4U GPU barebone for HPC and AI

This 4U barebone server is built for high-performance computing and artificial intelligence workloads. It supports up to eight dual-slot Gen5 GPU cards in a dual-processor layout. The platform targets research labs and enterprises that need dense GPU acceleration for training, inference and visual computing.

Check CPU, memory and GPU compatibility before

Verify that your chosen 4th or 5th Gen Intel Xeon Scalable processors or Xeon CPU Max Series parts fit the LGA 4677 socket. The board provides eight-channel RDIMM DDR5 across thirty-two DIMM slots, so populate memory in matched sets per channel. Ensure each GPU is a dual-slot Gen5 design and that your power budget covers eight cards plus both CPUs.

Sustained load relies on chassis airflow

Under continuous HPC or AI training the eight GPUs and dual CPUs generate substantial heat; the 4U enclosure must supply enough front-to-rear airflow to keep all components in spec. Stable operation also depends on the installed power supplies delivering clean current to every GPU slot and CPU socket without throttling.

Questions about this item

Which processors, memory modules and GPU cards must be purchased separately to complete this G493-SB2-AAP1 barebone?

The barebone supplies the chassis, motherboard with dual LGA 4677 sockets, 32 DDR5 DIMM slots and eight dual-slot Gen5 GPU bays; you must add two Xeon Scalable CPUs, up to 32 RDIMM DDR5 modules and up to eight compatible GPU cards.

How do I decide between 4th Gen Xeon, 5th Gen Xeon and Xeon CPU Max Series for this dual-socket server?

Choose 5th Gen Xeon for the highest per-core performance, 4th Gen Xeon for a lower acquisition cost, or Xeon CPU Max Series when the workload benefits from on-package high-bandwidth memory; all three families fit the same LGA 4677 sockets.

What does the eight dual-slot Gen5 GPU capacity mean for a real HPC or AI training deployment?

It lets you install eight full-length, dual-slot Gen5 accelerators simultaneously, delivering maximum GPU density in a 4U form factor for large-model training or parallel simulation workloads.
