About the Supermicro SuperServer SYS-420GP-TNR — 4x NVIDIA A100 SXM4 80GB System
The Supermicro SuperServer SYS-420GP-TNR delivers 320GB of HBM2e memory with up to 600 GB/s bidirectional bandwidth per GPU across its 4x NVIDIA A100 SXM4 80GB accelerators. Built on NVIDIA's Ampere architecture, this 4U rackmount system combines four discrete GPU modules—each with 80GB HBM2e and 312 TFLOPS of FP16 tensor performance with sparsity—connected via third-generation NVIDIA NVLink for seamless multi-GPU workloads. The Supermicro SYS-420GP-TNR pairs these accelerators with dual 3rd Generation Intel Xeon Scalable Processors (LGA 4189, Ice Lake-SP), 32 DIMM slots supporting up to 6TB DDR4 ECC Registered memory, and PCIe 4.0 expansion. Storage flexibility includes 8x 2.5" hot-swap drive bays for NVMe, SATA, or SAS media, while redundant 3000W Titanium-level power supplies ensure enterprise-grade reliability.
AI infrastructure teams, machine learning operations groups, and data scientists select this platform for compute-intensive training, inference, and simulation workloads that demand massive parallel processing and ultra-low inter-GPU latency. The combination of 320GB total GPU memory and NVLink 3 bandwidth makes it ideal for large language models, computer vision pipelines, and numerical simulations where data movement between accelerators is a critical bottleneck. Supermicro's IPMI 2.0 management with dedicated control port and DCMS compatibility streamline deployment and monitoring in hyperscale environments. Native support for Linux (Ubuntu, RHEL, CentOS) and Windows Server ensures broad software ecosystem compatibility.
Organizations deploying the SYS-420GP-TNR benefit from a proven, field-tested architecture backed by Supermicro's engineering and support infrastructure.

Frequently Asked Questions about Supermicro SuperServer SYS-420GP-TNR — 4x NVIDIA A100 SXM4 80GB System
What server platforms accept the Supermicro SuperServer SYS-420GP-TNR — 4x NVIDIA A100 SXM4 80GB System?
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.
