ASRock Rack 1U12L4E-GENOA/2Q barebone server 12×3.5″ SATA 4×2.5″ NVMe dual SFP28 25GbE

1U dual-socket barebone for dense storage

The ASRock Rack 1U12L4E-GENOA/2Q is a 1U rackmount barebone designed for storage-heavy workloads. It targets system integrators and data-centre operators who need high drive density in a single rack unit. The platform accepts a single AMD EPYC 9004 or 9005 series processor in the SP5 socket. It ships with a redundant 1000 W power supply for continuous operation.

Twelve SATA bays plus four NVMe slots

Twelve hot-swap 3.5-inch SATA bays provide the bulk capacity layer, while four hot-swap 2.5-inch bays accept PCIe 4.0 x4 NVMe drives for faster tiers. Two M-key sockets add flexibility for additional PCIe 5.0 x4 or SATA 6 Gb/s devices. Dual SFP28 25 GbE ports handle network traffic directly on the board. An OCP 3.0 slot and two PCIe 5.0 x16 slots leave room for specialised accelerators or extra networking.

Memory and CPU headroom for scale-out

Twelve DDR5 DIMM slots in a 1 DPC layout support RDIMM and 3DS modules, giving ample memory bandwidth for multi-threaded storage services. The single-socket design limits maximum core count to one EPYC 9004 or 9005 CPU, so workloads needing dual-socket scale must look elsewhere. Builders requiring more than sixteen drive bays or GPU-class PCIe slots will need a larger chassis.
