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： 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。
