The Supermicro SYS-621GU-TNXR is a 2U rackmount GPU server engineered to support up to eight double-width GPU accelerators, making it one of the most compute-dense platforms in its form factor. Built on the X13 generation architecture with dual 4th Gen Intel Xeon Scalable processor support, the system delivers the PCIe 5.0 bandwidth and memory capacity necessary to feed modern large-scale AI training and high-performance computing workloads. The chassis accommodates GPU interconnects at full bandwidth while maintaining the thermal and power delivery infrastructure required for sustained operation under continuous workloads in production datacenter environments.
The SYS-621GU-TNXR supports dual Intel Xeon Scalable processors (4th Gen, Sapphire Rapids) with up to 32 DIMM slots accommodating DDR5 registered memory, providing the high-bandwidth CPU-to-GPU data paths essential for deep learning model training, inference serving, and scientific simulation. Eight PCIe 5.0 x16 GPU slots enable full-bandwidth connectivity for each accelerator, while the platform also integrates high-speed networking options and multiple NVMe storage bays to eliminate I/O bottlenecks across demanding pipeline stages. Supermicro's Building Block Solutions architecture allows the system to be configured with a range of GPU types including NVIDIA H100, A100, and other SXM or PCIe accelerators depending on the specific configuration selected.
Designed for enterprise datacenters, cloud service providers, and AI infrastructure deployments across regions including the UAE, GCC, EMEA, and APAC, the SYS-621GU-TNXR is available through Omnixon Global. The platform aligns with Supermicro's green computing initiatives, incorporating high-efficiency redundant power supply units and intelligent fan management to optimize power usage effectiveness at the rack level. Its 2U density makes it particularly well-suited for operators seeking to maximize GPU compute per rack unit while retaining full compatibility with standard 19-inch datacenter cabinet infrastructure.

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.
Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.
Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.
Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
