There is a standard which developed and maintained by the Telecommunications Industry Association (TIA) to define uptime of data center. The data center tier system is measuring data center performance, investment and return on investment (ROI) and there are 4 tiers in total, from tier 1 to tier 4. Here is a statistics reference of 4 data center tiers in the following:
Tier 1: Expected uptime levels of 99.671%
Tier 2: Expected uptime levels of 99.741%
Tier 3: Expected uptime levels of 99.982%
Tier 4: Expected uptime levels of 99.995%
The higher percentage the greater quality data center. Expected uptime is one of the elements to qualify a data center ranking, apart from expected or promised uptime, physical infrastructure, cooling infrastructure, power infrastructure and redundancy levels are the factors go into each tier ranking as well.
To compare with Tier 1 and Tier 2 data center, Tier 1 data center is the simplest one of 4 tiers, basically offers single uplink and servers with non-redundancy capacity components and utilized by small business in general. Tier 2 data center has more measures and infrastructure than tier 1 data center and offers single uplink and servers with redundancy capacity components. The differences between Tier 3 and Tier 4 data center are the former meets all the requirement of both tier 1 and tier 2 as well as dual-powered equipment and multiple uplinks. Tier 4 data center is the top one of 4 tiers, which is meeting all 3 tiers equipment plus offering multiple uplinks and servers with fully fault-tolerant components and typically serve enterprise corporations.
