- Two M.2 PCIe 3.0 slots and CXL 2.0 support accelerate storage and memory expansion
Dual-socket EPYC barebone for dense storage
The Supermicro AS -2126HS-TN is a 2U barebone server built around two AMD EPYC 9004 or 9005 series processors. It targets organisations that need maximum local NVMe capacity in a compact rack footprint. The chassis delivers up to 24 front hot-swap 2.5 inch bays supporting NVMe, SAS and SATA drives. Two internal M.2 PCIe 3.0 slots add boot or cache flexibility without consuming front bays.
24 NVMe bays plus dual CPU headroom
Twenty-four front bays provide high-density flash storage for databases, caching tiers or content delivery workloads. Each processor exposes PCIe 5.0 lanes directly to the backplane, so NVMe drives run at full speed without bottlenecks. The platform supports 24 DDR5 DIMM slots in a one-DIMM-per-channel layout, giving large memory capacity for in-memory workloads. Expansion is handled through four PCIe 5.0 x16 slots and one AIOM slot, with optional configurations up to eight x8 slots.
Rack-ready platform with GPU and CXL headroom
The 2U form factor fits standard racks while leaving room for full-length accelerators in the x16 slots. CXL 2.0 support enables memory expansion or coherent accelerator attach when compatible devices arrive. A single OCP NIC 3.0 AIOM slot handles networking choices without using a PCIe slot. Builders supply both CPUs, memory, drives and add-in cards to complete the system.

Questions about this item
Will the 24 NVMe bays and PCIe 5.0 slots work with my existing PCIe 3.0 NVMe drives and add-in cards?
The 24 front 2.5" bays accept NVMe, SAS and SATA drives; PCIe 5.0 slots are backward compatible with PCIe 3.0 and 4.0 devices, so older drives and cards will function at their native speeds.
How can I verify the dual EPYC 9004/9005 CPUs and 24 DDR5 DIMM slots are recognised after assembly?
Enter the BIOS or UEFI on first boot; the main dashboard will list both EPYC processors, show all 24 DDR5 slots populated or empty, and confirm each PCIe 5.0 link width.
Which components are included in the barebones chassis and what must I source separately?
The unit ships with the 2U chassis, motherboard, 24 hot-swap 2.5" backplanes, two M.2 PCIe 3.0 slots, AIOM networking slot and PCIe 5.0 risers; you must add EPYC 9004/9005 CPUs, DDR5 memory, drives, GPU or CXL 2.0 cards and an OCP 3.0 NIC.
