摘要： A system and method for providing continuous availability of information that is normally transported via a network is provided. The system and method uses a process that is used with each computer in a system to simulate the functionality of a network interface card wherein upon the unavailability of the network, transmission packets containing a unique header are send by one application in the system through the process, which stores the transmission packets in queue, and upon filling of the queue writes filled queue to a send volume contained on a storage system. The storage system then copies the data to a second volume, which can be read by a second application. The first and second volumes can either be remotely dispersed or local to one another.

摘要： Described are techniques used in detection of a data corruption in a computer system. A host issues a write request that includes a checksum value determined in accordance with data associated with the write request. The write request is received by a data storage system that performs data validation using the checksum. If the data validation succeeds, the write operation proceeds. Otherwise, it is determined that the data is corrupt and a checksum error is returned to the issuing host. The host issues a vendor-defined write request operation that includes the checksum as a data field in the request packet sent to the data storage system. Filter drivers are used in obtaining the checksum and modifying the write request packet to specify a vendor-defined write operation if checksumming is enabled for the write operation.

摘要： A method, computer program product, and computing system for receiving a Mode Select command concerning a logical unit number (LUN) from a first host, wherein the Mode Select command defines control information and host identifier information concerning the first host, and the LUN is currently being controlled by a second host. The Mode Select command is processed to determine if the control information and host identifier information included within the Mode Select command signifies an intent by the first host to seize control of the LUN from the second host. If the control information and host identifier information signifies an intent to seize control of the LUN from the second host, the control information and host identifier information included within the Mode Select command is written to a buffer associated with the LUN, wherein the buffer includes a control field and a globally unique identifier (GUID) field.

摘要： A method, computer program product, and computing system for receiving a Mode Select command concerning a single LUN from each of a plurality of potential hosts. Each Mode Select command defines control information and host identifier information concerning the potential host associated with the Mode Select command. The received Mode Select commands are processed serially and in accordance with the order in which the Mode Select commands were received. The first Mode Select command received is accepted and subsequent Mode Select commands received are rejected, thus defining an accepted Mode Select command and one or more rejected Mode Select commands. The control information and host identifier information included within the accepted Mode Select command are written to a buffer associated with the single LUN. The buffer includes a control field and a GUID field.

摘要： A method for storing data includes writing the data to a temporary storage location and buffering a mirror request to copy the data from the temporary storage location to a mirror. Once all the data is present, the validity of the data is determined. If the data is valid, the mirror request is executed. Otherwise, the mirror request is deleted.

摘要： For a data copying operation, data compression using constant number-of-track-groups and a thinly provisioned target device facilitates incremental updates where the size of the compressed data on the target device changes. Compressed data is written to the same LBA as the beginning of the source device chunk cluster LBA (1:1 mapping of data start). A termination string or other demarking device is used to identify space freed on the target device resulting from compression. During an incremental update only changed chunk clusters are changed, and freed space is changed accordingly if necessary.

摘要： Disk array storage device apparatus for enhancing the performance of an application on a data processing system that operates with a disk array storage device in which the completion of tasks associated with different transactions with one logical storage device are conditions precedent to the completion of other transactions. Specific tasks related to the one logical device are given priority over tasks related to all other logical storage devices. In a specific implementation reconnect tasks are given the highest priority with reconnect tasks from the one logical storage device being given the highest priority. A second category of tasks related to the one logical storage device can be given priority over all other tasks except reconnect tasks. All other tasks are given a priority below that of the first and second task categories.
