NVSwitch fabric, which lets a 5U chassis carry eight 1000 W GPUs and two 500 W EPYC 9005 processors.
The platform is fully modular: GPU baseboard, CPU modules and NVSwitch are separate assemblies, so field service and upgrades do not require stripping the whole chassis. Networking is eight NVIDIA ConnectX-8 SuperNICs.
In a rack configuration, eight KR5288 servers make up 64 B200 GPUs with a vertical coolant manifold at the rear carrying 24 outlets and 48 hoses, a reference design for direct-liquid-cooling AI halls.
Key Benefits
8 × HGX B200/B300 with NVLink and NVSwitch; direct-to-chip liquid cooling on GPU, CPU and NVSwitch; 5U high performance density; dual AMD EPYC 9005 up to 500 W TDP per socket; modular GPU/CPU/NVSwitch assemblies for serviceability.
Applications
Large language model training and inference up to 400B parameters, generative AI, HPC simulation, and rack-scale liquid-cooled AI factory clusters.
