Die Stromverbrauchseffektivit\u00e4t (Power Usage Effectiveness, PUE) ist eine Kennzahl, die zur \u00dcberpr\u00fcfung und Verbesserung der Energieeffizienz im Rechenzentrumsbetrieb verwendet wird.<\/p>\n

Der PUE-Wert bewertet die Leistung des Rechenzentrums, indem er das Verh\u00e4ltnis zwischen dem Energieverbrauch des gesamten Rechenzentrums und dem Energieverbrauch der IT-Ger\u00e4te berechnet.<\/p>\n

Der PUE-Wert ist definiert als das Verh\u00e4ltnis von zwei Zahlen: die Eingangsleistung des Rechenzentrums im Verh\u00e4ltnis zur Stromversorgung der IT-Last.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Die Gesamtleistung der Einrichtung umfasst die gesamte Energie der IT-Ausr\u00fcstung, wie im vorherigen Punkt beschrieben, sowie alles, was die IT-Ausr\u00fcstung unterst\u00fctzt und Energie verbraucht, wie z. B.:<\/p>\n

    \n
  • \u00a0Stromversorgungskomponenten, einschlie\u00dflich USV-Systeme, Schalttafeln, Generatoren, Stromverteilungseinheiten (PDUs), Batterien und Verteilungsverluste au\u00dferhalb von IT-Ger\u00e4ten<\/li>\n
  • K\u00fchlsystemkomponenten wie K\u00e4ltemaschinen, K\u00fchlt\u00fcrme (in unserem Fall nicht vorhanden), Pumpen, L\u00fcftungsger\u00e4te (AHU), Klimager\u00e4te f\u00fcr Computerr\u00e4ume (CRAC) und Direktexpansionsluft (DX), W\u00e4rmepumpen usw.<\/li>\n
  • Andere Lasten diverser Komponenten, wie z. B. die Beleuchtung von Rechenzentren<\/li>\n<\/ul>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
    \n\t\t
    \n\t\t\t

    Die Energie der IT-Ausr\u00fcstung umfasst die Energie, die mit der gesamten IT-Ausr\u00fcstung (z. B. Computer-, Speicher- und Netzwerkausr\u00fcstung) sowie mit zus\u00e4tzlichen Ger\u00e4ten (z. B. Switches, Monitore und Workstations\/Laptops, die zur \u00dcberwachung oder anderweitigen Steuerung des Rechenzentrums verwendet werden) verbunden ist.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

    Saisonaler PUE-Wert<\/h2>
    <\/div><\/div>\n\t
    \n\t\t
    \n\t\t\t

    Die Berechnung des saisonalen PUE-Wertes erfolgt unter Ber\u00fccksichtigung der Schwankungen der klimatischen Bedingungen (Au\u00dfentemperatur) im Laufe des Jahres, was zu Schwankungen bei der thermischen Belastung des Geb\u00e4udes und folglich zu Schwankungen bei der elektrischen Belastung f\u00fchrt, und unterscheidet sich damit von der vorherigen Berechnung des Spitzen-PUE-Wertes<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

    \n\t\t
    \n\t\t\t

    Betrachtet man den t\u00e4glichen st\u00fcndlichen Lastgang (bezogen auf jeden Monat), so muss in der Regel f\u00fcr ein Rechenzentrum eine Simulation durchgef\u00fchrt werden.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"PUE Peak Power Usage Effectiveness (PUE) ist eine Kennzahl, die zur \u00dcberpr\u00fcfung und Verbesserung der Energieeffizienz im Rechenzentrumsbetrieb verwendet wird.
