Aivres showed its KRS8000V4 Vera Rubin NVL72 rack and KL2288 HGX Rubin NVL8 compute tray at OCP Global Summit 2026 in San Jose, alongside an HGX B300 server. ServeTheHome’s on-site account described the exhibit; the performance figures attached to the systems are Aivres specifications, not independent benchmark results.

Aivres announced that its showcase was in Booth B3 of the San Jose Convention Center’s Main Expo Hall through October 15, 2026. The company said on October 13 that its showcased AI infrastructure platforms and solutions were available for deployment.

KRS8000V4: a rack-scale Vera Rubin system

Aivres lists the KRS8000V4 with 72 Rubin GPUs and 36 Vera CPUs. ServeTheHome described 18 1U compute trays and nine 1U NVLink switch trays in the rack, along with sixth-generation NVLink and more than 20 TB of high-bandwidth memory (HBM). Aivres describes the rack as fully liquid-cooled.

Aivres lists up to 2.5 EFLOPS of NVFP4 performance for training and up to 3.6 EFLOPS for inference. It separately lists up to 75 TB of rack-local memory. The HBM and rack-local memory figures use different labels.

ServeTheHome reported that the displayed rack included dummy blanks and one live node. The system’s listed performance figures describe vendor specifications, rather than measured results from the exhibit.

KL2288: an eight-GPU, liquid-cooled tray

The KL2288 is a 2U compute tray for NVIDIA HGX Rubin NVL8, with eight Rubin GPUs. Aivres says the platform supports Intel and AMD CPU platforms; the specific unit described at the show used two AMD EPYC 9006 processors, codenamed Venice.

Aivres lists up to 400 PFLOPS of NVFP4 inference performance and 176 TB/s of HBM bandwidth for the KL2288. Figures transcribed from the booth placard also include up to 280 PFLOPS of NVFP4 training performance and 2.3 TB of HBM4 memory. These are vendor-listed specifications.

The on-site description also notes two USB ports, two RJ45 ports and eight E1.S drive bays. The tray has space for an NVIDIA BlueField DPU, OCP rack quick disconnects and a power busbar. Its cooling hardware includes copper CPU cold plates and liquid-cooled DDR5 DIMMs.

ServeTheHome also identified an HGX B300 server among the systems at Aivres’s booth.
