STT Chennai 2 anchors ST Telemedia Global Data Centres' Ambattur campus in Chennai, the operator's largest single building in the city at 26 MW of IT load. The operator markets it as India's largest data centre in a production environment, though that claim reflects STT GDC's own positioning rather than an independently audited ranking. The facility holds both LEED Gold certification for its environmental design and TIA-942 Rated 3 for its infrastructure resiliency, a certification pairing not every Chennai colocation site carries. Physical security runs six layers deep with round-the-clock monitoring, and the site keeps 2.7 million litres of water in on-site storage for cooling and fire systems, a scale of reserve capacity aimed at multi-day operational continuity. STT Chennai 2 sits alongside three sister buildings on the same Ambattur cluster (Chennai 1, 3 and 4), part of a broader INR 4,200 crore, roughly 130 MW multi-campus expansion the operator has announced across Ambattur and its separate Siruseri site in Chennai.
