Chennai Colocation FAQs

Why is Chennai an important Indian data center market?
Chennai is among India's top three data center markets alongside Mumbai and Bengaluru. Market size is approximately 202.43 MW in 2025, growing at 22.18% CAGR to 551.15 MW by 2030. The city's coastal position makes it the natural landing point for submarine cables — five existing cable landing stations with three more planned.
What submarine cables land in Chennai?
NTT DATA's MIST (Malaysia, India, Singapore Transit) submarine cable system landed at NTT's Chennai station in May 2023 — 8,100 km, 200+ Tbps capacity, connecting Malaysia, India, Singapore and Thailand. Bharti Airtel landed SEA-ME-WE 6 (SMW6) in Chennai. The combination makes Chennai uniquely positioned for pan-Asia and EU-Asia connectivity.
Where are Chennai's data centers concentrated?
Three main clusters: (1) East Coast / Cable Landing Zone — facilities adjacent to submarine cable landings, optimised for cable-dependent workloads, (2) OMR (Old Mahabalipuram Road) IT Corridor — enterprise ecosystem serving tech tenants, (3) Outer Metro — hyperscale campuses with land for expansion.
How does Chennai compare to Mumbai?
Mumbai is larger (1.34 GW vs 202 MW) and has the financial trading ecosystem. Chennai wins for submarine cable connectivity (5+ landing stations), lower power costs, and strong enterprise tech ecosystem along OMR. Many Indian operators run dual-region active-active across Mumbai + Chennai for redundancy and latency optimisation.
Is Chennai good for AI workloads?
Yes — particularly for cost-sensitive AI workloads. Chennai's lower power costs, cable connectivity to Singapore, and growing capacity from STT GDC, NTT, AdaniConneX make it competitive. NTT Bengaluru 4 (100 MW total facility load, 67.2 MW critical IT) shows the scale of upcoming capacity in the region.
