2U single-socket Genoa storage server

The B8056T70AE26HR-2T is a 2U barebone chassis built around a single AMD EPYC 9004 series processor in an SP5 socket. It targets storage workloads that demand high drive density and fast memory bandwidth in a compact rack form factor.

Suits high-IOPS NVMe deployments

Twenty-six hot-swap U.2 trays and two M.2 slots give all-flash arrays direct PCIe 5.0 attachment without SAS or SATA bottlenecks. Builders who need multi-socket scaling, GPU compute density, or legacy 3.5-inch drive support should evaluate alternative platforms.

1+1 redundant 1600W 80+ Platinum CRPS

Dual hot-swap power modules share the load and maintain uptime if one unit fails, a requirement for always-on storage clusters. The 360W CPU thermal ceiling and 24 DDR5-4800 DIMM slots complete the power-and-memory envelope.

Questions about this item

Which AMD EPYC 9004 series processor must I install in the single SP5 socket before this barebone will POST?

Any supported AMD EPYC 9004, 97x4 or 9004 with 3D V-Cache processor up to 360W TDP fits the single SP5 socket and is required for the system to operate.

Can I keep my existing DDR5-4800 RDIMM or 3DS RDIMM modules and populate all 24 slots on this motherboard?

Yes, the 24 DDR5 slots accept RDIMM and 3DS RDIMM modules at DDR5-4800 up to a total of 3,072GB, subject to the AMD memory controller limits.

After installing the CPU and memory, how do I verify the 26 NVMe U.2 bays and two M.2 slots are detected and healthy?

Use the AST2600 BMC web interface or Redfish API over the dedicated IPMI port to view drive presence, temperature and SMART status for all 26 U.2 trays and both M.2 slots.
