1. ÜbersichtPS-01.03ACThe security requirements for a self-sufficient operation during a heat period are based on the highest outside temperatures that can reasonably be estimated to occur at the locations of the premises and buildings within the lifespan of the cooling supply system. The cloud service provider determines these temparatures with an appropriate safety margin.Incorrect planning can endanger the operational safety and availability of the premises or buildings. This can result from an incorrect assessment of elementary hazards at the site (e.g. air traffic, earthquakes, floods, hazardous substances) as well as an incorrect conception of the bandwidth or energy supply. Premises and buildings related to the cloud service provided include data centres and server rooms housing system components used to process cloud service customer data (including data centres for backup or redundancy purposes) and the technical utilities required to operate these system components (e.g. power supply, refrigeration, fire-fighting, telecommunications, security, etc.). Premises and buildings in which no data from cloud service customers is processed or stored (e.g. offices of the cloud service provider, server rooms with system components for internal development and test systems) adhere to requirements specifically covered under PS-08. A reasonable estimation of the highest outside temperatures can be based on information supplied by official measurement station such as Deutscher Wetterdienst (DWD) or other reliable resources, such as e.g. American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). These estimations should take the effects of global warming into account. What constitutes an appropriate safety margin depends on the location of the premises and buildings. In Germany, 3 Kelvin can generally be considered appropriate.
