    摘要： A method for migrating extents between extent pools in a tiered storage architecture maintains a data access profile for an extent over a period of time. Using the data access profile, the method generates an extent profile graph that predicts data access rates for the extent into the future. The slope of the extent profile graph is calculated and used to determine whether the extent will reach a migration threshold within a specified “look-ahead” time. If so, the method calculates a migration window that allows the extent to be migrated prior to reaching the migration threshold. In certain embodiments, the method determines the overall performance impact on the source extent pool and destination extent pool during the migration window. If the overall performance impact is below a designated impact threshold, the method migrates the extent during the migration window.

    摘要： A method, system, and computer program product for coordinating the configuration of local and remote storage subsystems for a local client is provided. A command sender is configured on a local storage subsystem to create remote command objects based on commands received from the local client, and deliver the remote command objects to a remote storage subsystem for execution. A command receiver is configured on the remote storage subsystem, the command receiver service having an interface to receive the remote command objects. A remote connection bucket is configured to manage at least one connection between the local storage subsystem and the remote storage subsystem.

    摘要： Disclosed are a system, a method, and article of manufacture to configure information storage and retrieval systems. A configuration loader receives configuration commands from a configuration loader user interface. Upon receipt of configuration commands, the configuration loader transfers storage controller configurations from information storage and retrieval system configuration sources to target information storage and retrieval systems. Threading technology is used to apply a thread manager for managing threads to accomplish the configuration transfers. Multiple physical and/or logical configurations may be transferred simultaneously using the threading technology.
