摘要： Provided are a method, system, and article of manufacture for controlling a first storage system receiving commands from a first and second managers to create a consistency group with a second storage system. Host writes are received at the first storage system, wherein the first storage system includes a first storage system primary site and a first storage system secondary site. The first storage system sends the host writes from the first storage system primary site to the first storage system secondary site. Host write operations are quiesced at the first storage system in response to a first command from a first manager. Host write operations are resumed at the first storage system in response to receiving a second command from the first manager. The first storage system receives a run command with a marker, wherein the marker indicates a cycle number to control the cycles of the first and second storage systems. The first storage system sends the marker from the first storage system primary site to the first storage system secondary site. The first storage system sends the marker to a second manager. The first storage system applies the host writes to the first storage system secondary site. The first storage system sends a first message to the first storage system primary site from the first storage system secondary site after completing the applying of the host writes. The first storage system sends a second message to the first manager indicating whether conformation was received from the first storage system secondary site that the host writes were applied.
摘要翻译：提供了一种用于控制从第一和第二管理器接收命令以与第二存储系统一起创建一致性组的第一存储系统的方法，系统和制品。在第一存储系统处接收主机写入，其中第一存储系统包括第一存储系统主站点和第一存储系统辅助站点。第一个存储系统将主机写入从第一个存储系统主站点发送到第一个存储系统辅助站点。响应于来自第一管理器的第一命令，主机写入操作在第一存储系统处于静止状态。响应于从第一管理器接收到第二命令，在第一存储系统处恢复主机写入操作。第一存储系统接收具有标记的运行命令，其中标记指示用于控制第一和第二存储系统的周期的循环数。第一个存储系统将标记从第一个存储系统主站点发送到第一个存储系统辅助站点。第一个存储系统将标记发送给第二个管理器。第一个存储系统将主机写入应用于第一个存储系统辅助站点。第一存储系统在完成主机写入的应用之后，从第一存储系统辅助站点向第一存储系统主站点发送第一消息。第一存储系统向第一管理器发送第二消息，指示是否从主机写入的第一存储系统辅助站点接收到构造是否被应用。

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。
