Abstract: Systems, methods, and machine-readable media are disclosed for collecting, maintaining, and retrieving use and limit data for connected resources, as well as determining an optimal location for creating a new volume (or volumes) on a storage platform and placing the volume at the determined location. A resource tracker collects resource use and/or limits data and stores it in a database. A volume placement service receives a volume deployment specification having constraints for creating a new volume. The volume placement service retrieves the data from the database. The volume placement service identifies an optimal location for the volume based at least in part on given constraints from the specification and the resource usage data. The system places the requested volume at the determined location.

Abstract: Methods, non-transitory computer readable media, and computing devices that manages deletion of data objects by utilizing cold storage includes identifying unreferenced data objects within a set of identified data objects in a storage device. The identified unreferenced data objects are moved from an active tier portion of the storage device to a cold tier portion of the storage devices. The moved unreferenced data objects in the cold tier portion of the storage device manage based on a lifecycle policy.

Abstract: Methods, non-transitory computer readable media, and computing devices are disclosed that facilitate efficient storage operations using variable length encoded segment maps for deduplicated objects. A key name and elements of a segment list are received with a request to store an object. Each of the elements corresponds to a segment associated with the object and comprises a segment hash. A segment map is generated for the object. The segment map includes a header and entries. Each of the entries includes at least an expanded offset, one of the segment hashes, and a start offset. The segment map is stored in an object store, as associated with the key name, along with segment data included in at least one of the elements.

Abstract: Exemplary embodiments provide various techniques for detecting and correcting corrupted or dangling data object handles. In one example, a method is provided for correcting corrupted data object handles. In this method, a redirector file stored on a first logical data container is accessed. This redirector file includes a forward object handle pointing to a first data object stored on a second logical data container and includes a first checksum of the forward object handle. A second checksum of the forward object handle is determined and a comparison is made between the first and second checksums. If a mismatch is detected, the data objects stored on the second logical data container are scanned to extract backward object handles. A backward object handle can be identified to point back to the redirector file. The forward object handle can then be restored to point to the second data object based on the identification.
