Purpose-built 1U dual-socket server barebones

The GIGABYTE R183-Z94-AAD2 is a 1U rackmount barebones system designed for dual AMD EPYC 9004 Series processors in SP5 sockets. It targets general-purpose workloads that benefit from 5 nm Zen 4 architecture and up to 128 cores per system. Twelve-channel DDR5 memory with twenty-four DIMM slots supports high memory bandwidth for compute-dense deployments.

Suited for dense compute clusters.

This platform fits integrators building 1U dual-socket nodes for virtualization, HPC or cloud workloads where CPU core density and Gen5 NVMe speed matter. Buyers needing more than four hot-swap front bays or onboard networking beyond two 1 GbE ports should evaluate alternative chassis. The dedicated management port and dual ROM architecture simplify remote operations at scale.

Four 2.5″ Gen5 NVMe/SATA/SAS-4 hot-swap bays

The front panel provides four 2.5-inch bays that accept Gen5 NVMe, SATA or SAS-4 drives with hot-swap capability. This single specification determines whether the storage density and interface mix match the intended workload. No additional drive bays or PCIe Gen5 accelerator slots are described in the supplied data.

Questions about this item

What PCIe generation do the four 2.5″ NVMe bays use, and what throughput does that cap?

The four hot-swappable bays run on PCIe Gen5, so each NVMe drive is capped at Gen5 lane speeds rather than the older Gen4 ceiling.

What rack depth and clearance does this 1U dual-socket chassis need to mount?

It fits a standard 1U rack slot; the 12-bay front layout and dual SP5 sockets require enough rear depth for cabling and airflow, but no special rails beyond a typical 1U kit.

How are the 24 DDR5 RDIMM slots populated, and which step do installers often miss?

Each of the two EPYC 9004 CPUs owns 12 channels; populate all 24 slots evenly per CPU, and do not forget to update both ROMs in the Dual ROM Architecture before first boot.
