Stellium 2 and Stellium 3

Stellium 2 and Stellium 3 datacenters have been designed to achieve high-power density and world-class PUE efficiency, and are provided with N+N primary electrical power from diverse sources.

The data halls operate without IT raised floors. Instead, the cooling infrastructure is designed in accordance with DAO/IDAO technology, and is capable of delivering a PUE of 1.15 when operated within ASHRAE-recommended temperature and humidity parameters.

All data halls are provided with independent engineering-plant space that meets the Tier III+ datacenter design standard of concurrent maintainability and diverse infrastructure paths. Additional shared services, including customer setup and decommissioning, catering, and car-parking facilities are available.

Stellium 2 covers an area of 3,600m2, divided into four separate IT data halls: two with an area of 960m2, and two with an area of 840m2.

Stellium 3 covers an area of 2,400m2, divided into four separate IT data halls, each with an area of 600m2.
