Gestion de l'alimentation dans le centre de donn\u00e9es<\/h1>\n

Les centres de donn\u00e9es sont d'importants consommateurs d'\u00e9nergie et deviennent l'un des principaux pollueurs de gaz \u00e0 effet de serre au monde. Dans un effort pour \u00e9quilibrer la conscience \u00abverte\u00bb avec le retour sur investissement, nous pr\u00e9sentons quelques recommandations cl\u00e9s pour am\u00e9liorer la consommation d'\u00e9nergie, dans l'ensemble gestion de centre de donn\u00e9es<\/a>et efficacit\u00e9.<\/p>\n

Mesurer l'efficacit\u00e9 \u00e9nerg\u00e9tique du centre de donn\u00e9es<\/span><\/h2>\n

Afin d'\u00e9valuer les avantages potentiels de la mise en \u0153uvre de nouvelles pratiques de gestion de l'\u00e9nergie, il est n\u00e9cessaire d'identifier, de surveiller et de mesurer tous les aspects de la consommation d'\u00e9nergie dans le centre de donn\u00e9es. The Green Grid<\/a>, une association de professionnels de l'informatique cherchant \u00e0 sensibiliser \u00e0 l'efficacit\u00e9 des datacenters, a d\u00e9velopp\u00e9 une norme de m\u00e9triques pour aider les organisations \u00e0 mesurer l'efficacit\u00e9 \u00e9nerg\u00e9tique de leurs datacenters. Les mesures d'efficacit\u00e9 \u00e9nerg\u00e9tique (PUE) et d'efficacit\u00e9 des centres de donn\u00e9es (DCE) permettent aux entreprises d'estimer rapidement l'efficacit\u00e9 \u00e9nerg\u00e9tique de leurs centres de donn\u00e9es, de les comparer \u00e0 d'autres centres de donn\u00e9es et de d\u00e9terminer si des am\u00e9liorations de l'efficacit\u00e9 doivent \u00eatre apport\u00e9es. Voir le sch\u00e9ma ci-dessous:<\/p>\n

Gestion de la consommation d'\u00e9nergie du centre de donn\u00e9es<\/figcaption><\/figure>\n

La surveillance de la consommation d'\u00e9nergie dans le centre de donn\u00e9es fournit une r\u00e9f\u00e9rence pour le calcul du retour sur investissement des nouveaux processus d'\u00e9conomie d'\u00e9nergie et permet d'identifier les domaines d'opportunit\u00e9.<\/p>\n

D\u00e9sactiver l'\u00e9quipement inactif<\/span>
\nThe typical x64 server consumes between 30% and 40% of its maximum power when not in use. Since all servers need not be operational 24\/7, it makes sense that individual servers should be turned off for certain periods. For example, servers executing backups are typically run only at night or during off peak hours, and test servers are not always needed on a continual basis. Data center management should assess the server utilization patterns and create a schedule to efficiently power on servers only when they are needed. Also, consider the power consumption of non-IT equipment such as air conditioning and lighting when they are not in use.<\/p>\n

Utiliser un logiciel de gestion de l'alimentation<\/span><\/h2>\n

La plupart du mat\u00e9riel informatique du centre de donn\u00e9es poss\u00e8de des fonctionnalit\u00e9s de gestion de l'alimentation int\u00e9gr\u00e9es qui ne sont jamais utilis\u00e9es. Par exemple, les processeurs de serveur ont des fonctionnalit\u00e9s de gestion de l'alimentation int\u00e9gr\u00e9es qui peuvent r\u00e9duire la puissance lorsque le processeur est inactif, en baissant leur tension d'entr\u00e9e et leur fr\u00e9quence en fonction de l'utilisation des t\u00e2ches en cours. Gestion du centre de donn\u00e9es<\/a> n'a pas enti\u00e8rement adapt\u00e9 ces types de fonctionnalit\u00e9s car l'impact sur la disponibilit\u00e9 n'est pas clair. Au fur et \u00e0 mesure que davantage d'outils deviennent disponibles avec des fonctionnalit\u00e9s de gestion de l'\u00e9nergie et que les donn\u00e9es montrent que les performances ne sont pas affect\u00e9es, cette technologie gagne en popularit\u00e9 sur le march\u00e9. Profiter de ces fonctionnalit\u00e9s peut consid\u00e9rablement r\u00e9duire la consommation d'\u00e9nergie des serveurs sur le long terme.<\/p>\n

Utilisez des blocs d'alimentation efficaces<\/span>
\n<\/span>De nombreuses alimentations de serveurs dans les centres de donn\u00e9es fonctionnent aujourd'hui avec une efficacit\u00e9 inf\u00e9rieure \u00e0 celle qui est actuellement disponible. L'US EPA a estim\u00e9 l'efficacit\u00e9 moyenne des alimentations de serveur install\u00e9es \u00e0 72%<\/a>. Les meilleures alimentations de sa cat\u00e9gorie sont disponibles aujourd'hui et offrent une efficacit\u00e9 de 90%. Les organisations qui am\u00e9liorent l'efficacit\u00e9 \u00e9nerg\u00e9tique de leurs unit\u00e9s d'alimentation \u00e9lectrique peuvent augmenter l'efficacit\u00e9 de l'ensemble de leur infrastructure de distribution d'\u00e9nergie.<\/p>\n
