Silver 1U rackmount chassis with twelve 3.5 inch and four 2.5 inch drive bays

ASRock Rack

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

SKU CH-S420-29CZY MPN 1U12L4E-GENOA/2Q

1U rackmount barebone with twelve 3.5″ SATA bays, four 2.5″ NVMe bays and dual 25GbE SFP28 networking

  • 12 hot-swap 3.5" SATA bays for high-capacity storage
  • 4 hot-swap 2.5" NVMe bays with PCIe 4.0 x4 speed
  • Dual SFP28 25GbE ports for fast networking
  • 1U rackmount with 1+1 1000W redundant power supply
  • Single SP5 socket supports AMD EPYC 9004/9005 processors

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.

Questions about this item

How many 3.5" SATA drives can the 1U chassis hold before internal space runs out?

The 1U chassis provides twelve hot-swap 3.5" SATA bays, which is the physical limit for that form factor.

What is the power capacity of the redundant supply when the server runs continuously?

A 1+1 1000W redundant power supply feeds the system, so sustained load is capped at 1000W.

Which processor socket must be populated for the barebone to operate?

A single SP5 (LGA 6096) socket for AMD EPYC 9004 or 9005 series CPUs is required.
