Supermicro 221H-TN24R-G1-OTO-12 rack server, Xeon Gold 6548Y+, 512GB DDR5, 15.2TB SSD

2U rack server with 24 bays

The Supermicro 221H-TN24R-G1-OTO-12 is a 2U rack server system built around an Intel Xeon Gold 6548Y+ processor. It ships with 512GB of DDR5 memory and 15.2TB of solid-state storage. The platform suits data-intensive workloads such as virtualisation, database hosting and high-performance computing clusters.

24 drive bays limit internal expansion

The chassis provides twelve front-accessible bays and twelve rear bays, totalling twenty-four drive slots. Once these bays are populated, no further internal storage can be added without external enclosures. The DDR5 memory fills the available DIMM sockets, so capacity cannot be increased beyond the supplied 512GB.

Replaces older 2U systems with fewer cores

This server replaces earlier 2U platforms that offered lower core counts and slower memory bandwidth. The jump is worth it when workloads demand the 6548Y+ processor's core density and DDR5 throughput for parallel tasks. It is not for buyers who need GPU acceleration, additional PCIe slots beyond the barebones layout, or higher single-thread clock speeds.
