    Abstract: Described embodiments provide systems and methods for operating a storage system. Writeable snapshot replicas of a production site of the storage system are periodically generated during a snapshot interval. The production site includes a production volume, a production memory, and at least one production application. Input/output (I/O) requests of the at least one production application are saved during the snapshot interval. A test environment is initiated with the writeable snapshot, the test environment comprising a test volume, a test memory, and at least one test application. The at least one test application is run in the test environment and the saved I/O requests of the at least one production application are replayed to the at least one test application in the test environment. Output data is provided from the test environment to the writeable snapshot.

    Abstract: An apparatus in one embodiment comprises at least one processing platform including a plurality of processing devices. The processing platform implements compute services for users and further comprises a copy data manager configured to maintain a data version repository. The data version repository stores under the control of the copy data manager a plurality of data versions for each of one or more of the compute services implemented by the processing platform. A code version repository stores a plurality of code versions for each of one or more of the compute services implemented by the processing platform. The code versions stored in the code version repository and the data versions stored in the data version repository collectively provide a two-dimensional test plane. Automated testing the code versions is carried out by an automated code testing system using multiple distinct ones of the data versions selected from the two-dimensional test plane.

    Abstract: A system can determine timeseries telemetry data of resource utilization of respective data centers of a group of data centers maintained by the system. The system can predict respective hardware requests based on future resource utilization based on the timeseries telemetry data, the hardware requests comprising respective hardware requests at respective data centers of the group of data centers. The system can predict respective future times at which the respective hardware requests will occur. The system can determine respective physical location sources of hardware, respective physical location destinations of hardware, and respective amounts of hardware based on the respective hardware requests and the respective future times. The system can store an indication of the respective physical location sources of hardware, respective physical location destinations of hardware, and respective amounts of hardware.

    Abstract: One example method includes scanning a storage device to obtain data and metadata concerning operation of a computing system, analyzing the data and, based on the analyzing, deriving data groups that include some of the data, and deriving data relationships among some of the data, receiving, by an expert system, a query from a user, and the query specifies a sample object for the expert system to investigate, but the query does not indicate purpose of the user in submitting the query, analyzing the query, based on the data groups and data relationships, and based on the analyzing of the query, generating, by the expert system, query results that comprise a set of user-selectable investigation directions that relate to the sample object, and presenting, by the expert system, the set of user-selectable investigation directions to the user.

    Abstract: One example method includes performing delta operations to protect data. A delta queue is provided that allows a replica volume to be rolled forwards and backwards in time. When rolling the replica volume forward, an undo delta is created such that the replica volume can be moved backwards after being moved forward. When rolling the replica volume backwards, a forward delta is created such that the replica volume can be moved forwards after being moved backwards.
