Information technology - Data centre facilities and infrastructures - Part 4-2: Power Usage Effectiveness

This European Standard specifies the Power Usage Effectiveness (PUE) as a Key Performance Indicator (KPI) to quantify the efficient use of energy in the form of electricity. NOTE See the Note 1 to entry in Definition 3.1.3. This European Standard: a) defines the Power Usage Effectiveness (PUE) of a data centre; b) introduces PUE measurement categories; c) describes the relationship of this KPI to a data centre’s infrastructure, information technology equipment and information technology operations; d) defines the measurement, the calculation and the reporting of the parameter; e) provides information on the correct interpretation of the PUE. PUE derivatives are described in Annex C.

NOTE Voir la Note 1 à l'article de la Définition 3.1.3. La présente Norme européenne: a) définit l’efficacité de l'utilisation de l'énergie (PUE) d’un centre de traitement de données; b) introduit les catégories de mesure du PUE; c) décrit la relation de ce KPI avec une infrastructure de centre de traitement de données, des équipements de traitement de l’information et des opérations de traitement de l’information; d) définit le mesurage, le calcul et les rapports du paramètre; e) fournit des informations sur l’interprétation correcte du PUE. Les dérivés du PUE sont décrits dans l’Annexe C.

Informacijska tehnologija - Naprave in infrastruktura podatkovnih centrov - 4-2. del: Učinkovitost porabe energije

Ta evropski standard določa učinkovitost porabe energije (PUE) kot bistveni kazalnik učinkovitosti (KPI) za kvantifikacijo učinkovite porabe energije v obliki elektrike.
OPOMBA:   Glej opombo 1 glede vnosa v definiciji 3.1.3.
Ta evropski standard:
a)   določa učinkovitost porabe energije podatkovnega centra;
b)   uvaja merilne kategorije učinkovitosti porabe energije;
c)   opisuje razmerje tega bistvenega kazalnika učinkovitosti z infrastrukturo podatkovnega centra, opremo informacijske tehnologije in delovanjem informacijske tehnologije;
d)   opredeljuje merjenje, izračun in poročanje parametra;
e)   podaja informacije o pravilni interpretaciji učinkovitosti porabe energije.
Izpeljanke učinkovitosti porabe energije so opisane v dodatku C.
