摘要： A method is disclosed for reliably updating a data group in a read-before-write data replication environment. The method reliably updates the data group by receiving an updated data group sent from a first storage medium to a second storage medium, comparing the updated data group with a previous data group previously existing on the second storage medium and writing the updated data group to the second storage medium. The read-before-write and differencing method disclosed maintain reliability by storing multiple copies of changes made to the second storage medium during and after the write process.

摘要： A network component useful in tracking write activity by writing logs containing write address information is described. The tracking component may be used in networked systems employing data mirrors to record data block addresses written to a primary storage volume during the time a data mirror is unavailable. The tracking component can be available to any network originating node, and may therefore track write activity on multiple volumes. At the time a data mirror is reconstructed, the log written may be used to construct a list of block addresses pointing to locations on a primary storage volume wherein data differs from a secondary storage volume member of the mirror. The locations maybe copied from the primary to secondary storage volume to reconstruct the data mirror. The performance impact of the tracking component is minimal and a shared network resource is offered that increases fault tolerance in the event of backup device failures.
摘要翻译：描述了通过写入包含写入地址信息的日志来跟踪写入活动的网络组件。跟踪组件可以用于使用数据镜来记录数据镜不可用时写入主存储卷的数据块地址的网络系统。跟踪组件可用于任何网络始发节点，并且因此可以跟踪多个卷上的写入活动。在重建数据镜像时，所写入的日志可以用于构造指向主存储卷上的位置的块地址的列表，其中数据与镜像的辅助存储卷成员不同。这些位置可能从主存储卷复制到副存储卷，以重构数据镜像。跟踪组件的性能影响最小，并提供共享网络资源，从而在备份设备故障的情况下增加容错能力。

摘要： A method for more effectively distributing the I/O workload in a data replication system is disclosed herein. In selected embodiments, such a method may include generating an I/O request and identifying a storage resource group associated with the I/O request. In the event the I/O request is associated with a first storage resource group, the I/O request may be directed to a first storage device and a copy of the I/O request may be mirrored from the first storage device to a second storage device. Alternatively, in the event the I/O request is associated with a second storage resource group, the I/O request may be directed to a second storage device and a copy of the I/O request may be mirrored from the second storage device to the first storage device.

摘要： An apparatus, system, and method are disclosed for rendering multiple segment hypertext script. An identification module identifies a plurality of segments in a hypertext script. Each segment is delimited by at least one tag and includes an instruction for rendering a segment display region that is a portion of a display image described by the hypertext script. A calculation module calculates display coordinates for each segment display region. The display coordinates specify the spatial location and dimensions of the segment display region. A format module formats each segment as an independently displayable formatted segment hypertext script configured to be displayed within the corresponding segment display region. A rendition module renders each formatted segment hypertext script within the corresponding segment display region as a Java object using Java functionality.

摘要： Disclosed is a technique for transferring data using multiple backup components. Responsibility for a portion of data is assigned to a first backup component. When a data update for the portion of data is received at the first backup component from a primary source, the data update is mirrored to a second backup component that is not assigned responsibility for the portion of data.Also disclosed is a technique for processing data updates with a group of backup components. It is determined that a new backup component is active. Near an end of a consistent transactions set formation period, responsibility for one or more portions of data are assigned to each backup component in the group and to the new backup component. During a next consistent transactions set formation period, data updates are processed with each backup component in the group and the new backup component.Moreover, disclosed is a technique for processing data updates with a group of backup components. It is determined that a first backup component in the group is no longer available. Portions of data for which the first backup component had been assigned responsibility are reassigned to each of the other backup components in the group.

摘要： A method for managing extents in a data storage system includes monitoring usage statistics for an extent residing on one or more powered-up storage devices. In the event the extent has not been accessed for specified period of time (as determined from the usage statistics), the method automatically compresses the extent and migrates the extent to an intermediate repository. Once the amount of data in the intermediate repository reaches a specified level, the method migrates the extent from the intermediate repository to one or more normally powered-down storage devices. If I/O is received for the extent while it resides in the normally powered-down storage devices or the intermediate repository, the method automatically migrates the extent from the normally powered-down storage devices or the intermediate repository to the normally powered-up storage devices. A corresponding apparatus and computer program product are also disclosed.
摘要翻译：用于管理数据存储系统中的盘区的方法包括监视驻留在一个或多个加电存储装置上的盘区的使用统计。如果在指定的时间段内（从使用统计信息确定）没有访问该范围，该方法将自动压缩该范围并将范围迁移到中间存储库。一旦中间存储库中的数据量达到指定的级别，该方法会将程序段从中间存储库迁移到一个或多个正常关闭的存储设备。如果在驻留在通常断电的存储设备或中间存储库中的范围内接收到I / O，则该方法自动将从正常关闭的存储设备或中间存储库迁移到通常供电的存储设备。还公开了相应的装置和计算机程序产品。
