摘要： A system for dynamic balancing of writes between multiple storage devices in which Remote Data Facility (RDF) groups may be assigned weights according to a dynamic priority parameter. The dynamic priority parameter provides the ability to control the weight of an asynchronous RDF group compared to that of a synchronous RDF group. Thus, when the same RDF adapter includes a mix of asynchronous RDF groups and synchronous RDF groups, a dynamic balance of the write priorities between the two group types may be obtained.

摘要： Storing recovery data for a data center includes providing synchronous data from the data center to a local destination, providing chunks of data from the local destination to a first remote destination, different from the first remote destination, and providing chunks of data from the data center to a second remote destination. At least some of the destinations may maintain a plurality of maps, where each of the maps associates synchronous data being provided to the local destination with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the at least some of the destinations that maintain a plurality of maps may point to a new map. There may be two maps or more than two maps.
摘要翻译：存储用于数据中心的恢复数据包括从数据中心向本地目的地提供同步数据，将来自本地目的地的数据块提供给与第一远程目的地不同的第一远程目的地，以及从数据中心提供数据块到第二个远程目的地。至少一些目的地可以维护多个地图，其中每个地图将提供给本地目的地的同步数据与特定数据块相关联。响应于接收到与创建新的数据块有关的指示符，维护多个地图的至少一些目的地可以指向新的地图。可能有两张地图或两张以上的地图。

摘要： Causing work requests between units of a storage device to be serviced includes scanning an array of data records that contain information indicative of the work requests that have been posted, determining if a particular one of the work requests is not being serviced and reposting the particular one of the work requests if the particular one of the work requests is not being serviced. Reposting the particular one of work requests may include providing the work request directly to a unit that is expected to fulfill the work request. The unit expected to fulfill the work request in connection with the work request being reposted may be different from a unit expected to fulfill the work request when the work request was initially posted or may be the same unit.
摘要翻译：导致要维修的存储设备的单元之间的工作请求包括扫描包含指示已经发布的工作请求的信息的数据记录阵列，确定工作请求中的特定一个是否未被服务并且转发特定的一个的工作请求，如果特定的一个工作请求没有被服务。重新发布工作请求中的特定一个可以包括将工作请求直接提供给期望满足工作请求的单元。预期完成与正在转发的工作请求相关的工作请求的单位可能不同于当初始发布工作请求或可能是同一单位时预期履行工作请求的单位。

摘要： Toggling between a first storage configuration and a second storage configuration includes disabling asynchronous data transfer to a third storage group from one of the first storage group and the second storage group and enabling asynchronous data transfer to the third storage group from an other one of the first storage group and second storage group. Toggling between a first storage configuration and a second storage configuration may also include, prior to disabling asynchronous data transfer to the third storage group, transferring pending data to the third storage group. Toggling between a first storage configuration and a second storage configuration may also include, after enabling asynchronous data transfer to the third storage group, transferring data to the third storage group that had been pending prior to disabling asynchronous data transfer to the third storage group.

摘要： Described are techniques used in dynamically modifying RDF groups. A system call is issued by a host computer system to execute a remote system call on a first data storage system to create, remove, or modify an RDF group between the first data storage system and another data storage system that is remotely connected to the first data storage system in an RDF switched environment. As part of executing the remote system call, data is pushed from the first to the second data storage systems without having an established link between the data storage systems. Each data storage system performs processing to make the necessary modifications in all directors in accordance with the dynamic RDF group. A status indicating success or failure of the remote system call is returned to the host computer system.

摘要： Communicating work requests from a first storage unit of a storage device to a second storage unit of a storage device include providing a data record that contains information indicative of the work request, directly writing the data record from the first unit to the second unit, and writing the data record to a global memory that is accessible by the first unit and by the second unit. Writing the data record to a global memory may include writing the data record to an array in the global memory, where the array may include a plurality of locations that each have space to store a data record. Communicating work requests may also include generating a random number that is used to index the array to determine a location for storing the data record.
