Abstract

L'invention concerne un procédé de commande d’un ventilateur pour architecture informatique avancée de télécommunications (Advanced Telecom Computing Architecture, ATCA) et un gestionnaire d’armoire (Shelf Management Controller, SHMC) ATCA, tous deux susceptibles d’obtenir une stratégie de commande du ventilateur de toutes les mono-tablettes de l’armoire. Ladite stratégie de commande du ventilateur comporte l’une quelconque des trois actions consistant à accroître la vitesse de rotation du ventilateur, à réduire la vitesse de rotation du ventilateur et à maintenir constante la vitesse de rotation du ventilateur. La stratégie de commande du ventilateur de l’armoire découle des stratégies de commande de ventilateur de toutes les mono-tablettes dans l’armoire machine, la vitesse de rotation du ventilateur étant réglée en conséquence. Il est garanti que l’armoire ATCA se conforme à la stratégie de commande de ventilateur de toutes les mono-tablettes, de telle sorte que le ventilateur puisse fonctionner à la plus basse vitesse possible, ce qui réduit le bruit et la dissipation d’énergie du ventilateur, prolongeant ainsi la durée de vie en service du ventilateur.
