Supermicro SYS-221H-TN24R-G1 rack server dual Xeon 6548Y+ 32C 2.5GHz 256GB DDR5 3.8TB+480GB NVMe

Dual-socket Xeon server with E1.S bays

The Supermicro SYS-221H-TN24R-G1 is a 2U rack server built around two Intel Xeon 6548Y+ processors. Each CPU provides 32 cores at 2.5 GHz with 60 MB of cache. The system ships with 256 GB of DDR5-5600 memory across 32 slots and supports up to 8 TB total. Storage includes one 3.8 TB E1.S NVMe SSD and one 480 GB M.2 NVMe SSD.

Suits dense compute and fast local storage

This server fits workloads that need high core counts and front-access NVMe density in a 2U form factor. The 24 E1.S hot-swap bays allow large all-flash arrays without occupying PCIe slots. Buyers who need GPU acceleration, additional PCIe expansion beyond the provided networking, or 3.5-inch drive support should look at a different platform.

24 front E1.S NVMe hot-swap bays

The chassis provides 24 front-access E1.S drive bays wired for NVMe, plus two internal M.2 slots that accept NVMe or SATA modules. This bay count and form factor determine how much high-speed flash can be installed directly in the server. Networking is handled by a single dual-port 25 GbE SFP28 controller and power comes from two 2000 W titanium-level supplies.
