Configuration overview: Supermicro SYS-421GE-TNHR2-LCC server with 8x NVIDIA H100 GPUs
The Supermicro SYS-421GE-TNHR2-LCC server is a 4U liquid-cooled platform built around an NVIDIA HGX H100 SXM 8-GPU baseboard. This type of system is typically deployed in enterprise AI clusters where power, cooling, GPU interconnect, and networking determine real performance.
It is commonly used for:
Multi-node training (distributed training with high-speed fabric)
Large-scale inference (high concurrency and batching)
Shared GPU infrastructure (virtualized or multi-tenant environments)
HPC + AI pipelines (depending on software stack)
Full configuration: Supermicro SYS-421GE-TNHR2-LCC server with 8x NVIDIA H100 GPUs
Base system: Supermicro SYS-421GE-TNHR2-LCC 4U liquid-cooled server
Component | Details | Why it matters |
Server | Supermicro SYS-421GE-TNHR2-LCC | Integrated HGX platform (power, cooling, firmware alignment) |
Form factor | 4U, liquid-cooled (LCC) | Supports sustained GPU power in dense deployments |
Condition | Brand new in crates | Clear baseline for acceptance testing |
Commercial term | FOB (Free On-Board) Supermicro | Defines shipping handover point |
GPUs: 8x NVIDIA H100 80GB SXM (HGX 8-GPU)
Component | Details | Why it matters |
GPUs | 8x NVIDIA H100 80GB SXM | High GPU memory capacity per node |
GPU memory | 80GB HBM2e per GPU | Helps fit larger models and higher batch sizes |
Interconnect | NVLink + NVSwitch (HGX) | High GPU-to-GPU bandwidth for multi-GPU training |
Practical note:
For multi-GPU training, NVSwitch topology is often the difference between “8 GPUs installed” and “8 GPUs scaling well.”
CPUs: 2x Intel Xeon Platinum 8558P
Component | Details | Why it matters |
CPUs | 2x Intel Xeon Platinum 8558P | Host CPU capacity and PCIe for GPUs, storage, and NICs |
CPU generation | 5th Gen Intel Xeon Scalable (Emerald Rapids) | Current platform generation for this class of server |
Memory: 1TB DDR5 (16x 64GB)
Component | Details | Why it matters |
Memory | 1TB DDR5 (16x 64GB) | Headroom for preprocessing, dataloading, and multi-service nodes |
Scalability note (platform capability):
The platform supports higher memory capacities depending on DIMM selection and speed targets. This matters for CPU-heavy pipelines and multi-tenant deployments.
Storage: 2x 960GB NVMe (OS) + chassis expandability
Component | Details | Why it matters |
OS storage | 2x 960GB NVMe | Fast boot, image pulls, and local cache |
Front bays | 8x hot-swap 2.5" NVMe U.2 bays (chassis support) | Optional local high-speed dataset / scratch |
M.2 | 2x M.2 NVMe slots (platform support) | Common for mirrored boot or hypervisor OS |
Configuration clarity:
This offer includes 2x 960GB NVMe installed. Remaining bays can be left empty or populated depending on project needs.
Networking: On-Board 10GbE + PCIe expansion for cluster fabric
Component | Details | Why it matters |
On-Board LAN | 2x 10GbE RJ45 (Intel X710-AT2) | Reliable management and baseline connectivity |
Expansion | PCIe 5.0 slots available for fabric NICs | Enables InfiniBand or 100/200/400GbE for training |
Power: High-capacity redundant PSUs (deployment-critical)
Component | Details | Why it matters |
Power supplies | 4x 5250W (2+2 redundant), Titanium efficiency | Required for 8x GPU power draw and stable operation |
Cooling: liquid cooling requirements (what IT needs to know)
This is a liquid-cooled system designed for data center environments with appropriate infrastructure.
Typical LCC elements include:
Direct-to-chip (D2C) cold plates for major heat sources
Supporting fans for non-liquid-cooled components
Facility requirements for coolant loop integration and service procedures
Platform overview: Supermicro SYS-421GE-TNHR2-LCC server with 8x NVIDIA H100 GPUs
The Supermicro SYS-421GE-TNHR2-LCC server with 8x NVIDIA H100 SXM is built for teams that want:
Standard rack deployment and cluster scaling
Control of OS image, drivers, and monitoring
Predictable data handling and enterprise operations
Real performance depends on:
GPU topology (NVSwitch)
Cluster fabric (NIC choice + fabric tuning)
Software stack (driver versions, NCCL settings, container runtime, scheduler)
To keep this readable, those items should be validated during acceptance testing rather than described as guarantees.
