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.
