Title
(EN) METHOD AND SYSTEM TO ALTER A CACHE POLICY IN RESPONSE TO TRANSITIONS FROM AC TO DC POWER SOURCES OR FROM DC TO AC POWER SOURCES
(FR) PROCEDE ET SYSTEME POUR MODIFIER UNE POLITIQUE D'ANTEMEMOIRE
Abstract
(EN)
Briefly, in accordance with an embodiment of the invention, a system and method to alter a cache policy of the system in response to the system transitioning from a first power state to a second power state is provided. The system may include a non-volatile disk cache and a disk memory, wherein the cache policy is used by the non-volatile disk cache to cache information for the disk memory.
(FR)
Dans un mode de réalisation, l'invention concerne un système et un procédé pour modifier une politique d'antémémoire du système, en réponse au passage du système d'un premier état de puissance à un deuxième état de puissance. Le système selon l'invention peut comprendre une antémémoire de disque non volatile ainsi qu'une mémoire de disque, la politique d'antémémoire étant utilisée par la mémoire de disque non volatile pour mettre en antémémoire des informations pour la mémoire de disque.
