Tier Two ITE sites are characterized by what feature in their design?

In the context of data center and critical infrastructure design, Tier Two ITE (Information Technology Equipment) sites are characterized by redundancy in their infrastructure components. This means that these facilities are designed to provide a level of backup for critical systems, ensuring that operations can continue even if a primary component fails. This redundancy typically includes aspects such as power supply and cooling systems, where additional units or pathways are available to maintain functionality.

The significance of redundancy in Tier Two sites lies in the reliability it brings. It allows for planned maintenance activities and enhances overall operational resilience by reducing the risk of unplanned outages. While features like enhanced power supply, higher cooling capacity, and advanced fire suppression systems might also be present in these sites, the defining characteristic that sets Tier Two apart is its emphasis on redundancy to support continuous operations.
