Abstract: A copy-free transition tool converts storage objects from a source format associated with a source storage system to a destination format associated with a destination storage system. The transition tool exports configuration information associated with the source storage system to the destination storage system and brings the storage objects offline. Once the transition tool determines that the storage devices containing the storage objects are physically connected to the destination storage system, the tool can convert file systems from the source format to the destination format while leaving data and file layout unchanged. The tool can also modify metadata associated with each of the storage objects to conform to the destination format and store the modified metadata with the destination storage system.

Abstract: A method and system for adaptive data transfers with limited resources are described. A data storage system performs operations that include migrating data from one set of storage volumes to another set of storage volumes using a number of data streams managed by a storage controller. During this data migration process, the storage controller can measure performance of the data storage system such as the CPU load, memory usage, network bandwidth usage, and the total number of data streams in use. Based on the measured performance and scheduling information, the data storage system can adjust the number of concurrent data streams dedicated to data migration in order to complete the migration process in a timely fashion without substantial undue impact to client accesses and backup operations.
