Supermicro SYS-420GP-TNR 4U barebone server

Built for AI and HPC clusters

The Supermicro SYS-420GP-TNR is a 4U rackmount barebone server designed for AI, machine learning and high-performance computing workloads. It supports dual 3rd Gen Intel Xeon Scalable processors in LGA 4189 sockets with up to 270W TDP each using air cooling. The Intel C621A chipset provides 32 DDR4 3200 ECC memory slots for up to 8TB DRAM or 12TB with persistent memory.

Suits GPU-heavy training and rendering farms

This platform fits teams building dense GPU clusters for deep learning training, rendering or virtual desktop infrastructure. Twelve full-height PCIe 4.0 x16 slots accommodate multiple accelerators. Buyers needing integrated CPUs, memory or storage should look elsewhere because the chassis ships empty. Organisations requiring liquid-cooling support or single-socket economy will not match the thermal design or socket count.

Twelve double-width GPU slots change density

The 12 PCIe 4.0 x16 FHFL slots let you install multiple double-width accelerators without risers. Twenty-four 2.5-inch hot-swap bays accept NVMe, SATA or SAS drives for high-throughput local storage. Two M.2 sockets support either NVMe or SATA3 boot devices. A single VGA port and one Gigabit LAN from an Intel I350 controller handle basic management.
