2U dual-socket barebone for scale-out workloads

The Supermicro SYS-620U-TNR is a 2U rackmount barebone designed for dual 3rd Gen Intel Xeon Scalable processors in LGA 4189 sockets. It targets virtualization, HPC, cloud computing and software-defined storage deployments where dense compute and storage share a single chassis. No CPUs or memory are installed, so integrators choose exact SKUs per workload.

32 DDR4 slots and twelve hot-swap bays

The board provides 32 288-pin DDR4 3200 slots supporting up to 12 TB of ECC memory across both processors. Twelve 3.5" hot-swap bays accept NVMe, SATA or SAS drives without cabling each device. Seven PCIe 4.0 slots — four full-height 10.5" and three low-profile — leave room for GPU, networking or storage controllers while the redundant 1200 W Titanium supplies free rack PDU budget.

Redundant Titanium supplies

Dual 1200 W Titanium-level power supplies deliver efficiency and N+1 redundancy without extra cabling. Front-access hot-swap bays let technicians replace drives without sliding the chassis out of the rack. A single COM port, VGA output and two rear USB 3.0 ports cover basic KVM and media needs for headless operation.

Questions about this item

What limits sustained performance first, the 1200 W redundant Titanium power supplies or the 12 hot-swap drive bays?

The 1200 W redundant Titanium power supplies set the sustained power ceiling for the entire chassis.

How loud or hot does the system get when the 1200 W redundant Titanium supplies run continuously?

Redundant Titanium supplies operate at high efficiency, reducing waste heat and fan speed during all-day operation.

Which CPUs and memory must I already own to populate the dual LGA 4189 sockets and 32 DDR4 3200 slots?

Two 3rd Gen Intel Xeon Scalable processors and up to 12 TB of DDR4 3200 ECC RDIMMs are required.
