| Rating | Description | Redundancy | Impact of Failure | | :--- | :--- | :--- | :--- | | | Basic capacity infrastructure | None (N) | The data center is susceptible to disruption from both planned and unplanned activity. | | Rated-2 (Redundant) | Redundant capacity components | N+1 | Less susceptible to disruption; planned maintenance might cause downtime. | | Rated-3 (Concurrently Maintainable) | Concurrently maintainable infrastructure | N+1 | Allows for planned maintenance without downtime, but unplanned failures may still cause outages. | | Rated-4 (Fault Tolerant) | Fault-tolerant infrastructure | 2(N+1) | Provides redundancy for all components; allows for planned maintenance and unplanned failures without impact to the critical load. | tia-942-b
