摘要： Setting a plurality of table entries in a storage device includes subdividing the table entries into a N tasks, placing each of the N tasks in a memory location disposed within the storage device and accessible by a plurality of internal devices, the plurality of the internal devices accessing the memory location to retrieve at least one of the N tasks, and each of the plurality of the internal devices setting table entries corresponding to at least one of the N tasks retrieved from the memory location. Setting table entries may also include setting logical device table entries to indicate corresponding tracks contain invalid data in connection with operation of remote data transfer between multiple storage devices. At least some of the internal devices may include devices for handling remote data transfer between multiple storage devices. At least some of the internal devices may be disk adapters and host adapters of the storage device. The memory location may correspond to a queue.

摘要： Described are techniques used in dynamically modifying RDF groups. A system call is issued by a host computer system to execute a remote system call on a first data storage system to create, remove, or modify an RDF group between the first data storage system and another data storage system that is remotely connected to the first data storage system in an RDF switched environment. As part of executing the remote system call, data is pushed from the first to the second data storage systems without having an established link between the data storage systems. Each data storage system performs processing to make the necessary modifications in all directors in accordance with the dynamic RDF group. A status indicating success or failure of the remote system call is returned to the host computer system.

摘要： A storage node uses storage descriptors for provisioning, monitoring and reporting. The storage descriptors indicate available storage resource capabilities and storage resource requirements for particular applications or types of applications using a common set of metrics. The storage node scales requirements to approximate a particular deployment scenario and then compares available capabilities and requirements as indicated by the storage descriptors.

摘要： Described are techniques for performing data storage optimizations. A data storage optimizer on a first data storage system connected to a set of other data storage systems receives performance classification information. The first data storage system includes a first set of storage devices of a first performance classification. The set of other data storage systems includes a second set of storage devices of a second performance classification different from the first performance classification. A write operation is received from the host to write first data to a target address of a virtually provisioned device. It is determined that physical storage is not currently allocated for the target address of the virtually provisioned device. A first portion of physical storage is allocated for storing the first data. The first portion of physical storage is included in a storage device of the second set having the second performance classification.

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.
