One word that you often see associated with any data center is its “tier,” or its level of service. Virtually every data center has a tier ranking of I, II, III, or IV, and this ranking serves as a symbol for everything it has to offer: its physical infrastructure, its cooling, power infrastructure, redundancy levels, and promised uptime. This presentation takes a look at each of the 4 data center tiers, examining the key components for each tier, as well the total expected uptime level for each tier. If you are in the process of evaluating data centers, this is no doubt a term you will come across in your search, so we hope this presentation helps provide some solid background in to how you can better choose a data center for your specific needs.
