Patent

CA 2346696

A computer system has a plurality of processors each processor (172) executing an independent operating system image without sharing file system state information. The system includes an active backplane (110) coupled to the plurality of processors; and one or more data storage devices (106, 108) coupled to the active backplane (110) for satisfying data requests from the plurality of processors, each of the data storage devices (106, 108) being adapted to secure a file when one processor (172) writes to the file and to release the file when the processor (172) completes operation on the file.

L'invention concerne un système informatique, comprenant une pluralité de processeurs, chaque processeur (172) exécutant une image indépendante du système d'exploitation, sans partager les informations d'état du système de fichiers. Le système comprend un fond de panier (110) actif couplé aux processeurs; et un ou plusieurs dispositif(s) de stockage (106, 108) de données couplé(s) au fond de panier (110) actif, afin de satisfaire des demandes de données provenant des processeurs, chaque dispositif de stockage (106, 108) de données étant conçu de façon à protéger un fichier lorsqu'un processeur (172) écrit dans ledit fichier et à libérer ce fichier lorsque le processeur (172) termine une opération sur le fichier.
