KT Launches 13th Data Center in Yongsan

The Nation's First Single-Line 100Gbps Speed Provided
Capable of Accommodating 100,000 Servers in 8 Server Rooms

[Asia Economy Reporter Han Jinju] KT has started operating its 13th Internet Data Center (IDC) in Yongsan.

On the 5th, KT announced the opening of ‘KT DX IDC Yongsan’ (hereafter Yongsan IDC) in Yongsan-gu, Seoul. Yongsan IDC was constructed with a total floor area of 48,000㎡, spanning from 6 basement levels to 7 above-ground floors. It can operate a large-scale server capacity of over 100,000 units across 8 server rooms. The capacity of 100,000 servers is equivalent to accommodating 30,000 data items from the National Library of Korea.

Yongsan IDC is the first in Korea to provide 100Gbps speed through a single line using its own network. It can process terabit (Tbps) scale data within a single IDC, ensuring stable service. KT’s IDCs located in the metropolitan area (Yongsan, Mokdong, Gangnam, Bundang) are connected to form one massive IDC, with up to 8 diversified network paths.

Even if a sudden large volume of traffic occurs at one IDC, data is supplied without disruption by routing through adjacent IDCs to access the backbone network. Located in the heart of Seoul, Yongsan IDC is adjacent to major communication facilities such as Guro and Hyehwa, minimizing internet speed and bandwidth delays.

Through hyper-connected exchange services, Yongsan IDC is directly connected to all domestic and international cloud systems, including Amazon and Google. It also offers a ‘Hybrid Managed Service Provider (MSP)’ that supports operation and management by KT experts in IT environments mixing local devices and cloud systems.

To prepare for emergencies, it is the first domestic IDC to have a dual power substation and the first IDC in the Seoul area to have a high-capacity 154kV power reception voltage. It adopted a pillar-free server room structure and a top-grade seismic design to withstand earthquakes. Additionally, a four-step security system from the entrance to the server rooms ensures thorough security. Furthermore, it automates facilities using AI platforms and optimizes space operation through 3D modeling. It integrates operation of IDCs across various locations using IoT and big data-based automatic diagnostic systems.

Yongsan IDC has significantly improved cooling costs, which account for a large portion of data center power consumption. Equipped with chilled water air conditioners, chilled water pre-cooling, cooling fans, and inverter-type high-efficiency equipment, it can reduce cooling power costs by more than 20% compared to before. This can reduce carbon emissions by 26,000 tons annually.

Yoon Dongsik, Head of KT Cloud/DX Business Division (Executive Vice President), said, “KT is transforming into a digital platform company based on AI, big data, and cloud, and we expect Yongsan IDC to play a pivotal role,” adding, “Through differentiated infrastructure and solutions like Yongsan IDC, KT will become the ‘best digital innovation partner’ that empowers companies to actively respond to unprecedented business environments such as untact and the digital new deal.”
