    • Methods and systems for controlling a geographic region of data in cloud computing are described. A method implemented in a computer infrastructure including a combination of hardware and software includes: receiving a request from a local computing device to save data on a network including a plurality of data storage locations in a plurality of different geographic regions; determining a specified geographic region of the plurality of different geographic regions by analyzing at least one of: (i) file attributes associated with the data, and (ii) predefined rules; identifying one of the plurality of data storage locations within the specified geographic region based on the determining step; and routing the data to the identified one of the plurality of data storage locations within the specified geographic region.

    • 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.
    • 一种用于管理网络数据处理系统中数据对象的副本的方法,计算机系统和计算机程序产品。 计算机系统识别存储在存储设备上的数据对象的副本。 计算机系统将存储设备分组。 与组内其他组的中心位置的距离相比,组中的每个存储设备距离存储设备到组的中心位置的距离最小。 计算机系统基于对存储设备的功率的管理从存储设备中选择用于从存储设备中删除的一部分数据对象的副本,使得每组中的剩余存储设备能够处理历史上已经进行的并发请求 用于数据对象的副本。 计算机系统从存储设备中删除数据对象副本的一部分。

    • A disk recovery system and method is provided for recovering data from a redundant array of independent (or inexpensive) disks. The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The computer readable storage medium is operable to: determine input/output (I/O) characteristics of one or more disks in an array; monitor the one or more disks in the array to determine when any of the one or more of the disks have failed in the array; and automatically rebuild the failed disk from a standby pool by nominating a disk in the standby pool based on the I/O characteristics of the one or more failed disks prior to failure.
    • 提供了用于从独立(或廉价)磁盘的冗余阵列中恢复数据的磁盘恢复系统和方法。 该方法在具有计算机可执行代码的计算机基础结构中实现,该计算机可执行代码有形地体现在具有编程指令的计算机可读存储介质上。 计算机可读存储介质可操作以:确定阵列中一个或多个盘的输入/输出(I / O)特性; 监视阵列中的一个或多个磁盘以确定阵列中某个或多个磁盘中的任何一个磁盘何时发生故障; 并通过在故障之前基于一个或多个故障磁盘的I / O特性,在备用池中提名磁盘来自动重建故障磁盘。
