ASUS ESC4000A-E12-26WGPT barebone server 12 DDR5 6 NVMe 2600W

AMD EPYC 9004/9005 AI Server Barebone

This 2U barebone server supports a single AMD EPYC 9004 or 9005 processor with up to 128 Zen 4c cores and a 400W TDP. It targets organisations deploying AI training, inference or HPC workloads that need dense GPU compute in a compact rack footprint. The platform delivers 12-channel DDR5 memory architecture and full PCIe 5.0 connectivity for high-throughput data pipelines.

Upgrade from single-GPU or CPU-only platforms

The jump is worth it when workloads demand four dual-slot GPU accelerators with NVLink bridge support and eight PCIe 5.0 expansion slots. Systems limited to fewer GPUs, older PCIe generations or single-socket CPUs without 12-channel memory bandwidth will see measurable scaling for large-model training and data-analytics clusters. Buyers who need more than four GPUs or dual-socket CPU configurations should evaluate larger chassis options.

12 DDR5 slots and six Tri-Mode NVMe bays

The 12 DIMM slots support up to 3TB of DDR5-4800 ECC registered memory, providing headroom for memory-intensive models and in-memory databases. Six hot-swap Tri-Mode bays accept NVMe, SATA or SAS drives for flexible all-flash or hybrid storage tiers. Dual 2600W 80PLUS Titanium redundant power supplies sustain full GPU and CPU loads, while the ASMB11-iKVM BMC enables remote management. Workloads requiring more than 3TB memory or more than six front drive bays exceed this platform's capacity.
