AS-4145GH-TNMR
High-Density 4U GPU Server featuring Quad AMD Instinct MI300A unified-memory compute with the AS-4145GH-TNMR
The AS-4145GH-TNMR is a 4U accelerator server engineered around 4x AMD Instinct MI300A APU modules that combine Zen 4 CPU cores with CDNA 3 GPU compute, enabling tightly coupled mixed CPU+GPU execution without NUMA overhead across discrete devices. With AMD Infinity Fabric Link connectivity between APUs, the AS-4145GH-TNMR is optimized for large model training, fine-tuning, and HPC workloads that benefit from fast peer-to-peer communication and predictable latency.
Its unified-memory design provides 512GB HBM3 on-package across the platform to sustain high bandwidth for analytics and simulation kernels, while PCIe 5.0 expansion delivers headroom for high-speed networking and additional I/O. The AS-4145GH-TNMR also prioritizes local data staging with 8x front 2.5-inch NVMe bays plus dual M.2 NVMe, aligning storage throughput with accelerator utilization and minimizing pipeline stalls in data-intensive training runs.
Why Choose the AS-4145GH-TNMR?
The AS-4145GH-TNMR delivers a strong density-to-performance ratio by integrating CPU and GPU resources per APU and scaling to 4 modules in a single air-cooled 4U node. This architecture reduces interconnect complexity, supports modular AIOM/OCP 3.0 networking per configuration, and provides enterprise-ready serviceability with redundant power and remote management for repeatable deployment across clusters.
Supermicro focuses on pragmatic platform engineering for modern data centres, pairing validated chassis thermals, hot-swap power design, and IPMI/BMC operational control with security features such as TPM 2.0 and Silicon Root of Trust capabilities. The AS-4145GH-TNMR fits standardized rack integration and supports scalable GPU compute fabrics via PCIe Gen5 I/O and configurable networking.
Key Applications:
- Large language model training and fine-tuning
- HPC simulation and mixed CPU+GPU compute
- Unified-memory data analytics acceleration
- Research and CSP accelerator clusters
At Happyware - Server Hardware you benefit from non-binding offers tailored to your AS-4145GH-TNMR rollout and an extended warranty of up to 6 years to protect long-lived AI and HPC investments.
