摘要： Provided are a method, system, and program for maintaining consistency when mirroring data using different copy technologies. Update groups having updates to primary storage locations are formed using a first copy technology. The updates in the update groups are copied to secondary storage locations. Update groups having updates to primary storage locations are formed using a second copy technology, wherein the updates in the update groups are copied to secondary storage locations. Indication is made in a data structure of a time of an update in response to including the update in one of the update groups formed using the first copy technology. Indication is also made in the data structure of a time of the update group formed using the second copy technology.

摘要： Disclosed is a system, method, and article of manufacture for maintaining consistent copies of data between a primary site and a secondary site.One or more backup components receive backup messages from the primary site describing transactions. Transactions received from the primary site at the backup components are referred to as “inbound transactions.” The backup components associate these inbound transactions with an identifier such that all transactions associated with a certain identifier comprise all of the activity on the consistency group for a certain period of time. The backup captain periodically notifies the backup components to pause (i.e., stop receiving inbound transactions temporarily), and once all backup components indicate that they have paused, the backup components are notified to resume receiving transactions and associate the newly received transactions with a new identifier.At the same time, the backup components are sending transactions to the secondary storage devices. Transactions sent from caches at the backup components to the secondary site are referred to as “outbound transactions.” The backup components send all transactions from the current outbound consistent transactions set, temporarily stop sending outbound transactions, and notify the backup captain that they have completed sending the current outbound consistent transactions set. When all backup components have completed sending the current outbound consistent transactions set, the backup captain causes consistent copies to be made at secondary storage and notifies the backup components to send the next outbound consistent transactions set.

摘要： Disclosed are a system, a method, and a computer program product to efficiently create consistent transaction sets to maintain one or more copies of data at different data storage sites. All transactions sent to a primary backup appliance during a consistent transaction set creation interval are formed into a consistent transaction set by efficiently adding new transactions as they are received and removing unnecessary transfers as newer versions arrive. When the creation interval has expired, the complete consistent transaction set is transferred to a secondary backup appliance to be used to update a consistent backup copy of the primary site data. For each consistent transaction set, there will be a tree data structure (a search tree) created that contains the addressing information for all of the blocks of data in the consistent transaction set. The tree data structure used is a modified splay tree, which is a specialization of a binary search tree such that accessed nodes are “percolated” to the top of the tree for faster subsequent access. Secondary data consistency is maintained because the consistent transaction sets are applied whole at the secondary site, and after application, the secondary volumes are exact copies of the primary volumes at the time the consistent transaction set was completed.

摘要： A converter system that allows a host system using a first interface to use a second storage using a second interface. The invention provides a method to allow an ECKD MVS DASD storage using an ESCON interface to be used by an open system using a SCSI-type interface without changes to the ESCON storage or the open storage interfaces. The method also permits the SCSI-type interfaced open system to be physically located greater than 25 meters from the ESCON storage system. The method involves mapping the SCSI-type interface data and commands into parameters used and understood by the ESCON storage. The invention may also be implemented to provide a digital data storage medium containing the method of the invention and a digital apparatus capable of executing the invention.

摘要： Disclosed is a system, method, and article of manufacture for maintaining data integrity. A frequency for creating consistent transactions sets is negotiated. A consistent transactions set creation duration is negotiated. At an interval determined by the frequency, during the consistent transactions set creation duration, processing of a first consistent transactions set is completed, while processing of a second consistent transactions set is delayed until the end of the consistent transactions set creation duration. After the first consistent transactions set have been offloaded to secondary storage, consistent copies of data may be created.
