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： 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： An apparatus, system, and method are disclosed for determining prefetch data. A start module communicates a start of a target software process to a storage device. A learning module learns data blocks accessed for the target software process. In one embodiment, a prefetch module prefetches the learned data blocks in response to the start of the target software process. An end module communicates the end of the target software process to the storage device. In one embodiment, the prefetch module terminates prefetching data blocks and the learning module terminates learning the data blocks accessed for the target software process in response to the end module's communication of the end of the target software process.

摘要： Disclosed are a system, a method, and a computer program product to provide for the optimization of the output transfer load balance between the peer computers transferring data to one or more storage devices. The peer computers receive, organize and transfer the data to storage devices. The data set is composed of a plurality of data transfers. After an initial division of the data transfers between the two peers, each peer will have assigned responsibility for a number of data transfers. If the one of the peer computers completes offloading transactions earlier than the other peer, then the peer that is still transferring data will employ the other peer to execute a portion of the remaining data transfers. The operation of the system is symmetrical in that either peer may assist the other peer depending upon which peer has idle time. In addition the operation is autonomous and self-adjusting resulting in the peer nodes optimizing the size of the portion of data transfers that are reassigned during the operation of the invention resulting in the minimization of idle time for either peer. The self-adjusting feature allows the system to react to changing conditions that affect data transfer rates to the storage devices.
摘要翻译：公开了一种系统，方法和计算机程序产品，用于提供将数据传送到一个或多个存储设备的对等计算机之间的输出传输负载平衡的优化。对等计算机接收，组织和传输数据到存储设备。数据组由多个数据传输组成。在两个对等体之间的数据传输初始划分之后，每个对等体将分配负责一些数据传输。如果一个对等计算机在其他对等体之前完成卸载事务，那么仍然传输数据的对等体将使用另一个对等体来执行剩余数据传输的一部分。系统的操作是对称的，因为对等体可以根据哪个对等体具有空闲时间来辅助另一对等体。另外，操作是自主的和自调整的，导致对等节点优化在本发明的操作期间重新分配的数据传输部分的大小，从而最小化对等体的空闲时间。自调整功能允许系统对影响存储设备的数据传输速率的变化条件做出反应。
