摘要： Disclosed is a technique for applying changes back to an original copy of data to reduce an amount of data transferred. A first indicator is maintained for each block of data in a first storage to indicate whether the block of data has been updated in the first storage since the block of data was last transferred to a second storage. A second indicator is maintained for each block of data in the second storage to indicate whether the block of data has been updated in the second storage since the block of data in the second storage was overwritten by a corresponding block of data in the first storage. Upon receiving a reverse restore operation, each block of data in the second storage for which a second indicator has been set to indicate that the block of data has been updated is transferred to the first storage and each block of data in the second storage that corresponds to a block of data in the first storage for which a first indicator has been set to indicate that the block of data in the first storage has been updated is transferred to the first storage.

摘要： Disclosed is a technique for reducing an amount of data transferred. A first indicator is maintained for each source block of data to indicate whether the source block of data has been updated in source storage since the source block of data was last transferred to target storage. A second indicator is maintained for each target block of data in target storage to indicate whether the target block of data has been updated in target storage since the target block of data was overwritten by a corresponding source block of data. When transferring data from the source storage to the target storage, each source block of data for which a first indicator has been set to indicate that the source block of data has been updated is transferred and each source block of data that corresponds to a target block of data for which a second indicator has been set to indicate that the target block of data has been updated is transferred.
摘要翻译：公开了一种减少传送数据量的技术。为每个数据源块维护第一个指示符，以指示源数据源是否已经在源存储器中更新，因为源数据块最后传输到目标存储。为目标存储器中的每个目标数据块保持第二指示符，以指示目标数据块是否已经在目标存储器中被更新，因为目标数据块被相应的源数据块覆盖。当将数据从源存储器传送到目标存储器时，传送已经设置了第一指示符的数据的源数据块，以指示源数据块已经被更新，并且每个与目标块对应的源数据块的第二指示符被设置为指示目标数据块已被更新的数据被传送。

Information is maintained in memory on an existing relationship between at least one source volume and at least one target volume, comprising: (i) at least one element, wherein each element represents a range of sequential data units in the volume; (ii) at least one relationship entry, wherein each relationship entry represents one relationship; and (iii) at least one element pointer associating one element with one relationship entry, wherein the data units represented by the element are part of the relationship represented by the relationship entry that the pointer associates with the element. A new relationship between at least one target volume and at least one source volume is added. Further, added is a new relationship entry in the memory representing the new relationship and one new element pointer is added in the memory for each element including data units included in the new relationship to associate the element with the new relationship entry, wherein the data units represented by the element are part of the new relationship.

摘要： Provided are a method, system, and program for managing data. A data request is received to a target track in a relationship, wherein the relationship associates a source track with the target track. A destage request to destage the source track is submitted in response to the data request to the target track, wherein executing the data request to the target track is conditioned on receiving a completion response to the destage request. If the source track is not in cache, then a complete response is returned to the destage request. If the source track was in cache when the relationship was established, then the destage request is added to an Input/Output (I/O) queue for the source track. After the source track is destaged in response to processing the destage request in the I/O queue, the complete response is returned to the destage request.

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.
