Artificial intelligence (AI) and cloud software corporations Okestro said on the 28th that it signed a memorandum of understanding (MOU) with AI data center development and operations corporation DCK to build a "sovereign AI cloud data center."
Under the agreement, the two sides will use Okestro's new headquarters site in Yeouido to build an urban Edge AI data center and implement it as a customer-dedicated "sovereign AI cloud data center."
The "sovereign AI cloud data center" to be built in Yeouido will have a capacity of 5 megawatts (MW) and will be designed to connect large-scale AI workloads based on graphics processing units (GPUs), Korea-made AI Semiconductor (NPU), and Korea-made large language models (LLMs). The goal is to implement a secure, private "sovereign AI" environment in which customers can directly set and manage data and operational policies through a customer-dedicated environment that does not rely on external clouds or shared resources.
It also plans to implement a large-scale AI-dedicated infrastructure required for high-performance GPU operations by applying high-density power and cooling designs that can accommodate up to 30 kilowatts (kW) per rack and liquid-cooling facilities. The company said it is designed with a rear door heat exchanger (RDHx) method that removes the exhaust heat of air-cooled equipment with liquid cooling, enabling effective thermal control even in high-density GPU environments.
Okestro will introduce its AI and cloud full-stack solutions to the data center to provide everything from AI services to cloud infrastructure and integrated operations management under a single architecture. This will allow customers to operate a reliable and predictable private AI infrastructure based on integrated software, hardware, and colocation space services without building their own data centers or deploying separate operations personnel.
DCK will be responsible for the design and construction of the data center. The two sides will cooperate across the entire data center build process, from development and permitting to EPC (engineering, procurement, and construction), operations, and sales. DCK has pursued the development of AI-specialized data centers at major hubs nationwide and possesses data center design and construction capabilities, including recently securing permits for urban Edge AI data centers in the greater Seoul area.
Okestro plans to gradually expand the construction of sovereign AI data centers based on this agreement. Starting this year, it will apply its AI and cloud full-stack solutions to DCK's Magok and Cheongdam AI data centers to meet AI infrastructure demand by industry.
Okestro Chief Executive Kim Beom-jae said, "Building a 'sovereign AI cloud data center' at the new Yeouido headquarters is an important step in concretizing Okestro's AI infrastructure strategy," and added, "We will gradually expand private AI data centers as key hubs that can stably operate high-performance GPUs through high-density power and cooling designs, and we will begin in earnest to build a sovereign AI environment."
