Tier 1 2 3 Data Center
Data center tiers are a common way of classifying data centers according to the possible performance of their infrastructure (Tier 1 2 3 Data Center uptime). Data center tiers are ranked from Tier 1 2 3 4 Data Center, and data centers with higher rankings have more potential uptime than those with lower rankings.
Here are the four data center tier rankings that are currently recognized by the Uptime Institute. Along with an explanation of what each ranking means in terms of uptime and availability.
Who Approves Data Centres?
Either the TIA/942 standard or the Uptime Institutes’ standard tier classification scheme are typically used to rate and certify data centers. Data centers are rated after being certified against these requirements.
Make sure you are aware of their reputation in the industry and the standard they are utilizing before engaging them to certify your data center.
