Supermicro Server 4U Rackmount Chassis Sys 621H Tn12R Cloud Virtualization

Product Description

The Supermicro SYS-621H-TN12R is a 2U dual-socket Hyper server built for virtualization, SDS, AI inference, and HPC. It supports 4th/5th Gen Intel Xeon Scalable processors (up to 64 cores per CPU) and 32 DDR5 DIMM slots (up to 8TB) , delivering massive compute and memory density. Unlike standard 2U servers, it features 12 x 3.5” front hot-swap NVMe/SAS/SATA bays (supports 2.5” adapters), up to 4 double-width GPUs (H100, L40S), and CXL 1.1 support for accelerator expansion. With redundant Titanium PSUs and IPMI 2.0, it balances performance, storage flexibility, and enterprise reliability.

Key Differentiators

  • Dual 4th/5th Gen Intel Xeon Scalable (up to 64 cores/CPU, 350W TDP)

  • 32 x DDR5 DIMM slots: up to 8TB at 5600 MT/s

  • 12 x 3.5” hot-swap NVMe/SAS/SATA front bays + 2 x M.2 PCIe 4.0

  • Up to 4 double-width GPUs (H100, L40S, A100)

  • 4 x PCIe 5.0 x16 + 2 x PCIe 5.0 x16 AIOM (OCP 3.0), CXL 1.1

  • Onboard SATA/NVMe RAID 0/1/5/10, Intel VROC support

  • Redundant 1200W Titanium PSUs (96% efficiency); 800W/1600W options

  • IPMI 2.0, KVM-over-LAN, TPM 2.0, SuperDoctor 5
