| 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. |

The space where telecommunications cables (from outside providers) enter the building. It houses demarcation points and typically contains access provider equipment. It should be separate from the Computer Room for security and to prevent environmental cross-contamination. tia-942-b

The primary space where data processing equipment is located. It requires strict environmental control, raised flooring (or overhead distribution), and optimized airflow. | Rating | Description | Redundancy | Impact
