1U barebone for Xeon Scalable servers

This 1U rackmount barebone accepts a single 3rd Gen Intel Xeon Scalable processor in an LGA 4189 socket. Eight DDR4 DIMM slots support RDIMM, LRDIMM, 3DS and Intel Optane Persistent Memory 200 series modules. It targets general-purpose workloads such as database processing and storage in data-centre or SMB environments.

Redundant Platinum 750 W power with front airflow

A 1+1 Platinum 750 W slim PSU pair provides redundancy while drawing cool air through the front hot-swap bays. The Aspeed AST2500 BMC with 16 MB video memory handles IPMI over a dedicated RJ45 port, keeping management traffic separate from the dual 10 GbE Intel X710-AT2 links.

Mixed NVMe and SATA bays plus PCIe 4.0 x16

Four 2.5-inch bays accept NVMe PCIe 3.0 x4 or SATA drives, while four 3.5-inch bays take SATA drives, all hot-swappable. A full-height half-length PCIe 4.0 x16 slot is available via the RB1UX16_G4 riser, and an M.2 slot supports PCIe 3.0 x4 or SATA 6 Gb/s. Builders needing more than one CPU socket or more than eight memory channels should look elsewhere.

Questions about this item

How do I install the CPU and what step is often missed?

Install a 3rd Gen Intel Xeon Scalable processor into the LGA 4189 socket; the step often missed is applying thermal paste and securing the heatsink before powering on.

What maintenance or replacement will the power supply need later?

The 1+1 Platinum 750W Slim PSU modules are hot-swap; a failed unit can be replaced without shutting down the server.

What limit appears first under sustained heavy storage workloads?

The four 2.5" NVMe bays run at PCIe3.0 x4 each, so aggregate NVMe bandwidth caps before the single PCIe4.0 x16 slot or 10 Gigabit LAN.
