Abstract

La présente invention concerne un dispositif de commande de mémorisation, comportant une première unité de commande E/S pour commander la lecture de données à partir d'une ou plusieurs unités HDD et l'écriture de données dans celles-ci, une seconde unité de commande E/S dont la consommation électrique est approximativement égale à celle de la première, deux premiers dispositifs d'alimentation ou plus délivrant du courant à la première unité, deux seconds dispositifs d'alimentation ou plus délivrant du courant à la seconde unité, et au moins trois disjoncteurs recevant du courant délivré depuis l'extérieur et délivrant le courant aux premiers et seconds dispositifs d'alimentation tout en interrompant l'alimentation du courant lorsque du courant dépassant un niveau prédéfini circule. Chacun des premiers/seconds dispositifs d'alimentation inclut un circuit d'équilibrage de courant pour égaliser des courants de sortie des premiers/seconds dispositifs d'alimentation.
