About the Gigabyte G481-S80 8x GPU Liquid-Cooled Server H100 SXM5 (Bare)
The Gigabyte G481-S80 is an 8x GPU liquid-cooled server built to deliver maximum accelerated compute density in a compact 4U rack form factor. This bare system features 8x NVIDIA H100 SXM5 GPUs with NVLink 4.0 connectivity via NVSwitch, delivering the bandwidth and inter-GPU communication required for large-scale distributed AI, HPC, and data analytics workloads. Powered by dual Intel Socket LGA 4677 processors (4th Gen Intel Xeon Scalable), the platform supports 32 DDR5 RDIMM / 3DS RDIMM slots (16 per CPU) and direct liquid cooling optimized for high-density datacenter GPU deployment.
The G481-S80-AAX1 combines enterprise-grade reliability with flexible expansion: 8x 2.5" hot-swap NVMe/SATA/SAS storage bays, OCP 3.0 slot for network adapters, and PCIe expansion for InfiniBand or Ethernet HCAs. Redundant Titanium-level power supplies and IPMI 2.0 management via ASPEED AST2600 BMC ensure robust remote administration and fault tolerance. Operating within the 10–35°C ambient air temperature range, the system requires facility liquid cooling loop integration for GPU thermal management. For AI infrastructure teams and storage architects evaluating massive-scale training clusters, Gigabyte's G481 Series delivers density and performance in bare configuration, allowing you to specify CPUs, memory, and storage independently.

Frequently Asked Questions about Gigabyte G481-S80 8x GPU Liquid-Cooled Server H100 SXM5 (Bare)
What server platforms accept the Gigabyte G481-S80 8x GPU Liquid-Cooled Server H100 SXM5 (Bare)?
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.
