At OCP Global Summit 2026 in San Jose, we stopped by the Aivres booth. The lineup featured a lot of NVIDIA, spanning a Vera Rubin NVL72 rack down to a PCIe GPU server, with an HGX Rubin NVL8 tray, Vera CPU hardware, and an HGX B300 server in between.
We saw the Aivres Vera Rubin rack at its NVIDIA GTC 2026 booth, so this was a chance to see more of the hardware around it.
Aivres KRS8000V4 NVIDIA Vera Rubin NVL72 Rack
The big rack at the booth was the Aivres KRS8000V4, the company’s NVIDIA Vera Rubin NVL72 liquid-cooled AI rack. At the show, this was a mix of dummy blanks and a live node. These racks are rough to transport to trade shows, but we have seen them many times before.
Aivres lists 18 1U compute trays and nine 1U NVLink switch trays, as shown above, with the switch trays in the middle and power shelves at the top and bottom. That is 72 Rubin GPUs and 36 Vera CPUs on sixth-generation NVLink. That creates a giant GPU domain over NVLink with over 20TB of HBM. Aivres says this is 100% liquid-cooled and can operate at 45C to help cooling efficiency. A hot tub is usually 38-39C, so that gives you an idea of how warm the fluid is in the rack.
With eighteen compute trays, plus switch trays, management switches, an integrated NVLink…
