Abstract: front page image
(EN)Conventionally, the fees for using services of a storage system was calculated based on the status of use or access performance of storage areas and not based on migration of data. The present invention provides a storage system in which multiple tiers composed of storage areas of various memory devices are assigned in page units and the assigned tiers are changed based on access frequency, wherein stored costs are calculated based on status of use of the storage areas constituting the tiers, and migration costs are calculated and charged based on the amount of migration of data among tiers and the I/O access counts after migration, according to which appropriate charging of cost for using the storage system is enabled.
(FR)De manière conventionnelle, des taxes d'utilisation de services d'un système de stockage étaient calculées sur la base de l'état de performances d'utilisation ou d'accès et non sur la base d'une migration de données. La présente invention concerne un système de stockage dans lequel multiples niveaux composés de zones de stockage de divers dispositifs de mémoire sont assignés dans des unités de page et les niveaux assignés sont changés sur la base de la fréquence d'accès, les coûts de stockage étant calculés sur la base de l'état d'usage des zones de stockage constituant les niveaux tandis que les coûts de migration sont calculés et imputés sur la base du volume de migration des données parmi les niveaux et sur la base des comptes d'accès d'E/S après la migration, selon l'imputation appropriée des coûts pour l'utilisation du système de stockage qui est permise.
