Title (EN) STORAGE CONTROL APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE GESTION MÉMOIRE
Abstract: front page image
(EN)A storage control apparatus of the present invention is able to duplicatively manage data in a cache memory even during maintenance work. When a memory package CMPK3 specified by a user is removed from the apparatus 1 (S2), a microprocessor 2 changes a pair that has been configured using CMPK2 and CMPK3 to a pair of CMPK2 and a free area of a CMPK1. As a result, received data (S5) is respectively written to multiple cache memories (S6, S7), and duplicatively managed.
(FR)L'invention concerne un appareil de gestion mémoire apte à gérer par duplication des données présentes dans une mémoire cache, même lors d'une intervention de maintenance. Lorsqu'un module de mémoire CMPK3 spécifié par un utilisateur est retiré de l'appareil 1 (S2), un microprocesseur 2 modifie une paire configurée à l'aide de CMPK2 et CMPK3 pour obtenir une paire constituée de CMPK2 et d'une zone libre de CMPK1. Les données reçues (S5) sont ainsi écrites respectivement sur une pluralité de mémoires caches (S6, S7) et gérées par duplication.
