摘要： Preparation of a snapshot for data storage includes receiving a first command to prepare to create a snapshot of a set of data stored on at least one source storage volume in a data storage system. The data storage system is prepared to expedite creation of the snapshot in response to the first command. A second command to create the snapshot is received subsequent to the first command. The snapshot is created, in response to the second command, by copying the set of data onto at least one target storage volume at an event time. The set of data may comprise a consistency group comprising a set of data blocks, and preparing the system to create the snapshot may include reserving resources, throttling an incoming data rate, starting a timer after receiving the first command, and/or copying data from a plurality of storage volumes into a memory cache.

摘要： A method for synchronizing data storage systems is provided. The method comprises designating a relationship between a first data storage system and a second data storage system, such that data stored in the first data storage system is copied to the second data storage system, in response to determining that the data stored in the first data storage system has been modified; receiving a first request to modify data stored in a first data block of a first storage volume in the first data storage system, wherein the data block is modified according to the first request; determining that the first data block has not been successfully synchronized when the modified data stored in the first data block is not copied to the second data storage system; and executing a process to retry synchronization of the first data block until synchronization of the first data block is successful, without suspending the relationship while the process is executed.

摘要： A mechanism is provided for managing operations in a data storage system. A first storage controller monitors operation state information associated with a plurality of operation states stored in a data structure. The first storage controller detects a change in the operation state information. The change in the operation state information is in response to a managing entity updating the operation state information to a first operation state in the plurality of operation states in the data structure. Responsive to detecting the change in the operation state information, the first storage controller identifies a reference to a first operation associated with the first operation state updated by the managing entity. The first operation is one operation in a plurality of operations. The first storage controller performs the first operation associated with the first operation state.

摘要： A method to maintain write operation atomicity where a write operation crosses a data storage medium track boundary. The method supplies a storage controller comprising a host adapter, a processor, and a NVS. The host adapter receives from a host computer a write request and data. The method determines if the write request will cross a data storage medium track boundary. If the write request will cross a data storage medium track boundary, the method indicates to the host adapter that the write request comprises a two-track transfer, and writes the data to the NVS as the data is received. If the host computer fails prior to providing all the data to the storage controller, the method discards the data written to the NVS to ensure write operation atomicity.
摘要翻译：一种在写操作与数据存储介质磁道边界交叉的情况下维持写操作原子性的方法。该方法提供包括主机适配器，处理器和NVS的存储控制器。主机适配器从主机接收写入请求和数据。该方法确定写入请求是否将跨越数据存储介质轨道边界。如果写请求将跨越数据存储介质磁道边界，则该方法向主机适配器指示写请求包括双磁道传输，并且在接收到数据时将数据写入NVS。如果主计算机在将所有数据提供给存储控制器之前失败，该方法将丢弃写入NVS的数据，以确保写操作的原子性。
