    摘要: An apparatus, system, and method are disclosed for determining prefetch data. A start module communicates a start of a target software process to a storage device. A learning module learns data blocks accessed for the target software process. In one embodiment, a prefetch module prefetches the learned data blocks in response to the start of the target software process. An end module communicates the end of the target software process to the storage device. In one embodiment, the prefetch module terminates prefetching data blocks and the learning module terminates learning the data blocks accessed for the target software process in response to the end module's communication of the end of the target software process.

    摘要: In a data processing environment, data is replicated to a remote or secondary storage device in a manner which reduces the adverse performance effects and inefficient bandwidth usage imposed by the conventional one-transaction-at-a-time process. Transactions to be transferred are grouped by a replication manager by selecting transactions having start times earlier than the completion time of a first transaction. Thus, no transaction in a group will be dependent upon any other transaction in the group. Once selected, all transactions in the group may then be transferred to the secondary storage device.

    摘要: Provided are a method, system, and article of manufacture, wherein a controller receives a request from one of a plurality of hosts. The controller determines whether a primary storage control unit coupled to the controller is operational. A response is generated by accessing the primary storage control unit, in response to determining that the primary storage control unit is operational. The response is generated by accessing a secondary storage control unit, in response to determining that the primary storage control unit is not operational, wherein data is replicated synchronously from the primary storage control unit to the secondary storage control unit.

    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 method of transmitting information from a primary storage control unit to a secondary storage control unit in an asynchronous data copying system. The method includes building multiple descriptor blocks for transmission from the primary storage control unit, and encrypting multiple payloads according to one of n encryption methods. In addition, the n encryption methods are associated with the primary storage control unit and n decryption keys relating to the n encryption methods are associated with the secondary storage control unit. An index to the n encryption keys is associated with the multiple descriptor blocks. The method further includes encrypting each of the payloads according to one of the n encryption methods and indicating, in the index associated with a selected descriptor block, which decryption key relates to the encryption method used for any payload associated with a select descriptor block. Upon transmission of a descriptor block from the primary storage control unit to the secondary storage control unit, the index is read and an appropriate decryption key is applied according to a decryption method to decrypt any payload associated with the descriptor block.

    摘要: Disclosed is a storage system architecture. Array controllers are configured with at least 2M ports, where M is an integers greater than two that corresponds to the number of SAS domains or JBOD units in the system. Serial attached SCSI (SAS) domains or JBOD units are configured with at least 2N ports, where N corresponds to the number of array controllers in the system. At least two of each of the 2N ports are directly connected to a corresponding at least two of each of the 2M ports of each of the N array controllers, thereby establishing direct redundant connectivity between each of the N array controllers and each of the M SAS domains or JBOD units.
