Abstract: A technique controls movement of a logical unit of storage (LUN) among computerized storage. The technique involves selecting, by processing circuitry, a set of target storage locations of the computerized storage. The technique further involves performing, by the processing circuitry, performance evaluation operations on each target storage location of the selected set of target storage locations. The performance evaluation operations performed on each target storage location electronically assess a performance outcome of moving a production LUN from a source storage location of the computerized storage to that target storage location. The technique further involves moving, by the processing circuitry, the production LUN from the source storage location to a particular target storage location of the selected set of target storage locations based on a set of electronic performance assessments resulting from the performance evaluation operations performed on each target storage location.

Abstract: A technique evaluates moving a logical unit of storage (LUN). The technique involves adding, while a host accesses a production LUN on a source array, a test LUN on a target array. The technique further involves duplicating host input/output (I/O) requests from the host to form a first set of the host I/O requests for processing on the production LUN on the source array and a second set of the host I/O requests for processing simultaneously on the test LUN on the target array. The technique further involves performing, while the first set of the host I/O requests are processed on the production LUN and the second set of the host I/O requests are processed simultaneously on the test LUN, a performance evaluation on the target array to assess a performance outcome of moving the production LUN from the source array to the target array.

Abstract: Embodiments described herein perform cleanup of backup images of a storage system by applying a record of I/O operations recorded while performing anti-malware operations on the storage system. The recording of the I/O operations can be replayed to resolve malware infections in the backup images, snapshots, or replicas of the storage system without requiring a restore-cleanup cycle for each backup image.
