High-density 2U 4-node server barebone

The GIGABYTE H273-Z81-AAW1 is a 2U rackmount chassis housing four independent dual-socket nodes. Each node accepts two AMD EPYC 9004 or 9005 series processors in SP5 sockets with cTDP up to 240W, or 300W with a low-profile card at 30°C ambient. The system targets high-density compute clusters and virtualization farms that need maximum throughput in minimal rack space.

Suited for integrators building Gen5-ready clusters

This barebone suits builders who populate their own CPUs, DDR5-4800 RDIMMs across 96 slots, and storage across eight 2.5-inch Gen4 NVMe/SATA/SAS hot-swap bays plus four M.2 slots. It is not for buyers wanting a pre-configured system with processors or memory installed, nor for workloads needing GPU acceleration beyond the eight low-profile PCIe Gen5 x16 slots and four OCP NIC 3.0 Gen5 x16 slots provided.

Dual-socket SP5 nodes with 12-channel DDR5

The defining specification is the dual AMD EPYC SP5 socket design per node delivering twelve memory channels and support for DDR5-4800 registered DIMMs up to 24 per node. This architecture determines whether your processor selection, memory capacity plan, and PCIe Gen5 lane budget align with the platform.

Questions about this item

Will the 2U 4-node chassis accept the DDR5 4800 RDIMMs I already own for my current EPYC 9004 servers?

Yes, each node provides 24 DDR5 4800 RDIMM slots across 12 channels, so your existing DDR5 4800 registered modules are compatible.

How can I verify that all four nodes are operating correctly after I install CPUs, memory and drives?

Each node has a power button with LED, an ID button with LED, a reset button and a system status LED; the chassis also includes a CMC status LED and CMC reset button for overall monitoring.

What components are included with the barebone and which items must I purchase separately?

The unit ships as a 2U 4-node chassis with 8 x 2.5" Gen4 NVMe/SATA/SAS hot-swap bays, 4 x M.2 slots, 8 x LP PCIe Gen5 x16 slots, 4 x OCP NIC 3.0 slots and 8 x 1Gb/s LAN ports; CPUs, DDR5 4800 RDIMMs and storage drives are not included.
