For each energy consumption report, the plurality of call stacks may be analyzed to determine a representative call stack of the energy consumption report. The energy consumption reports may be assigned to one or more of a plurality of energy consumption categories based on distances between the representative call stacks of the energy consumption reports and corresponding representative call stacks of the energy consumption categories. A request may be received for energy consumption reports for a particular energy consumption category. Upon receiving the request, providing a representative set of energy consumption reports assigned to the particular energy consumption category.
US10949314B2 Method and apparatus for failure recovery of storage device
Techniques perform failure recovery of a storage device. The techniques involve: determining, based on failure data indicating at least one failed disk, whether the at least one failed disk comprises a system disk associated with an extent pool of the storage device, the extent pool being built based on system disks and user disks; in response to determining that the at least one failed disk comprises a system disk, rebuilding the user data of the system disk to one or more further disks associated with the extent pool; and in response to the system disk being replaced with an updated system disk, restoring the rebuilt user data from the one or more further disks to the updated system disk, an association of the system disk with the extent pool being maintained until the system disk is replaced by the updated system disk.
US10949310B2 Physio-logical logging for in-memory row-oriented database system
Restoring a database image of a secondary database system comprises initializing the database image from a recovery image that includes metadata logs and non-metadata logs, of which at least one metadata log includes an undo log of non-committed data that is applied to the initialized database image. A first pagelist and first indexes are then rebuilt based on first data segments of the database image and the corresponding metadata objects. The database image is then updated by replaying the metadata redo log generated from the undo log, the metadata logs, and the non-metadata logs. Then, a second pagelist and second indexes for the database system are rebuilt based on second data segments of the database image and the corresponding non-metadata objects, while each of the first data segments is statically separated from the second data segments in physical memory space. Related apparatus, systems, techniques and articles are also described.
US10949308B2 Application aware backup of virtual machines
Systems and methods for performing application aware backups and/or generating other application aware secondary copies of virtual machines are described. For example, the systems and methods described herein may access a virtual machine, automatically discover various databases and/or applications (e.g., SQL, Exchange, Sharepoint, Oracle, and so on) running on the virtual machine, and perform data storage operations that generate a backup, or other secondary copy, of the virtual machine, as well as backups, or other secondary copies, of each of the discovered applications.
US10949306B2 System and method of a cloud service provider virtual machine recovery
A method and apparatus of a device that recovers accessibility for an inaccessible virtual machine hosted by a cloud service provider is described. In an exemplary embodiment, the device receives an indication that a recovery disk has been attached to a virtual machine hosted by a cloud service provider, wherein the virtual machine is inaccessible to a client. In addition, the device executes an agent that recovers the accessibility of the virtual machine for the client.
