Silver 2U rack chassis with four rear-access server nodes and eight hot-swap drive bays

GIGABYTE

GIGABYTE H273-Z81-AAN1 barebone server 2U 4-node AMD EPYC 9004 8-bay 2600W

SKU CH-745T-S8SQS MPN H273-Z81-AAN1

A 2U four-node barebone server supporting dual AMD EPYC 9004 processors per node with 24 DDR5 DIMM slots, eight 2.5-inch NVMe/SATA/SAS bays and a 2600W power supply

  • 2U chassis fits four independent compute nodes for maximum rack density
  • Dual AMD EPYC 9004 processors per node deliver high core-count performance
  • 24 DDR5 RDIMM slots per node support large memory capacity
  • Eight 2.5-inch hot-swap bays handle Gen4 NVMe SATA SAS drives
  • Eight low-profile PCIe Gen5 x16 slots provide extensive expansion bandwidth

High-density 2U 4-node server

The GIGABYTE H273-Z81-AAN1 is a 2U barebones system housing four independent compute nodes. Each node supports dual AMD EPYC 9004 series processors and 24 DDR5 RDIMM slots across 12 memory channels. It targets deployments that need maximum core density in a compact rack footprint.

Shared 2600W power with rear access

A single 2600W power supply feeds all four nodes through a rear-access design that simplifies maintenance. Eight 1Gb/s LAN ports via Intel I350-AM2 provide baseline connectivity for each node. The architecture consolidates power and cooling for the dense configuration.

Eight 2.5-inch Gen4 NVMe/SATA/SAS bays

The chassis provides eight hot-swap drive bays supporting Gen4 NVMe, SATA and SAS devices. Four optional M.2 slots with PCIe Gen4 x4 interface add further storage flexibility. Buyers needing more than eight front bays per 2U enclosure should evaluate alternative platforms.

Questions about this item

How are the AMD EPYC 9004 processors installed in each node, and which step is often missed?

Each node takes two EPYC 9004 CPUs; the step often missed is fully seating both processors before locking the retention frames, because the 12-channel DDR5 layout leaves little clearance for later adjustment.

Which components in the H273-Z81-AAN1 will need replacement first under continuous operation?

The 2600 W power supply units and the cooling fans are the first parts that typically require replacement during sustained 24/7 use.

What thermal or power limit appears first when all four nodes run sustained workloads?

The shared 2600 W power budget across four dual-socket nodes is the first constraint reached under heavy sustained load.
