Tier 4 data center certification typically serve enterprise corporations and provide the following. Tier 4 is designed to host mission critical servers and computer systems with fully redundant subsystems cooling power network links storage etc and compartmentalized security zones controlled by biometric access controls methods.

However the tier 3 data center specifications require two or more power lines between each ats and power distribution panel to ensure redundancy and concurrent maintainability. What constitutes tier 4 data center ratings. Topology is a restatement of the content previously published as uptime institute publication tier classifications define site infrastructure performance. A tier iii provider can undergo routine maintenance without a hiccup in operations.
