ASRock Rack 2U12L8E-GENOA2 2U barebone server 12+12 DIMM 8 NVMe 4 SATA 2 fixed NVMe 2000W

Dual-socket AMD EPYC barebone

The ASRock Rack 2U12L8E-GENOA2 is a 2U rackmount barebone server designed for dual AMD EPYC 9004 and 9005 series processors using the SP5 socket. It provides 12 plus 12 DIMM slots for DDR5 RDIMM and RDIMM-3DS memory in a one-DIMM-per-channel layout. This platform targets compute-dense workloads requiring high core counts and large memory capacity within a standard rack footprint.

Redundant 2000W platinum power and drive mix

The chassis includes a 1+1 CRPS redundant power supply rated at 2000W with 80-PLUS Platinum efficiency. Storage flexibility comes from eight hot-swap bays accepting 3.5-inch or 2.5-inch NVMe PCIe 4.0 x4 or SATA drives, four hot-swap 3.5-inch or 2.5-inch SATA bays, and two fixed 2.5-inch NVMe PCIe 5.0 x4 bays. This mix lets operators balance capacity, speed and cost without external enclosures.

Expansion slots and fixed NVMe placement

Two full-height half-length PCIe 5.0 x16 slots or one x16 plus two x8 slots provide room for accelerators, networking or storage controllers. The two fixed NVMe bays sit inside the chassis, meaning those drives are not hot-swappable and require downtime for replacement. Builders needing full hot-swap serviceability for every NVMe device should note this constraint before deployment.
