Abstract: front page image
(EN) The present invention obtains with high precision, in a storage system, the effect of additional installation or removal of cache memory, that is, the change of the cache hit rate and the performance of the storage system at that time. For achieving this, when executing normal cache control in the operational environment of the storage system, the cache hit rate when the cache memory capacity has changed is also obtained. Furthermore, with reference to the obtained cache hit rate, the peak performance of the storage system is obtained. Furthermore, with reference to the target performance, the cache memory and the number of disks and other resources that are additionally required are obtained.
(FR) La présente invention permet de connaître à un moment donné avec une grande précision dans un système de stockage l'effet de l'installation ou du retrait d'une antémémoire c,-à-d. la modification du taux de présence en antémémoire et les performances du système de stockage. A cette fin, lors de l'exécution d'une commande normale de l'antémémoire, dans l'environnement opérationnel du système de stockage, on peut également obtenir le taux de présence en antémémoire suite à une modification de la capacité de l'antémémoire. On peut en outre en se référant aux performances cibles, obtenir l'antémémoire, le nombre de disques et d'autres ressources additionnelles demandées.
