2U liquid-cooled AI server
The Dell PowerEdge XE9640 is a 2U rack server built for AI, ML, DL and HPC workloads. It supports up to two Intel Xeon Scalable processors on the Intel C741 chipset and ships without CPUs or memory installed. The chassis uses liquid cooling to handle high-density accelerator configurations.
Sustained accelerator performance
The system accommodates four Intel Data Center Max 1550 OAM modules at 600 W each with Xe Link, or four NVIDIA H100 SXM modules at 700 W each with NVLINK. Liquid cooling is designed to maintain thermal stability for these accelerators during continuous training or inference runs. Front bays accept up to four 2.5-inch NVMe SSDs for a maximum of 61.44 TB of high-speed local storage.
Pre-deployment checklist
Verify that your rack provides 2U of space and compatible liquid-cooling infrastructure for the chosen GPU option. Confirm DDR5 memory module quantities: 16 or 32 DIMMs for NVIDIA configurations up to 2 TB, but only 16 DIMMs supported for Intel GPU configurations up to 1 TB. Ensure power distribution can deliver the required wattage for dual CPUs plus four 600 W or 700 W accelerators.

Questions about this item
How much heat does the liquid-cooled server produce when running AI workloads all day?
The server uses liquid cooling to handle four GPUs rated at 600 W or 700 W each, keeping component temperatures stable under continuous load.
Which CPUs and memory must I supply to make the system operational?
You must install up to two Intel Xeon Scalable processors on the C741 chipset and populate DDR5 DIMMs up to 2 TB total capacity.
Can I keep my existing SATA or SAS drives and use them in the front bays?
The front bays accept up to four 2.5-inch NVMe SSDs only; SATA and SAS drives are not supported in those slots.
