AI training and high-performance compute workloads demand the NVIDIA Hopper architecture, and the Supermicro SuperServer SYS-4U-H100PCIe delivers exactly that foundation. This 4U rackmount system accommodates up to 4x NVIDIA H100 PCIe 80GB GPUs, each featuring 80GB of HBM2e memory and 700 GB/s memory bandwidth, all connected via PCIe Gen 5 for maximum data throughput. Built around dual 4th Gen Intel Xeon Scalable Processors (Socket LGA-4677), the platform pairs GPU acceleration with enterprise-grade CPU compute, while 16x DDR5 Registered ECC DIMM slots ensure system stability under sustained workloads.
For IT infrastructure teams and AI infrastructure specialists, this Supermicro system (part number SYS-421GT-HNR) balances density, performance, and manageability. The redundant hot-swap 80 PLUS Titanium power supplies and high-airflow redundant fan design maintain thermal performance even under full GPU TDP operation. Connectivity includes dual 10GBase-T onboard LAN (Intel), NVMe M.2 support, and 4x 3.5-inch hot-swap SATA/SAS drive bays for flexible storage configurations. Enterprise management features—IPMI 2.0, Redfish API, and dedicated BMC management—enable seamless integration into existing data center orchestration frameworks. Support for Windows Server, Red Hat Enterprise Linux, Ubuntu, and VMware ESXi ensures broad compatibility across common enterprise environments.

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.
