Selon une \u00e9tude r\u00e9cemment publi\u00e9e par l'universit\u00e9 de Stanford et Anthesis Group, environ un tiers de tous les serveurs exploit\u00e9s dans les centres de donn\u00e9es ne sont pas n\u00e9cessaires et sont donc des consommateurs d'\u00e9nergie inutiles.<\/p>\n

L'\u00e9tude qualifie ces serveurs de \"comateux\" et a estim\u00e9 \u00e0 quatre gigawatts les besoins \u00e9nerg\u00e9tiques mondiaux de ces syst\u00e8mes.<\/p>\n

Les principales causes de l'apparition de tels serveurs zombies sont l'exploitation d'applications inutilis\u00e9es ou redondantes, des applications qui ne continuent \u00e0 fonctionner que pour des raisons \"historiques\" ou des applications int\u00e9gr\u00e9es dans des processus complexes que plus personne ne comprend dans l'entreprise. Pour de telles applications \"mortes\", il se peut m\u00eame que plusieurs serveurs morts-vivants soient alors utilis\u00e9s.<\/p>\n

\"La consommation d'\u00e9nergie insens\u00e9e n'est qu'un probl\u00e8me r\u00e9sultant de l'exploitation de serveurs zombies\"<\/em><\/p>\n

explique Peter D\u00fcmig, Senior Server Product Manager chez Dell \u00e0 Francfort-sur-le-Main.<\/p>\n

\"Dans la gestion du syst\u00e8me, ces syst\u00e8mes sont bien s\u00fbr pris en compte : Ils sont g\u00e9r\u00e9s, maintenus disponibles, des sauvegardes sont effectu\u00e9es, voire m\u00eame des mises \u00e0 jour. <\/em><\/p>\n

Et si les choses tournent mal, le mat\u00e9riel zombie est r\u00e9guli\u00e8rement renouvel\u00e9 dans le cadre des cycles d'approvisionnement r\u00e9guliers. Au final, il en r\u00e9sulte une charge de travail importante et des co\u00fbts consid\u00e9rables sans aucun avantage. <\/em><\/p>\n

Et si nous parlons ici d'environ 25 \u00e0 40 pour cent de tous les serveurs d'un centre de donn\u00e9es, il ne s'agit vraiment pas de peanuts\".<\/em><\/p>\n

Zombies virtuels<\/h3>\n

La virtualisation n'est pas la r\u00e9ponse au ph\u00e9nom\u00e8ne des serveurs zombies, car ce qui n'est pas n\u00e9cessaire ne doit pas \u00eatre virtualis\u00e9 ; cela ne ferait que d\u00e9placer le probl\u00e8me \u00e0 un autre niveau.<\/p>","protected":false},"excerpt":{"rendered":"
