About the Supermicro SuperServer SYS-420GP-TNR (A100 PCIe 80GB) — 4x NVIDIA A100 PCIe 80GB
Delivering 19.5 TFLOPS at FP32, 156 TFLOPS at TF32 (312 TFLOPS with sparsity), and exceptional INT8/FP8 throughput, the Supermicro SuperServer SYS-421GP-TNR combines four NVIDIA A100 PCIe 80GB GPUs in a single 4U rackmount chassis to accelerate demanding AI, machine learning, and high-performance computing workloads. Built on NVIDIA's proven Ampere architecture, each GPU delivers 80GB of HBM2e memory with 1,935 GB/s bandwidth, enabling rapid data movement critical for training large models and inference at scale. This configuration supports Multi-Instance GPU (MIG) technology, allowing up to 7 isolated instances per GPU for workload consolidation and resource optimization.
The Supermicro chassis pairs GPU acceleration with dual 3rd Gen Intel Xeon Scalable Processors (LGA4189) and up to 32 DDR4 ECC RDIMM/LRDIMM slots, ensuring CPU-GPU balance for complex numerical workloads. Twelve 3.5-inch hot-swap SAS/SATA drive bays provide flexible storage, while NVMe expansion via PCIe extends capacity for checkpoint files and model repositories. Redundant 2200W Titanium-level power supplies guarantee continuous operation in production environments, backed by Supermicro's IPMI 2.0 management with dedicated LAN connectivity. GPU interconnect via PCIe Gen4 x16 lanes delivers predictable bandwidth for multi-GPU communication. For AI infrastructure teams and procurement specialists evaluating enterprise-grade GPU compute, the SYS-421GP-TNR (part number SYS-421GP-TNR) represents a validated, turnkey platform.

Frequently Asked Questions about Supermicro SuperServer SYS-420GP-TNR (A100 PCIe 80GB) — 4x NVIDIA A100 PCIe 80GB
What server platforms accept the Supermicro SuperServer SYS-420GP-TNR (A100 PCIe 80GB) — 4x NVIDIA A100 PCIe 80GB?
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.
How long is the lead time on AI GPUs?
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.
Do you supply matched networking (Quantum InfiniBand / Spectrum-X)?
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.
Can you help with NVIDIA AI Enterprise licensing?
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.
