Overview
This document a) defines metrics as key performance indicators (KPIs) for resilience, dependability, fault tolerance and availability tolerance for data centres; b) covers the data centre infrastructure (DCI) of power distribution and supply, and environmental control; however, it can also be used for further infrastructures, such as telecommunications cabling; c) defines the measurement and calculation of the metrics and resilience levels (RLs); d) targets maintainability, recoverability and vulnerability; e) provides examples for calculating these KPIs for the purpose of analytical comparison of different DCIs. This document does not apply to IT equipment, cloud services, software or business applications. This document is used in the design process to analyze various implementation options for power supply and distribution as well as air conditioning systems a priori in terms of their availability, in order to determine the design with the highest availability, taking into account the planned systems and components. This makes it possible to determine the optimum solution for the desired availability from this perspective before the cost-intensive procurement and implementation takes place.
