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.

Questions about this item

How does the 24-bay chassis affect which 15.2 TB SSD configuration I should pick?

The 24-bay front panel is designed for 2.5-inch drives, so the 15.2 TB SSD capacity will occupy a portion of those bays depending on the individual drive sizes used.

What does the 512 GB DDR5 figure mean for actual workload performance in this 2U server?

512 GB of DDR5 memory feeds the Xeon Gold 6548Y+ with high bandwidth and low latency, supporting large in-memory databases, virtualization clusters and multi-threaded compute tasks.

Which interface standard connects the 15.2 TB SSD to the Xeon Gold 6548Y+ and what throughput limit does it impose?

The SSDs connect through the platform's native PCIe lanes directly to the Xeon Gold 6548Y+, so throughput scales with the CPU's lane count and the drive's own PCIe generation.
