摘要： Provided are a method, system, and article of manufacture for managing writes received to data units that are being transferred to a secondary storage as part of a mirror relationship. Synchronization information indicates data units to transfer from a primary storage to a secondary storage, wherein the synchronization information data is updated to indicate the transfer of one of the data units from the primary storage to the secondary storage. A storage controller receives a write request having an update to a target data unit comprising one of the data units indicated in the synchronization information that has not been transferred from the primary storage to the secondary storage. The write request is allowed to apply the update to the target data unit in response to transferring the data in the target data unit to a network adapter of the storage controller and before the data in the target data unit is transferred to the secondary storage.

摘要： There is provided according to an example of the claimed subject matter, a system and a method for managing access to a shared storage entity. According to an example of the claimed subject matter, a system for managing access to a shared storage entity can include two or more initiator entities, two or more local sequencing agents and an arbitration module. Each of the two or more local sequencing agents can be associated with a respective one of two or more initiator entities which generate I/O requests for accessing the shared storage entity. Each local sequencing agent can be adapted to locally sequence its respective initiator entity's I/O requests. The arbitration module can be adapted to manage an access cycle to the shared storage entity by allocating to each one of the plurality of initiator entities a monolithic/continuous chunk of the access cycle to implement its own I/O access sequence, wherein chunk allocation is determined according to subframe allocation criteria related to the functional characteristics of each of the initiator entities.

摘要： A method for of accelerating database log hardening using specific per block data protection and damage control is provided. A per write specification is implemented to determine when database log data is mirrored synchronously or asynchronously. Synchronous minoring is performed upon reaching a predetermined threshold, based on one or more parameters such as transaction value, both individual and cumulative, and the quantity of data written since the last synchronous minoring. As data is added to the database log, it is written specifying asynchronous minoring to the primary log file. Once a threshold is met, a write specifying synchronous minoring is performed to both the primary and secondary log files, thereby hardening the log file in both primary and secondary storage subsystem.
