Dell PowerEdge XE7745

The Dell PowerEdge XE7745 is a 4U dual-socket, air-cooled AI server built around PCIe accelerators, aimed at AI inferencing, model fine-tuning and AI-powered HPC. It holds up to eight double-wide 600W PCIe Gen5 GPUs, such as the NVIDIA H200 NVL, H100 NVL, RTX Pro 6000 or AMD MI350P, or up to sixteen single-wide 75W cards like the L4. Two 5th Gen AMD EPYC 9005 processors with up to 192 cores each drive 24 DDR5 RDIMM slots for up to 3TB at up to 6400 MT/s. Eight more front PCIe Gen5 x16 slots serve cluster networking, alongside an optional OCP 3.0 card, up to 8x E3.S Gen5 NVMe SSDs and BOSS-N1 boot. Hot-swap fans, Titanium 3200W or 2400W PSUs in separate CPU and GPU zones and iDRAC10 round it out. Fully configurable.
