News Dell will have an eight-way Nvidia Blackwell server with liquid cooling — coming later this year

Interestingly, Dell and Nvidia call the Dell PowerEdge XE9680L server 'one of industry's densest, energy-efficient rack-scale solutions for large Blackwell GPU deployments.'

Yeah. Not surprising though, since it comes in the compact 4U form factor, industry’s highest density x86 server solutions. Most likely candidate is obviously next-gen NVIDIA HGX B200.

Pretty sure the 'L' means liquid cooling here, since XE9680L leverages direct liquid cooling/DLC smart cooling for both CPUs and GPUs. Btw, DELL claims customers can scale up to 72 Blackwell GPUs per 52 RU rack, or 64 GPUs per 48 RU rack.

Also, it appears that while XE9680 has 10 PCIe Gen 5 FHHL slots, this "L" variant has 12 PCIe Gen 5 FHHL slots, so that means 2x capacity for high-speed I/O for North/South AI fabric as well (if we consider a config of 8 PCIe Gen 5 FHHL slots 1:1 allocated to the 8 GPUs in the XE9680 and XE9680L).
