20120192270 | CLUSTERED FILESYSTEMS FOR MIX OF TRUSTED AND UNTRUSTED NODES - A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem. At least one trusted metadata server assigns a mandatory access control label as an extended attribute of each filesystem object regardless of whether required by a client node accessing the filesystem object. The mandatory access control label indicates the sensitivity and integrity of the filesystem object and is used by the trusted metadata server(s) to control access to the filesystem object by all client nodes. | 07-26-2012 |
20120191654 | CLUSTERED FILESYSTEM WITH DATA VOLUME SNAPSHOT MAINTENANCE - A computer system with read/write access to storage devices creates a snapshot of a data volume at a point in time while continuing to accept access requests to the mirrored data volume by copying before making changes to the base data volume. Multiple snapshots may be made of the same data volume at different points in time. Only data that is not stored in a previous snapshot volume or in the base data volume are stored in the most recent snapshot volume. | 07-26-2012 |
