1U Rackmount Barebone Server

This 1U rackmount barebone server is built for general-purpose workloads in a standard rack environment. It arrives without a CPU or memory installed, so integrators choose their own 3rd Gen Intel Xeon Scalable processor and DDR4 3200 modules. The chassis fits a single processor and provides front-access drive bays for quick maintenance.

LGA 4189 Socket and Intel C621A Chipset

The board uses the LGA 4189 socket paired with the Intel C621A chipset, accepting one 3rd Gen Intel Xeon Scalable processor. This socket and chipset combination is the single specification that determines processor compatibility; no other CPU generation will fit. Builders must source a matching Xeon processor to complete the system.

Memory and Storage Headroom

Eight DIMM slots support DDR4 3200 in a 1DPC configuration, giving ample memory capacity for virtualisation or database tasks. Storage options include three fixed 2.5-inch SATA bays and four hot-swap 3.5-inch SATA bays, allowing a mix of boot and high-capacity drives. Expansion is limited to one full-height PCIe 4.0 x16 slot, so additional controllers or accelerators cannot be added beyond that single card.

Questions about this item

What does the single PCIe 4.0 x16 slot allow me to install?

One full-height, half-length expansion card such as a GPU, NIC or RAID controller running at PCIe 4.0 speeds.

How does the Intel X710-AT2 controller limit network throughput?

It provides two 10 Gigabit Ethernet ports over copper, capping each link at 10 Gbps.

Which drive sizes fit the fixed and hot-swap bays?

Three fixed 2.5" SATA drives and four hot-swap 3.5" SATA drives can be installed simultaneously.
