GAI-ERSR-70B
Series: GAI
The Avalue GAI-ERSR-70B is a 19" 4U GenAI rackmount workstation built around the Avalue HPM-ERSUA server board with a single Intel® Xeon® Silver 4514 (or above) processor and Intel® C741 chipset, pre-integrated with 4 x NVIDIA RTX 4000 Ada (20GB/130W) GPUs for on-premise large-model generative-AI inference. With 576GB DDR5 RDIMM, a 4TB M.2 NVMe OS drive, a 1300W ATX PSU and IPMI 2.0 via an ASPEED AST2600 BMC, it ships as a ready-to-run Open WebUI LLM appliance sized for ~70B-class models, in a 430 x 174.8 x 528 mm chassis. It provides 4 x PCIe Gen5 x16 and 3 x PCIe Gen5 x4 slots, triple Intel Ethernet (I210AT 1GbE, I226-LM 2.5GbE, X550AT2 dual 10GbE), USB 3.2 Gen1/USB 2.0 and VGA, running Ubuntu 22.04 LTS.
