1U rackmount storage server barebone

The ASRock Rack 1U8S4E-GENOA/2T is a 1U rackmount barebone designed for storage-intensive workloads. It targets system integrators and IT teams building custom AMD EPYC 9004 series platforms with high drive density. The chassis supports a single Socket SP5 processor up to 300 W and includes a redundant 750 W 80-PLUS Platinum power supply. No CPU or memory is installed.

Tool-less drive bays and passive backplane

Twelve front bays accept 2.5-inch drives through a passive NVMe/SATA/SAS backplane; four bays are wired for PCIe 5.0 x4 NVMe and eight for SATA. SAS drives require an additional RAID or HBA card with cabling. Two internal M.2 M-key slots support PCIe 4.0 x4 lengths from 2230 to 2280. A single full-height half-length PCIe 5.0 x16 slot is available via riser for expansion cards up to 75 W.

Sustained throughput with dual 10GbE

Dual Intel X550-AT2 controllers provide two RJ45 ports at 10 Gigabit speeds for continuous network traffic. The redundant platinum power supply maintains delivery during extended operation. Eight DDR5 RDIMM slots support up to 512 GB per 3DS module for large memory footprints. Cooling is sized for the 300 W CPU envelope under constant load.

Questions about this item

How can I verify the dual 10GbE Intel X550-AT2 ports are active after installing the AMD EPYC 9004 CPU?

Check the RJ45 link LEDs on the rear panel; each port shows activity when a 10 Gigabit link is established.

What comes in the box and what must I purchase separately for the 1U8S4E-GENOA/2T?

The barebone includes the 1U chassis, 750W 80-PLUS Platinum 1+1 PSU, 12-port NVMe/SATA/SAS passive backplane, and M.2 riser; you must buy an AMD EPYC 9004 series CPU, DDR5 RDIMM or RDIMM-3DS modules, and 2.5" NVMe or SATA drives.

Which AMD EPYC 9004 processor should I choose for this single-socket SP5 system?

Select any supported EPYC 9004 SKU up to 300W TDP such as the 9654P, 9474F, 9374F, or 9184X depending on core count and frequency needs.
