    摘要： A method, computer system, and computer program product for managing copies of data objects in a network data processing system. The computer system identifies copies of a data object stored on storage devices. The computer system places the storage devices into groups. Each storage device in a group has a smallest distance from the storage device to a center location for the group as compared to distances to center locations for other groups within the groups. The computer system selects a portion of the copies of the data object for removal from the storage devices based on a management of power for the storage devices such that remaining set of storage devices in each group is capable of handling concurrent requests that have been made historically for the copies of the data object. The computer system removes the portion of the copies of the data object from the storage devices.

    摘要： A method, a system, and a computer program product are provided for reducing message passing for contention detection in distributed SIP server environments. The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to determine that a first site is waiting for a first object locked by a second site. The programming instructions are further operable to determine that a third site is waiting for a second object locked by the first site, and to send a first probe to the second site to determine whether the second site is waiting. A second probe is received and indicates that a site is waiting for an object locked by the first site. The second probe further indicates a deadlock in a distributed server environment to be resolved.

    摘要： Systems and methods for reducing power consumption and power leakage in hybrid storage clusters is provided. More specifically, the systems and methods for reducing power consumption select a particular cache (memory) technology in hybrid storage clusters based on performance requirements and/or other parameters associated with an application (file or process). The method can be implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The program instructions are operable to monitor access patterns of one or more applications in one or more memory technologies in a computing system. The program instructions are also operable to select a memory technology to store the one or more applications based on the access patterns of one or more applications.

    摘要： 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. The programming instructions are operable to determine one or more data storage technologies accessible by a file system. The programming instructions are operable to 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 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.
