Abstract

L'invention concerne des procédés et des systèmes pour gérer un dispositif de stockage. Dans une mise en oeuvre, un dispositif d'attribution de stockage qui est présent dans un hôte ou un dispositif de stockage reçoit une demande pour stocker un fichier dans une zone de stockage du dispositif de stockage. Le dispositif d'attribution de stockage marque le fichier comme jetable dans une structure de système de fichiers associée au dispositif de stockage et met à jour une table d'attributions de fichiers primaires ("FAT") pour associer une chaîne de grappes qui est attribuée au fichier avec le fichier. Le dispositif d'attribution de stockage met de plus à jour une FAT jetable ou une base de données pour représenter un emplacement physique du fichier, ou peut générer un ou plusieurs fichiers d'emplacement qui stockent l'emplacement physique du fichier. Le dispositif d'attribution de stockage gère ensuite le dispositif de zone de stockage en fonction de la FAT et d'une FAT jetable, d'une base de données ou d'un ou plusieurs fichiers d'emplacement indiquant l'emplacement physique du fichier.
