摘要： Method and apparatus for detecting changes in a configuration of a computer system including a host computer and at least one computer system resource. Information relating to a reference configuration of the computer system is stored at a first point in time. A current configuration of the computer system is determined at a second point in time. The current configuration of the computer system is compared with the reference configuration to determine whether the current configuration differs from the reference configuration. An indication is provided when the current configuration of the computer system differs from the reference configuration.

摘要： One aspect is directed to a method for performing data migration from a first volume to a second volume while allowing a write operation to be performed on the first volume during the act of migrating. Another aspect is a method and apparatus that stores, in a persistent manner, state information indicating a portion of the first volume successfully copied to the second volume. Another aspect is a method and apparatus for migrating data from a first volume to a second volume, and resuming, after an interruption of the migration, copying data from the first volume to the second volume without starting from the beginning of the data. Another aspect is a method and apparatus for migrating to data from a first to a second volume, receiving an access request directed to the first volume from an application that stores data on the first volume, and redirecting the access request to the second volume without having to reconfigure the application that accesses data on the first volume.

摘要： Detecting computer viruses includes providing a disk space having at least a portion that is partitioned into separate segments, each segment being accessed by at least one of a plurality of hosts. A first one of the segments is accessed using a different file system than a second one of the segments. An antivirus unit scans at least part of the disk space for viruses. The part of the disk space that is scanned by the antivirus unit includes at least some parts of the first and second segments. The first and second segments may correspond to different physical portions of the disk space. The first and second segments may or may not overlap. The first and second segments may correspond to logical entities. Part of the disk space that is scanned by the antivirus unit may correspond to particular types of files stored in the disk space. The disk space that is scanned by the antivirus unit may correspond to files that have been modified since a previous virus scan.

摘要： A method and apparatus for manipulating data in a storage device that is coupled to a host computer. Manipulations that can be performed by the storage device include moving non-contiguous blocks of data between the host computer and the storage device in a single operation. Other manipulations can be performed directly by the storage device without passing data to or from the host computer and include copying data from one logical object that is defined on the host computer to another, initializing, backing-up, transforming, or securely deleting a logical object that is defined by the host computer with a single command. In one embodiment, an application programming interface is provided that allows a relationship between logical objects on a host computer and storage locations on a storage device to be communicated between the host computer and the storage device. By providing the storage device with knowledge of the relationship between a logical object and the storage locations corresponding to that logical object, data corresponding to the logical object can be manipulated directly by the storage device, rather than by the host computer. In another embodiment, a graphical visualization routine is provided that displays the global mapping of a logical object to a set of physical blocks on the storage device for each layer of mapping below the logical object.

摘要： A method of managing information to be stored on a storage disc in a disc drive system to achieve improved system performance. Some of the data on the disc may be mirrored on the same surface of the disc to reduce latency and/or seek time. Compression techniques may be employed to limit reductions in the storage capacity of the disc. In another embodiment, data is preferentially stored on the outer tracks of the disc because system performance is greater when accessing outer tracks. Compression techniques may also be employed with this embodiment to limit reductions in the storage capacity of the disc. Compressed data stored on the disc may be transferred to another storage medium in its raw compressed form to reduce the number of instructions that would be required to transfer the data if it were decompressed before transfer.

摘要： A data management technique for managing accesses to data at a shared storage system includes a filter at the storage system. The filter is coupled to a configuration table, which identifies which of a number of coupled host processors have accesses to each of the resources at the device. During operation, requests received from the host devices are filtered by the filter, and only those requests to resources that the individual host devices have privilege to access are serviced. Advantageously, data security is further enhanced by authenticating each of the requests received by the storage system to verify that the host processor that is represented as forwarding the request is the indicated host processor. In addition, transfers of data between the storage system and the host processor may be validated to ensure that data was not corrupted during the data transfer.
