摘要： Techniques are described for processing a data operation that writes first data to a data portion currently stored on first physical storage of a first storage tier of a data storage system, including storage tiers each having a different performance ranking relative to other storage tiers. Second physical storage is allocated from one of the storage tiers for storing the first data written to the data portion. This one storage tier is selected independent of the first storage tier. The first data is stored in a cache and destaged from the cache to the second physical storage. A single merged copy of data for the data portion is formed. Based on an activity level of the data portion, a target tier is selected for storing the single merged copy of data for the data portion.

摘要： A method, computer program product, and computing system for receiving an indication of a cold cache event within a storage system. The storage system includes a multi-tiered data array including at least a faster data tier and a slower data tier. A data list that identifies at least a portion of the data included within the faster data tier of the multi-tiered data array is obtained from the multi-tiered data array. At least a portion of the data identified within the data list is requested from the multi-tiered data array, thus defining the requested data. The requested data is received from the multi-tiered data array.

摘要： Described are techniques for caching. At a first point in time, a first set of data portions currently stored in a first cache of a first data storage system is determined. Each data portion of the first set is located on a first device of the first data storage system. Sent to a second data storage system is first information including information identifying a storage location on the first device for each data portion of the first set. The second data storage system includes a second device that is maintained as a mirror of the first device. The storage location for each data portion of the first set is used to identify a second storage location of the second device corresponding to the storage location. The first information is used to populate a second cache of the second data storage system.

摘要： Described are techniques for storing first data to a logical data in accordance with a static policy to service reads using data stored in a first storage area. The logical device has its data stored on a first physical device that is mirrored on a second physical device. Each of the first and second physical devices include a first storage area and a second storage area. The first storage areas provide better performance than the second storage areas. The first data is stored at a first location in one of the first storage areas of one of the physical devices and at a second location in one of the second storage areas at the other of the first and the second physical devices. An operation to read the first data is serviced by accessing the first data stored in the first area of the one physical device.

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 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： 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.
摘要翻译：用于存储数据的方法包括将数据写入临时存储位置并缓冲镜像请求以将数据从临时存储位置复制到镜像。一旦存在所有数据，就确定数据的有效性。如果数据有效，则执行镜像请求。否则，镜像请求被删除。

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.
