Dual-Socket Xeon 6900 Platform

The Supermicro SYS-222HA-TN is a 2U rack server designed for dual Intel Xeon 6900 series processors with P-cores, supporting up to 128 cores and 256 threads per CPU. It targets organisations building high-density compute clusters for AI training, HPC workloads, or large-scale virtualisation where maximum core count and memory bandwidth are primary requirements.

PCIe 5.0 Expansion and Storage Flexibility

Four PCIe 5.0 x16 slots accept up to four double-width GPU or accelerator cards with CPU-to-GPU interconnect, while two AIOM slots add OCP NIC 3.0 networking. Eight hot-swap 2.5-inch bays handle NVMe, SAS, or SATA drives with RAID 0/1/5/10 support, and two internal M.2 NVMe slots provide boot or cache capacity without consuming front bays.

DDR5 Memory Constraints

Twenty-four DDR5 slots deliver up to 6 TB at 6400 MT/s with RDIMMs or 6 TB at 8800 MT/s with MRDIMMs in a 1 DPC configuration; mixing RDIMM and MRDIMM types is not supported. The platform requires Xeon 6900 series CPUs in Socket BR (LGA-7529) and does not accommodate earlier Xeon generations or non-P-core variants.

Questions about this item

Will the hot-swap drive backplane or the M.2 slots need replacement during the server's lifespan?

The backplane supports 2.5-inch NVMe, SAS and SATA drives and two internal M.2 NVMe slots; both are passive and do not have a scheduled replacement interval.

What is the first limit reached when both Intel Xeon 6900 series processors run at their 500 W TDP continuously?

The cooling solution must dissipate up to 500 W per CPU, so thermal capacity of the chosen air or liquid cooler becomes the limiting factor.

How loud are the fans and how much power does the 2U chassis draw when fully populated with GPUs and storage all day?

Four double-width GPUs, up to 24 DDR5 DIMMs and 8 hot-swap drives plus dual 500 W CPUs push power draw toward the supply rating; fan speed ramps with inlet temperature to keep components within spec.
