Title (EN) COLLISION HANDLING DURING AN ASYNCHRONOUS REPLICATION
(FR) TRAITEMENT DE COLLISION AU COURS D'UNE RÉPLICATION ASYNCHRONE
Abstract:
(EN) Methods and systems for collision handling during an asynchronous replication are provided. A system includes a cache memory system comprising a number of cache memory pages. A collision detector detects when a host is attempting to overwrite a cache memory page that has not been completely replicated. A revision page tagger copies the cache memory page to a free page and tags the copied page as protected.
(FR) L'invention concerne des procédés et des systèmes pour le traitement de collisions au cours d'une réplication asynchrone. Un système comprend un système de mémoire cache comprenant un certain nombre de pages de mémoire cache. Un détecteur de collision détecte lorsqu'un hôte tente de réécrire une page de mémoire cache qui n'a pas été complètement répliquée. Un étiqueteur de page de révision copie la page de mémoire cache sur une page libre et étiquette la page copiée comme étant protégée.
