What are data center tiers? In short, they are rankings in how data centers perform. They range from I to IV, with I being the lowest performance ranking and IV being the highest. Data centers are secure, off-site locations which house servers and networking infrastructure. Companies can have their cloud-based servers stored in data centers, allowing data center services Toronto providers, like Pathway Communications to manage their IT needs.

Requirements for Tier II Data Center
While Tier II data centers provide the same features as Tier I, they also provide other more advanced options such as:
- Uninterruptable Power Supplies
- Cooling Options
- Pumps
- Generators
- Redundancy Options
They are required to offer 99.741% uptime which means less than 1,361 minutes of downtime per year.
Requirements for Tier III Data Center
