    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： A system is provided for managing data sets in a cloud processing and/or federated environment. In an embodiment, the system described herein may be used in connection with cloud processing of big data sets. The term “big data,” as used herein, may be generally defined to describe data sets so large and complex that they become difficult to work with using on-hand database management tools. The system described herein enables the persistent storage of semantic technology statements for big data sets for processing in a cloud processing and/or federated environment.

    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.
