The present invention provides a system and method for managing quality of service for a storage system that includes several file systems that share resources. The system may include a Quality of Service (QoS) manager and a request limitation process or "throttle" for limiting requests to the file systems based on measured operational data. The QoS manager employs various methods for managing quality of service including controlling memory usage of clean pages and other resources, admission control, and controlling the rate at which modified buffers are written to disk.
L'invention concerne un système et un procédé de gestion de la qualité de service pour un système de stockage qui comprend plusieurs systèmes de fichiers partageant des ressources. Le système peut comprendre un gestionnaire de qualité de service (QdS) et un procédé de limitation de requête ou "régulateur" qui permet de limiter les requêtes pour les systèmes de fichiers en fonction de données opérationnelles mesurées. Le gestionnaire QdS emploie divers procédés de gestion de qualité de service, notamment la commande de l'utilisation de la mémoire de pages propres et d'autres ressources, la commande d'admission, et la commande de la vitesse à laquelle des tampons modifiés sont inscrits sur un disque.
