    摘要: Logging and storage transactions in a database are directed to a single storage server. A modification of a database record is written only once to a log record on the storage server. Subsequently, the storage server interprets the database log records, and modifies the database storage accordingly. The number of bytes written to storage is potentially reduced by fifty percent as compared to writing the log record and then writing the modified database record to the storage server.

    摘要: Method, device and computer program product for determining a characteristic of an identifiable component. The method includes: receiving identification information representative of an identity of components that belong to a group of components, determining at least one characteristic of an identifiable component in response to the received identification information, and performing at least one characteristic responsive operation. The device includes an identifiable component and a component characteristic determiner. The component characteristic determiner is adapted to receive identification information representative of an identity of components that belong to a group of components and to determine at least one characteristic of the identifiable component in response to a relationship between the received identification information and reference identification information. The device is adapted to perform at least one characteristic responsive information.

    摘要: Methods, apparatus and systems for data storage including initiating a destaging process in a storage system for destaging data from a cache to a mass storage device. Upon inputting a standby command to the storage system to inhibit the destaging of the data in a specified range, the destaging of the data in the specified range from the cache to the mass storage device is inhibited.

    摘要: Disclosed is a technique for maintaining consistency of data. One or more blocks of data identified by a first structure are copied to form a consistent set of data. While not acknowledging completion of write requests to any blocks of data, a second structure is created, wherein the second structure indicates which blocks of data are modified while the consistent set of data is being formed. Also disclosed is a technique for asynchronous copy. Indicators are updated in a first structure for one or more blocks of data, wherein each indicator in the first structure indicates whether a corresponding block of data was modified since the block of data was last sent to remote storage. While copying the blocks of data identified by the indicators in the first structure as having been modified since the blocks of data were last sent to remote storage, indicators in a second structure are updated for the one or more blocks of data, wherein each indicator in the second structure indicates whether a corresponding block of data was modified while a consistent set of data is being formed.

    摘要: A method for storing an information block that includes determining to store a current version of an information block stored in a memory unit. The checking if a current version of the information is already stored in a storage unit. The current version of the information block is sent from the memory unit to the storage unit if the answer is negative. Generating storage unit location information indicative of a location, at the storage unit, of the current version of the information block if the answer is positive.

    摘要: Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.
