GIGABYTE G494-ZB1-AAP2 4U Dual Socket SP5 GPU server barebone para AMD EPYC 9004, 12x 2,5 polegadas NVMe/SATA/SAS, 8x PCIe Gen5 x16, 2x 10GbE, 4x 3000W Titanium PSU

The G494-ZB1-AAP2 stands apart from conventional GPU servers by pairing dual AMD EPYC 9004 sockets with eight double-width PCIe Gen5 x16 slots in a 4U chassis, delivering uncompromised bandwidth for AI training, HPC, and virtualization clusters. Its tool-less design and hot-swappable components reduce maintenance windows, while the 3+1 redundant 3000W Titanium power supplies ensure continuous operation under full load.

Highlights

• Dual Socket SP5 for AMD EPYC 9004 Series processors, up to 400W TDP per socket
• 24 DDR5 DIMM slots (12 per CPU), supporting up to 6TB of memory at 4800MHz
• 8x PCIe Gen5 x16 double-width slots for high-performance GPUs or accelerators
• 12 front hot-swap 2.5" bays for NVMe/SATA/SAS, plus 2 rear hot-swap bays
• Dual 10GbE LAN via Intel X710-AT2, dedicated management port, and ASPEED AST2600 BMC
• 4x 3000W 80 PLUS Titanium redundant PSUs (3+1) and 8 hot-swap system fans

In daily use

Deploying this barebone is straightforward: install your chosen EPYC 9004 CPUs, populate the DDR5 slots, and slide in up to eight GPUs. The front drive bays support high-speed NVMe for caching or scratch space, while the rear bays handle boot drives. The dual 10GbE ports provide ample network throughput for clustered workloads, and the dedicated management port allows remote monitoring and control via IPMI 2.0, even when the OS is down.
