Iron Mountain has topped out a new data center in Chennai, India.

“We are thrilled to celebrate a recent major milestone in our global expansion: the official topping-out ceremony of our Chennai CHN-1 data center in Ambattur!” the company said on LinkedIn this week. “As the structural framework reaches its highest point, we are one step closer to bringing 23.2MW of total power capacity to one of India’s most vital digital hubs.”

At full build-out, the two-building campus will offer 42MW of capacity across 800,000 sq ft (74,322 sqm). The first building is set to go live later this year.

Iron Mountain has around 415MW of colocation and hyperscale capacity in 21 markets across seven countries and three continents.

Iron Mountain first entered India in 2021, setting up a joint venture with Web Werks. Last year, the company acquired Web Werks, taking over a portfolio of six data centers located in five Indian markets - Mumbai, Bangalore, Hyderabad, Pune, and Noida - with a total IT capacity of 14MW. The deal also included in-development projects in Mumbai, Chennai, and Noida, totaling 142MW.

The 4.3-acre campus is located in the Ambattur area of Chennai. The second building, the 19MW CHN-2, is expected to go live in 2028.

Chennai is one of India's major data center markets. Other operators present around the Tamil Nadu city include STT GDC, Equinix, Sify, CtrlS, Colt, PDG, Digital Realty's Digital Connexion, NTT, AdaniConneX, and others.
