Dual Xeon 8562Y+ AI server

This 4U rack system pairs two 32-core Xeon 8562Y+ processors at 2.80 GHz with 1 TB of DDR5-5600 memory. It targets organisations running large-scale AI training, inference or high-performance computing workloads that need dense GPU acceleration in a single chassis.

Upgrade from smaller GPU clusters

The server installs eight NVIDIA L40S PCIe cards alongside dual 100 GbE QSFP56 networking and 2 x 1.92 TB U.2 plus 1 x 960 GB M.2 NVMe storage. The jump makes sense when a workload saturates fewer GPUs or when memory capacity limits model size on existing nodes.

Rack integration and service notes

Four 2700 W Titanium power supplies and eight hot-swap fans support redundant cooling and power. Front-access 2.5-inch NVMe and SATA bays plus two M.2 slots allow drive changes without removing the chassis, though the 4U height and GPU weight demand a sturdy rack and careful cable routing.

Questions about this item

What rack height and front drive-bay clearance does this 4U server need?

The chassis occupies 4U and provides 8 front hot-swap 2.5" NVMe bays plus 8 front hot-swap 2.5" SATA bays, so the rack must accommodate that bay depth.

How are the eight NVIDIA L40S GPUs installed, and which step is often missed?

The GPUs mount in the PCIe expansion slots; the step often missed is connecting each card's auxiliary power cables from the 2700W Titanium supplies before closing the chassis.

Which fan modules will need replacement over time, and how many are there?

Eight hot-swap heavy-duty fan modules provide cooling; any module can be replaced individually while the system runs.
