Samsung SDS Dongtan Data Center: Technical Specs
Status: Operational (Primary HPC Cloud Hub) | Location: 14 Dongtan-daero 9na-gil, Hwaseong-si, Gyeonggi-do 18488, South Korea
Project Overview
The Samsung SDS Dongtan Data Center is a specialized high-performance computing facility in South Korea, developed to support computationally intensive workloads such as advanced artificial intelligence model training, large-scale big data analytics, scientific computing, and high-density enterprise research and development applications. Recognized as South Korea’s first data center dedicated exclusively to High-Performance Computing (HPC), the facility represents a significant step in the evolution of enterprise infrastructure toward specialized computing environments capable of handling workloads that demand substantially greater processing capacity than conventional data centers. The facility operates as part of the Samsung Cloud Platform (SCP), providing scalable computing resources and cloud-based infrastructure for organizations requiring advanced processing capabilities. Its architecture is optimized for intensive workloads involving large datasets, complex simulations, AI development, and other accelerated computing applications. A major strength of the Dongtan facility is its integration into a tri-data-center mutual active backup architecture involving Samsung SDS’s Suwon and Sangam data centers. This configuration is designed to enhance service continuity and resilience by distributing critical infrastructure and workloads across multiple locations, reducing dependence on a single facility and strengthening disaster recovery capabilities. The approach enables Samsung SDS to provide reliable computing and cloud services for mission-critical enterprise applications while maintaining operational flexibility. By combining dedicated HPC infrastructure, cloud-based computing capabilities, advanced AI workload support, and geographically distributed redundancy, the Samsung SDS Dongtan Data Center demonstrates the growing importance of purpose-built HPC facilities within modern digital infrastructure. The facility also provides a foundation for supporting increasingly sophisticated AI and data-intensive workloads as enterprises accelerate adoption of advanced computing technologies.
