Initially, the classification of data centers may not seem crucial, as they all serve the same purpose of hosting IT equipment. However, different categories of data centers offer varying levels of availability, uptime, and specialized services like “white-glove” management. Understanding these distinctions is vital for aligning your data center choice with your business requirements, performance expectations, and financial constraints.
Primary Data Center Classification Methods
There are multiple ways to classify data centers, with the most common types outlined below.
1. Tiers
The tier system, developed by the Uptime Institute, is a widely recognized classification method for data centers. It focuses on reliability and uptime guarantees, with higher tiers indicating greater redundancy against potential downtime from various infrastructure issues.
Data centers seeking tier certification undergo rigorous analysis by the Uptime Institute to validate their design, construction, and operational sustainability. It’s essential to verify official certification to ensure reliability guarantees.
2. Power Capacity
Another common classification criterion is based on power consumption, typically measured in megawatts. While this indicates the scale of a data center, it does not directly correlate with other operational aspects like reliability or sustainability.
3. Sustainability Certification
Data centers can also be differentiated based on sustainability certifications like LEED and ISO 50001. While these certifications focus on energy efficiency, they may not encompass individual equipment configurations or energy sourcing.
4. Data Center Service Model
Data centers can be categorized based on services offered, such as private data centers serving specific companies, or colocation centers providing shared hosting space. Colocation is often preferred for its flexibility and global workload distribution capabilities.
5. Size
Lastly, data centers can be described based on size, including hyperscale facilities, traditional large centers, modular setups, and micro data centers. These size classifications provide a quick overview of a data center’s hosting capacity.
