摘要： Methods and apparatus for performing a data migration in a clustered computer system. In one aspect, the availability of the data being migrated is maintained during the migration. In another aspect, a data set is migrated by a transfer utility in one of the hosts in the cluster, and in response to a failure of the host, the migration is resumed without restarting from the beginning point of the data set. In a further embodiment, the hosts in the cluster have agents associated therewith to manage the data migration, and prior to taking at least one action associated with the data migration, the agents coordinate to ensure that the hosts in the cluster are prepared to have the at least one action taken.

摘要： A method and apparatus for managing a migration of a data set from at least one first storage location to at least one second storage location, wherein read requests to the data set from at least one application program executing on a computer system initially are serviced from the at least one first storage location. The data set is copied from the at least one first storage location to the at least one second storage location, and then at least one aspect of the computer system is modified so that read requests to the data set are serviced from the at least one second storage location to achieve the migration. In one embodiment, the migration is subsequently undone by modifying the at least one aspect of the computer system so that read requests to the data set are again serviced from the at least one first storage location. In another embodiment, after the migration is performed, a determination is made as to whether to finalize the migration.

摘要： Methods and apparatus for migrating a logical object. In one embodiment, a migration is performed by automatically determining the source location(s) of the logical object, moving the data stored therein to a target location while maintaining the availability of the data at the source location to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In another embodiment, a migration is performed by automatically provisioning target location(s) to store a logical object, moving the data in the logical object to the target location(s) while maintaining its availability to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In a further embodiment, a migration is performed by moving the data within a logical object from a source logical volume to a target logical volume, automatically servicing access requests from an application program at the target logical volume after moving the data, and retiring the source logical volume.

摘要： One embodiment is directed to a method in a computer system including a host computer and at least one storage system including first and second storage volumes, the host computer including at least one application program executing thereon. The method comprises acts of intercepting and redirecting an access request from the at least one application program to the first storage volume to the second storage volume. Other embodiments are directed to a computer readable medium with instructions for performing the method, a host computer with at least one controller to intercept and redirect the access request. Other aspects are directed to methods in a computer system including a host computer, a first storage system including a first storage volume, and a second storage system including a second storage volume, wherein the second storage volume is a hardware mirror of the first storage volume. One method comprises an act of servicing a read request to the second storage volume while maintaining the second storage volume as an active hardware mirror of the first storage volume. Another method comprises an act of, in response to a failure preventing access from the host computer to the first storage volume, servicing access requests directed to the first storage volume from the second storage volume without reconfiguring the host computer.

摘要： One aspect is directed to a method for performing data migration from a first volume to a second volume while allowing a write operation to be performed on the first volume during the act of migrating. Another aspect is a method and apparatus that stores, in a persistent manner, state information indicating a portion of the first volume successfully copied to the second volume. Another aspect is a method and apparatus for migrating data from a first volume to a second volume, and resuming, after an interruption of the migration, copying data from the first volume to the second volume without starting from the beginning of the data. Another aspect is a method and apparatus for migrating to data from a first to a second volume, receiving an access request directed to the first volume from an application that stores data on the first volume, and redirecting the access request to the second volume without having to reconfigure the application that accesses data on the first volume.

摘要： There is disclosed a method for use in managing databases in data storage systems comprising a plurality of nodes. A request is received to provision storage for a specified application intending to use a database. Based on application-awareness, the storage system is provisioned for storing the database in response to receiving the request. Database tables are distributed across the nodes based on a forecasted first I/O profile between application and database. Information is captured in connection with the activity between the application and database. A second I/O profile is determined based on the captured information. The second I/O profile is an actual in-running I/O profile between application and database. The first I/O profile and second I/O profile are compared. The database tables are re-organized on the nodes based on the comparison identifying a discrepancy between first and second I/O profiles such that storage system is rebalanced.

摘要： Example embodiments of the present invention relate to a method, an apparatus and a computer-program product for man-in-the-middle agent-assisted client filtering. An example method to be performed by the man-in-the-middle includes receiving portions of a data stream transmitted from a source and performing an analysis of the portions of the data stream. Based on the analysis, the man-in-the-middle then may interact with the source. An example method to be performed by an agent at the source includes providing portions of a transmitted data stream to the man-in-the-middle and interacting with the man-in-the-middle.
