  • Patent number: 9047467
    Abstract: A method, system and apparatus for assembling and publishing frequent malware signature definition updates through the use of additive or “streaming” definition packages is provided. Embodiments of the present invention provide such functionality by publishing not only full malware signature definition updates on a long periodicity but also streaming malware signature definition updates containing newly certified signature definitions on a short periodicity. As newly-certified malware signature definitions are received, those newly-certified signature definitions are incorporated not only in the full signature definition file but also in a streaming signature definition update that contains only newly-certified signature definitions received during a streaming update period. At the end of the streaming update period, a streaming signature definition file is made available by publication to anti-malware clients.

  • Patent number: 8984175
    Abstract: A method and apparatus for providing a multipathing connection to a storage volume, where in one embodiment, the invention prohibits the disk driver from reading the storage parameter information (e.g., table of contents) upon initialization. The method commences with a multipathing disk driver determining at least on active port and at least on passive port for the storage volume. The disk driver then sends a request via the active port to the storage volume for the storage parameter information that is contained in the disk array. After the host computer's operating system disk driver receives the storage parameter information, it copies the information and distributes the information to the port definitions for the passive ports. Consequently, the ports are defined without causing a failover within the storage volume.

  • Patent number: 8954393
    Abstract: System and method for the opportunistic allocation of copies of data across data storage resources in file systems. Embodiments may opportunistically and transparently trade storage space in a file system for performance. In embodiments, when data is stored to the file system, copies of the data may be opportunistically stored to two or more data storage resources. The data may then be opportunistically accessed from a less active resource if the resource storing a primary copy of the data is busy. The opportunistically stored copies of data remain online in the file system. In hierarchical file systems or tiered storage hierarchies, embodiments may allow higher-level storage tiers to “borrow” performance from lower-level tiers by opportunistically allocating copies of data from a higher-level tier within a lower-level tier. Copies of data stored on a data storage resource may be deleted if storage space is needed on that data storage resource.

  • Patent number: 8935281
    Abstract: A method, system, computer system, and computer-readable medium to search contents of a large number of files. Data are read sequentially from a storage device without using a file system. Physical location information for the files is obtained and used to construct files from the data read. Such physical location information can be obtained, for example, by accessing a file system mapping catalog without causing the file system to read the files. Accessing the mapping catalog can be performed quickly because only metadata is read from the mapping catalog. The constructed files can then be searched for content without the overhead of the file system. Content such as virus signatures and keywords can therefore be discovered much more quickly. Furthermore, because the device is read sequentially, storage locations belonging to more than one file are read only once, further improving the performance of the content search.

  • Patent number: 8930683
    Abstract: One method of testing multi-threaded code involves accessing a first set of instructions which are configured to be executed, in execution order, as a thread of a multi-threaded process. A memory space is modified, based upon the first set of instructions. The modified memory space represents one or more values that are generated by executing the first set of program instructions in a different order than execution order. The memory space is processed by a second set of program instructions, which is configured to be executed as a second thread of the multi-threaded process.

  • Patent number: 8886605
    Abstract: A method and system for improving performance with single-instance-storage volumes by leveraging data locality is provided. A client provides a set of fingerprints generated from data segments to be saved to a single-instance storage volume and receives the information on whether a data segment exists on the single-instance storage volume and where it is stored if a data segment exists. Based on its received information, the client determines if a number of non-sequential accesses of a computer-readable medium for the said set of segments from the single-instance-storage volume exceeds a predetermined threshold. If so, the client provides the whole set of data segments for storage within the single-instance storage volume regardless of whether or not the data segments are duplicate data segments. These sent data segments will be stored contiguously within the single-instance storage volume while the duplicates will be removed from their previous stored locations.

  • Patent number: 8874907
    Abstract: Providing authentication of users accessing an NFS shared file system. A shared secret is used as a component of the mount point used to access the NFS share. Upon receiving a request to access to the data in the NFS share, the process creates at least one cryptographic value and then creates a path to the mount point which incorporates the cryptographic value. The process then creates the mount point at the path, e.g., /PATH:k1, where k1 is the cryptographic value. Creation of the mount point is preferably performed using NFS protocol semantics, without requiring any changes to the NFS protocol semantics. A second cryptographic value, k2, may be used for unmounting the mount point.
