    Abstract: Systems and methods of providing spatial security of data stored on a hard disk drive. A method includes associating a user with at least one track and/or sector of the hard disk drive. The method also includes locking the at least one track and/or sector as a default setting. The method additionally includes determining the user has moved into a predefined area. The method further includes unlocking the at least one track and/or sector based on the determining the user has moved into the predefined area.

    Abstract: A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to optimize data remanence over hybrid disk clusters using various storage technologies, determine one or more data storage technologies accessible by a file system, and determine secure delete rules for each of the one or more storage technologies accessible by the file system. The secure delete rules include a number of overwrites required for data to be securely deleted from each of the one or more storage technologies. The programming instructions are further operable to provide the secure delete rules to the file system upon a request for deletion of data for each of the one or more storage technologies a specific amount of times germane to secure delete data from the one or more storage technologies.

    Abstract: Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and in response to the secure deletion of the file not being complete during the disconnection event, indicating on a table a remote inode number assigned to the copy associated with the file at the home site, a name under which the copy is saved, and a list of data chunk tuples specifying selected data of the copy to undergo secure deletion.

    Abstract: Various embodiments intelligently cache data in distributed clustered file systems. In one embodiment, a set of file system clusters from a plurality of file system clusters being accessed by an information processing system is identified. The information processing system resides within one of the plurality of file system clusters and provides a user client with access to a plurality of files stored within the plurality of file system clusters. One or more file sets being accessed by the information processing system are identified for each of the set of file system clusters that have been identified. A set of data access information comprising at least an identifier associated with each of the set of file system clusters and an identifier associated with each of the one or more file sets is generated. The set of data access information is then stored.
