Supermicro SYS-120C-TN10R 1U barebone server, 10×2.5″ bays

1U dual-socket barebone for storage-heavy workloads

The Supermicro SYS-120C-TN10R is a 1U rackmount barebone that accepts up to two Intel Xeon processors in LGA 4189 sockets. Sixteen DDR4 DIMM slots support ECC memory up to 6 TB when combined with persistent modules. Ten front 2.5-inch hot-swap bays accept NVMe, SATA and SAS drives. Two PCI-E 4.0 x16 full-height half-length slots and two M.2 2280 M-key slots provide expansion. The ASPEED AST2600 BMC handles remote management.

Tool-less drive carriers and standard rail mounting

Drive carriers slide into the front bays without screws and lock with a lever. Processors and memory install from the top after removing the air shrouds. The two PCI-E slots use standard retention brackets. Common issues include forgetting to populate both CPU sockets for full PCI-E lane count, mixing DRAM and persistent memory without following the 8+8 configuration, and exceeding the M.2 length limit of 2280. The dedicated IPMI LAN port must be cabled separately for out-of-band access.

PCI-E 4.0 and SATA 600 set the throughput ceiling

Each PCI-E 4.0 x16 slot delivers up to 32 GT/s per direction, limiting GPU or accelerator bandwidth to that generation. The ten SATA ports run at 600 MB/s, so SATA SSDs cannot exceed that rate. NVMe drives in the front bays share the CPU-attached PCI-E lanes; total NVMe bandwidth depends on the processor model installed. M.2 slots operate at PCI-E 3.0 x2, capping each at roughly 2 GB/s. The ASPEED AST2600 provides only basic 2D video output.
