Abstract | A distributed data storage system stores a single image file system across a plurality of physical storage volumes. The physical storage may be direct attached storage, or may be coupled through a storage area network ("SAN"). One or more clients communicate with a plurality of storage nodes through a network. A client of the distributed data storage system transmits a request over the network for a file identified in the file system. A load-balancing switch selects one of the storage nodes to process the request. The storage node accesses at least one of the physical volumes and transmits a response for the storage operation to the client.
L'invention concerne un système mémoire de données réparties mettant en mémoire un système de fichier d'image unique à travers plusieurs volumes de mémoire physique. La mémoire physique peut consister en une mémoire directement associée, ou peut être couplée à travers un réseau de zone mémoire ( </= SAN >/= ). Un ou plusieurs clients communiquent avec ces noeuds de mémoire à travers un réseau. Un client du système mémoire de données réparties transmet une demande via le réseau pour un fichier identifié dans le système de fichier. Un commutateur d'équilibrage des charges sélectionne un des noeuds de mémoire en vue de traiter la demande. Le noeud de mémoire accède à au moins un des volumes physiques et transmet une réponse en vue de permettre au client l'opération de mise en mémoire. |
