Supermicro SYS-221H-TNR 2U barebone server 32 DIMM slots 8x 2.5" NVMe SAS SATA bays 4 PCIe 5.0 x16 slots

Dual-socket Xeon barebone for dense compute

The Supermicro SYS-221H-TNR is a 2U server barebone that accepts two 5th or 4th Gen Intel Xeon Scalable processors in LGA-4677 sockets. It provides 32 DIMM slots for DDR5-5600 RDIMMs and eight hot-swap 2.5-inch bays that take NVMe, SAS or SATA drives. Four PCIe 5.0 x16 slots and up to two AIOM slots compliant with OCP NIC 3.0 give extensive expansion for accelerators or networking.

Suits GPU-heavy workloads; not for minimal expansion

This platform suits builders who need up to four double-width or eight single-width GPU and accelerator cards in a single chassis. It also fits teams requiring dense local storage with mixed drive protocols. Buyers who only need a single processor, fewer than 16 DIMM slots, or a single PCIe 5.0 x16 slot should look at smaller configurations that match those requirements.

Needs CPUs, memory, drives and cooling to complete

A working system requires two compatible Xeon Scalable CPUs, DDR5 RDIMMs, storage drives for the 2.5-inch bays and the two internal M.2 slots, plus an operating system. The four heavy-duty hot-swap fans are included and managed by the baseboard management controller. The flexible PCIe layout frees up space for high-bandwidth add-in cards without using external enclosures.
