Technical Architecture


Dual-CPU AMD EPYC Platform

The system is based on an AMD EPYC server platform designed to provide processing resources for data-intensive applications and accelerator-driven computing. CPU selection and supported configurations should be confirmed against the manufacturer's specifications.

GPU-Accelerated AI Computing

Designed for GPU-intensive workloads, the platform can be configured around compatible accelerators to support AI model development, deep learning, scientific computing, and parallel-processing applications. GPU models, quantities, power requirements, and software compatibility depend on the validated system configuration.

4U Rackmount Design

The 4U chassis integrates compute and accelerator resources into a rackmount form factor for data center and enterprise infrastructure. Deployment planning should consider rack space, power distribution, thermal requirements, airflow, and service access.

Memory, Storage and Networking

Configure supported memory and storage options to suit dataset sizes, model checkpoints, application requirements, and performance targets. Network adapters and interconnects should be selected according to the workload, bandwidth requirements, and compatibility with the final configuration.
