A Tier 2 data centre builds upon the foundation of Tier 1 by incorporating partial redundancy for power and cooling systems, reducing the likelihood of service interruptions. These facilities guarantee a 99.741% uptime, which translates to about 22 hours of annual downtime. While they provide improved reliability over Tier 1, they are still not fully fault-tolerant and are unsuitable for mission-critical applications. Tier 2 data centres cater to businesses that need moderate reliability but are not ready to invest in higher-tiered infrastructure.
Tier 2 includes partial redundancy for power and cooling systems, offering improved reliability over Tier 1.
