2U dual-socket GPU barebone

The ASUS ESC4000-E11-26WGP is a 2U rackmount barebone designed for dual 5th Gen Intel Xeon Scalable processors. It provides 16 DDR5 DIMM slots running at 4800 or 4400 MT/s and supports up to four dual-slot GPUs with NVLink bridge capability. Six front drive bays accept Tri-Mode NVMe, SATA or SAS storage for high-throughput workloads.

Independent airflow tunnels and Titanium PSU

Separate CPU and GPU airflow tunnels optimise thermal performance under sustained AI and HPC loads. Two 2600W 80 Plus Titanium redundant power supplies deliver uninterrupted operation. The design targets power-efficient operation while handling processors rated up to 350W and multiple high-power accelerators.

Remote management and expansion flexibility

The ASMB11-iKVM module with ASPEED AST2600 enables out-of-band control and hardware-level security. A rear PCIe 5.0 slot accommodates high-speed networking modules, and ASUS Control Center software simplifies infrastructure management. Buyers needing more than four GPUs or more than six NVMe bays will require a larger platform.

Questions about this item

How do I install CPUs and memory in the ESC4000-E11-26WGP, and which step is most often missed?

Fit both 5th Gen Xeon processors first, then populate the 16 DDR5 288-pin slots following the silkscreen channel order; the step most often missed is enabling the correct memory speed — 4800 MT/s at 1 DPC or 4400 MT/s at 2 DPC — in the BIOS after the first boot.

What maintenance or replacement will the ESC4000-E11-26WGP need over time?

The dual 2600W Titanium power supplies are hot-swap redundant; plan to replace a failed unit without downtime. System fans and the front NVMe/SATA/SAS drive bays are also field-replaceable, while the ASPEED AST2600 BMC firmware should be updated periodically via the management port.

What limit appears first when the ESC4000-E11-26WGP runs sustained AI workloads?

Thermal headroom for up to four dual-slot GPUs is the first constraint; the independent CPU and GPU airflow tunnels and dual 2600W PSUs are designed for continuous operation, but GPU power draw and case temperature will throttle clocks before the power supplies or PCIe 5.0 bandwidth are saturated.
