摘要： Provided are a method, system, and program for forming a consistency group of data. A command is received to form a consistency group with respect to data received at a first storage site that is mirrored to a second storage site. A first data structure is provided indicating updates to the first storage site not included in the consistency group that are received after the command and a second data structure is provided indicating updates to the first storage site in the consistency group to be formed. A command is transmitted to cause data copied to the second storage site that is part of the consistency group to be copied to a third storage site. Indication is received when the data in the second storage site that is part of the consistency group is copied to the third storage site.

摘要： Disclosed is a technique for maintaining consistency of data. One or more blocks of data identified by a first structure are copied to form a consistent set of data. While not acknowledging completion of write requests to any blocks of data, a second structure is created, wherein the second structure indicates which blocks of data are modified while the consistent set of data is being formed. Also disclosed is a technique for asynchronous copy. Indicators are updated in a first structure for one or more blocks of data, wherein each indicator in the first structure indicates whether a corresponding block of data was modified since the block of data was last sent to remote storage. While copying the blocks of data identified by the indicators in the first structure as having been modified since the blocks of data were last sent to remote storage, indicators in a second structure are updated for the one or more blocks of data, wherein each indicator in the second structure indicates whether a corresponding block of data was modified while a consistent set of data is being formed.
摘要翻译：公开了一种保持数据一致性的技术。由第一结构标识的一个或多个数据块被复制以形成一致的数据集。在不向任何数据块确认写请求的完成的情况下，创建第二结构，其中第二结构指示在形成一致的数据集时修改数据块。还公开了用于异步复制的技术。指示符以用于一个或多个数据块的第一结构进行更新，其中第一结构中的每个指示符指示是否修改了相应的数据块，因为数据块最后发送到远程存储。由于数据块最后发送到远程存储，将第一结构中由指示符标识的数据块复制为已被修改，因此对于一个或多个数据块更新了第二结构中的指示符，其中每个指示符第二结构指示在形成一致的一组数据时是否修改相应的数据块。

摘要： Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.

摘要： A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.

摘要： A method to initialize information disposed in an information storage and retrieval system comprising a data cache and one or more information storage media comprising a plurality of addresses. The method receives an initialization command, where that initialization command comprises a range of addresses and, optionally, an initialization pattern, where the plurality of addresses includes the range of addresses. The method forms and saves state information, where that state information includes the initialization pattern, and generates and saves a plurality of indicators, where that plurality of indicators includes an indicator for each track comprising the range of addresses. The method sets each of those indicators to a first value thereby indicating special handling, and provides an ending status signal, such that the receiving step, forming step, generating step, setting step, and providing step are performed substantially synchronously.

摘要： Provided are a method, system, and program for managing resources in which a local processor sends remote operation requests to be executed by a remote processor having multiple resources. In the illustrated embodiment, the local processor and the remote processor each have a resource manager, each of which maintains a control set for each resource of the remote processor. Each control set of the remote processor resource manager includes a queue for queuing remote operation requests awaiting execution in connection with the resource associated with the control set. Each control set of the local processor resource manager includes a credit counter which keeps track of permissible outstanding remote operation requests. Each local processor control set credit counter is decremented for each remote operation request for the associated resource sent to the remote processor and is incremented for each acknowledgment received from the remote processor. For each remote processor control set, the remote processor resource manager sends an acknowledgment for each remote operation request initiated in connection with the associated resource. For each local processor control set, the local processor resource manager queues remote operation requests if the control set credit counter falls below a threshold after being initialized in accordance with the capacity of the associated remote processor control set queue.
摘要翻译：提供了一种用于管理资源的方法，系统和程序，其中本地处理器发送由具有多个资源的远程处理器执行的远程操作请求。在所示实施例中，本地处理器和远程处理器各自具有资源管理器，每个资源管理器为远程处理器的每个资源维护一个控制集。远程处理器资源管理器的每个控制集合包括用于排队等待与控制集相关联的资源执行的远程操作请求的队列。本地处理器资源管理器的每个控制组包括信用计数器，其记录允许的未完成的远程操作请求。对于发送到远程处理器的相关资源的每个远程操作请求，每个本地处理器控制集信用计数器递减，并且对于从远程处理器接收的每个确认递增递增。对于每个远程处理器控制集，远程处理器资源管理器发送与相关资源相关联的每个远程操作请求的确认。对于每个本地处理器控制集合，如果在根据相关联的远程处理器控制集队列的容量初始化之后控制集信用计数器下降到阈值以下，则本地处理器资源管理器排队远程操作请求。

摘要： A method is disclosed to manage a data cache. The method provides a data cache comprising a plurality of tracks, where each track comprises one or more segments. The method further maintains a first LRU list comprising one or more first tracks having a low reuse potential, maintains a second LRU list comprising one or more second tracks having a high reuse potential, and sets a target size for the first LRU list. The method then accesses a track, and determines if that accessed track comprises a first track. If the method determines that the accessed track comprises a first track, then the method increases the target size for said first LRU list. Alternatively, if the method determines that the accessed track comprises a second track, then the method decreases the target size for said first LRU list. The method demotes tracks from the first LRU list if its size exceeds the target size; otherwise, the method evicts tracks from the second LRU list.
