Tier 4 data center certification typically serve enterprise corporations and provide the following: 99.995% uptime per year (Tier 4 uptime) 2N+1 fully redundant infrastructure (the main difference between tier 3 and tier 4 data centers) 96-hour power outage protection Tier IV Data Centers have capability levels designed to host “mission-critical” servers and computer systems. The classification levels of data centers represent a certification of design. Much of the controversy happened between the Tier III and Tier IV rankings. Although a Tier 4 data centre is more complex than a Tier 1 data centre, this does not necessarily mean it is best-suited for a business's needs. Companies who need access to their data without downtime could use a Tier 2 level data center.
