Dual-processor Xeon barebone for GPU compute

The GIGABYTE R283-SF0-AAL1 is a 2U rackmount barebone built for dual 4th- or 5th-generation Xeon Scalable or Xeon CPU Max Series processors up to 350W TDP each. It targets organisations deploying dense AI training, HPC or rendering workloads that need four full-height PCIe Gen5 GPU slots in a compact chassis.

12 hot-swap bays and Gen5 expansion layout

Twelve front-accessible 3.5- or 2.5-inch bays accept NVMe, SATA or SAS-4 drives with hot-swap capability. The board provides four FHFL PCIe Gen5 x16 slots for dual-slot GPUs, one FHHL PCIe Gen5 x16 slot and an OCP NIC 3.0 Gen5 x16 slot for high-speed networking. An Aspeed AST2600 handles baseboard management graphics.

Eight-channel DDR5 memory and dual-ROM firmware

Thirty-two 288-pin RDIMM slots operate in eight channels at up to 5600 MT/s with one DIMM per channel or 4400 MT/s with two. Dual ROM architecture adds firmware redundancy for unattended operation. The platform supports registered DDR5 only and ships without CPUs, memory or storage installed.

Questions about this item

What speed does the PCIe Gen5 x16 interface on the GPU slots actually deliver?

The four FHFL slots and the FHHL slot all run at PCIe Gen5 x16, and the OCP NIC 3.0 slot is also Gen5 x16.

What physical space and power budget must the rack provide for this 2U server?

It occupies a 2U rackmount form factor and supports dual processors with a TDP up to 350W each.

How are the CPUs and memory installed, and what step is often missed?

Install both LGA 4677 processors first, then populate the 32 DDR5 RDIMM slots across the 8 channels; the step often missed is matching the 1DPC or 2DPC configuration to the rated 5600, 4800 or 4400 MT/s speeds.
