High-Performance 5U GPU Rack Server featuring NVLink-Scale Compute Density with the 7DJ51000NA
The 7DJ51000NA is a Lenovo ThinkSystem SR780a V3 5U platform engineered for GPU-dense AI and HPC deployments where node-level bandwidth and serviceability determine cluster efficiency. Built on a dual-socket Intel Xeon Scalable 5th Gen (Emerald Rapids, LGA4677) foundation, it aligns CPU resources, I/O topology, and accelerator interconnects to sustain high utilization across multi-GPU pipelines.
With 32 DDR5 RDIMM ECC slots supporting up to 4TB, the 7DJ51000NA provides the memory capacity and reliability needed for large models, high-resolution simulation, and data-intensive preprocessing. PCIe Gen5 expansion underpins the architecture with multiple x16 lanes for accelerator and fabric integration, complemented by an NVIDIA HGX H200 8-GPU baseboard with NVLink to reduce inter-GPU latency and minimize host bottlenecks. Storage is optimized for parallel I/O using 12 hot-swap 2.5in U.2/U.3 NVMe bays plus dual M.2 2280 NVMe for OS or local staging, keeping datasets close to compute while maintaining field-replaceable design.
Why Choose the 7DJ51000NA?
The 7DJ51000NA delivers a high density-to-performance ratio by combining an 8-GPU NVLink domain with Gen5 I/O and enterprise-grade redundancy, enabling predictable scaling from single-node training to multi-node GPU clusters. Its slot-rich expansion and optional OCP NIC 3.0 support simplify integration into modern fabric designs, while dedicated BMC management and redundant 2600W PSU capacity support resilient, lights-out operations.
Lenovo designs the 7DJ51000NA with a systems engineering approach focused on validated thermals, serviceability, and long-life data centre alignment, ensuring stable operation under sustained accelerator loads and standardized rack-scale deployment practices.
Key Applications:
- AI model training on NVLink-connected GPUs
- High-throughput AI inference services
- GPU-accelerated HPC simulation
- Parallel data analytics and ETL acceleration
