1U rack server with 24-core Xeon
The Supermicro AS -121H-TNR-02-G1 is a 1U rack server built for general-purpose workloads. It ships with a single Intel Xeon Gold 6542Y processor running at 2.90 GHz with 24 cores and 60 MB of L3 cache. Memory is populated with 256 GB of DDR5 ECC RDIMM across the 32 available slots. Storage includes one 3.84 TB U.2 NVMe SSD and the system supports RAID 0, 1, 5 and 10 configurations.
Check power, network and expansion space
Verify that your rack can supply two 1200 W Titanium-level power supplies and that you have cabling for the dual 10 GbE RJ45 ports. The chassis provides one PCIe 5.0 x16 full-height half-length slot for additional cards. Cooling is handled by eight hot-swap counter-rotating fans. Security features include TPM 2.0, Silicon Root of Trust compliant with NIST 800-193, signed firmware, secure boot and automatic firmware recovery.
Suits dense compute and virtualisation hosts
This server suits teams needing high core density and large memory capacity in a single rack unit for virtualisation, database or container workloads. Buyers who require dual-socket scaling should look elsewhere because the platform supports a maximum of one processor. Organisations needing more than one NVMe drive from the factory or additional PCIe slots beyond the single x16 will need a different chassis.

Questions about this item
Does the server ship with any drive trays or caddies, or must I supply my own for the 3.84TB NVMe SSD?
The 3.84TB NVMe SSD is factory-installed in a U.2 bay; the chassis includes the necessary trays for that drive, so no separate caddy is required.
The spec lists DDR5-5600 at 1 DPC and DDR5-4400 at 2 DPC — which configuration matches the installed 256GB?
The 256GB ships as a 1 DPC population running at 5600MT/s, leaving the second DIMM slot per channel free for later expansion at 4400MT/s.
How does the single 24-core Xeon Gold 6542Y at 2.90 GHz perform when the 3.84TB NVMe drive is under sustained write load?
The 24-core processor and dual 10GbE ports keep I/O flowing, while the 1200W titanium PSUs and eight counter-rotating fans maintain thermal headroom during heavy writes.
