Dual-processor barebone for AI/HPC
This 2U rackmount barebone accepts two 4th or 5th Generation Intel Xeon Scalable processors or Xeon CPU Max Series in LGA 4677 sockets. The Intel C741 chipset provides eight memory channels per CPU, giving 32 DDR5 5600 RDIMM slots in total. No CPUs or memory are installed, so the builder selects exact core counts and capacities.
Suits GPU-heavy AI training.
The chassis fits two full-height full-length dual-slot Gen5 GPU cards plus additional Gen5 add-in cards, making it appropriate for model training and HPC workloads. Builds that only need basic compute or a single processor will leave much of the PCIe and memory capacity unused, so a smaller single-socket platform would be more practical.
12 front hot-swap bays for NVMe/SATA/SAS
Twelve 2.5-inch drive bays connect to PCIe Gen4 lanes and support NVMe, SATA and SAS devices in any mix. This density lets a single 2U node hold high-capacity flash arrays or balanced hot/cold tiers without external enclosures.

Questions about this item
What PCIe generation do the two full-height GPU slots use, and what bandwidth does that limit each card to?
The two full-height GPU slots are PCIe Gen5 x16, so each card is limited to the Gen5 x16 bandwidth ceiling.
What rail depth and rear clearance does the 2U chassis need for the dual 350 W processors and full-length GPU cards?
The 2U rackmount chassis requires standard 2U rail depth plus enough rear clearance for full-height, full-length Gen5 GPU cards and dual 350 W CPU coolers.
In what order should the two LGA 4677 Xeon processors and 32 DDR5 5600 RDIMMs be installed to avoid the common mis-seating error?
Install both LGA 4677 processors first, then populate all 32 DDR5 5600 RDIMM slots evenly across the eight channels per CPU to avoid the common channel-imbalance mis-seating.
