Abstract: A transition tool creates a reversion snapshot of storage objects and data in a copy-free transition method. The storage objects are transitioned from the formats that the source storage system uses to the formats that the destination storage system uses. During this transition, the transition tool can prevent automatic functions of the source and destination storage systems from deleting the reversion snapshots until a request to commit the transition is received. The transition tool can also monitor the amount of storage space available to each of the storage objects. Upon detecting that the amount of storage space is below a threshold, the transition tool can take the storage objects offline so that they are unavailable to client access. In response to receiving a rollback request, the transition tool can perform operations to restore the reversion snapshot of the storage objects and data on the source storage system.

Abstract: A transition tool estimates a cutover time in a copy-free transition of storage objects. The transition tool determines how many storage objects of each type of storage object there are to transition from a source storage system to a destination storage system. The transition tool can measure an operation time for both the source storage system and the destination storage system. The transition tool can estimate an export duration using the source storage system operation time, the number of each type of storage object, and a number of operations for that type of storage object. The transition tool can estimate an import duration using the destination storage system operation time, the number of each type of storage object, and a number of operations for that type of storage object. A total cutover time can then be calculated from the export and import durations.

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.

Abstract translation: 描述了一种用于资源有限的自适应数据传输的方法和系统。 数据存储系统执行操作，其包括使用由存储控制器管理的多个数据流将数据从一组存储卷迁移到另一组存储卷。 在此数据迁移过程中，存储控制器可以测量数据存储系统的性能，例如CPU负载，内存使用量，网络带宽使用情况以及正在使用的数据流总数。 基于测量的性能和调度信息，数据存储系统可以调整专用于数据迁移的并发数据流的数量，以便及时完成迁移过程，而不会对客户端访问和备份操作造成实质性的不当影响。
