1U Rack Server for General Purpose Workloads

The Supermicro AS -1125HS-TNR-G1 is a 1U rack server built for general purpose workloads. It ships with a single AMD EPYC 9454P 48-core processor running at 2.75 GHz and 256 MB of L3 cache. The system includes 384 GB of DDR5-5600 memory across 24 slots and a 960 GB U.2 NVMe SSD. Eight hot-swap counter-rotating fans provide cooling in a compact chassis.

Upgrade from Single-Socket or Lower-Core Platforms

This server replaces older single-socket systems or dual-socket configurations with fewer total cores. The jump is worth it when workloads demand 48 cores and 384 GB of DDR5 memory in a 1U form factor. Support for a second EPYC 9004 series processor allows scaling to 96 cores without changing chassis. Memory capacity can grow to 6 TB using ECC DDR5 RDIMMs at 4800 MT/s.

Suits Density-Focused Compute.

This platform suits buyers who need high core count and large memory in a single rack unit for virtualisation, databases or HPC head nodes. It is not for buyers who require GPU acceleration, as the 1U height and fan layout do not support full-height add-in cards. Builders needing more than two U.2 NVMe drives or front-loading storage bays should look at larger chassis designs.

Questions about this item

What rack depth and clearance does the 1U chassis with 8 counter-rotating 40x40x56mm fans need?

The 1U rack height fits a standard 19-inch rack; allow space front and rear for the 8 hot-swap 40x40x56mm counter-rotating fans to draw and exhaust air without obstruction.

Which CPU socket preparation step is most often missed when installing the single EPYC 9454P on the SP5 platform?

Install the AMD EPYC 9004 series processor into the SP5 socket using the correct torque sequence and load-plate orientation; skipping the specified torque pattern can cause uneven contact and boot failure.

When do the 24 DDR5-5600 RDIMM slots require battery-backed NVDIMM or standard ECC RDIMM replacement?

Replace ECC DDR5 RDIMMs only when the BMC logs correctable-error thresholds or a module fails POST; the 24 slots support up to 6TB at 4800 MT/s with EPYC 9004 or 6000 MT/s with EPYC 9005.
