Equinix SG4 IBX Data Center

Status: Operational (Completed Phase I - Continual Efficiency Upgrades)   |   Location: 7 Tai Seng Drive, Singapore, Singapore 535218

Project Overview

Equinix SG4 stands as a premier example of how Singapore, despite being land- and power-constrained, manages to maintain its status as one of the world's most critical data center hubs through hyper-efficiency and high interconnection density. Located in the Tai Seng industrial area, SG4 was an $\approx \mathbf{USD} \mathbf{90}$ million investment completed in February 2020, providing space for over 4,000 cabinets and serving as the fourth major International Business Exchange (IBX) for Equinix in the city-state.The facility’s importance lies not just in its size but in its role as a dense interconnection hub, facilitating direct, low-latency connections between a vast ecosystem of cloud providers, network carriers, financial institutions, and major enterprises a signature strength of the Equinix platform. Technically, SG4 is designed for maximum resilience, featuring 2N electrical redundancy and N+1 cooling redundancy, meeting the stringent requirements for high-availability cloud and financial services workloads.

The typical power density of $\approx 4.5\text{ kVA}$ per cabinet reflects the demand for compact, powerful infrastructure in this premium market.Crucially, SG4’s story is one of continuous "Greenovation." Singapore’s government has set a firm PUE target of $\le 1.3$ for new and existing facilities, pushing operators to adopt advanced cooling techniques. Equinix has actively engaged in this effort, continuously fine-tuning its high-efficiency water-cooled chiller system by increasing the chilled water supply temperature and optimizing air handling units. This commitment to efficiency allowed SG4 to upgrade its sustainability rating to the prestigious Green Mark Platinum in 2023, showcasing how world-class data centers in challenging tropical climates can meet and exceed rigorous environmental standards, a model for sustainable digital growth across the Asia-Pacific region.
