Abstract

L'invention concerne un procédé et un appareil d'attribution d'espace de mémorisation. Le procédé comprend les étapes consistant : à recevoir une demande d'occupation d'espace envoyé par un correspondant demandeur d'espace (S201); dans un cas où une capacité d'espace pré-attribuée est insuffisante, déterminer si une capacité d'espace d'un dispositif de mémorisation d'extension est suffisante (S202); et si la capacité d'espace du dispositif de mémorisation d'extension est suffisante, à attribuer un espace de mémorisation dans le dispositif de mémorisation d'extension au demandeur d'espace (S205) correspondant. En conséquence, dans le procédé et l'appareil, dans un cas où une capacité d'espace pré-attribuée est insuffisante, si une capacité d'espace d'un dispositif de mémorisation d'extension est suffisante, un espace de mémorisation dans le dispositif de mémorisation d'extension peut encore être attribué à un système afin d'être utilisé, et, par conséquent, la possibilité d'une mauvaise expérience d'utilisation d'un utilisateur due à une insuffisance d'espace de mémorisation peut être réduite.
