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;
c) can be referred to for covering further infrastructures, e.g. telecommunications cabling;
d) defines the measurement and calculation of the metrics and resilience levels (RLs);
e) targets maintainability, recoverability and vulnerability;
f) provides examples for calculating these KPIs for the purpose of analytical comparison of different DCIs.
