Title (EN) A METADATA CONTROL IN A LOAD-BALANCED DISTRIBUTED STORAGE SYSTEM
(FR) COMMANDE DE MÉTADONNÉES DANS UN SYSTÈME DE MÉMORISATION DISTRIBUÉE ÉQUILIBRÉ EN CHARGE
Abstract:
(EN) A plurality of computing devices are communicatively coupled to each other via a network, and each of the plurality of computing devices is operably coupled to one or more of a plurality of storage devices. A plurality of failure resilient address spaces are distributed across the plurality of storage devices such that each of the plurality of failure resilient address spaces spans a plurality of the storage devices. The plurality of computing devices maintains metadata that maps each failure resilient address space to one of the plurality of computing devices. The metadata is grouped into buckets. Each bucket is stored in a group of computing devices. However, only the leader of the group is able to directly access a particular bucket at any given time.
(FR) Une pluralité de dispositifs informatiques sont couplés en communication entre eux par l'intermédiaire d'un réseau, et chaque dispositif informatique parmi la pluralité de dispositifs informatiques est couplé fonctionnellement à un ou plusieurs dispositifs parmi une pluralité de dispositifs de mémorisation. Une pluralité d'espaces d'adressage tolérants aux défaillances est distribuée parmi la pluralité de dispositifs de mémorisation de sorte que chaque espace d'adressage parmi la pluralité d'espaces d'adressage tolérants aux défaillances couvre une pluralité de dispositifs de mémorisation. La pluralité de dispositifs informatiques maintient des métadonnées qui mappent chaque espace d'adressage tolérant aux défaillances à un dispositif parmi la pluralité de dispositifs informatiques. Les métadonnées sont regroupées en compartiments. Chaque compartiment est mémorisé dans un groupe de dispositifs informatiques. Cependant, seul le chef du groupe peut accéder directement à un compartiment particulier à moment donné quelconque.
