    Abstract: Modifying storage distribution in a storage system that includes one or more storage devices, including: detecting, for a storage device among the one or more storage devices, that a storage capacity of the storage device is different from a storage capacity of another storage device of the one or more storage devices, and responsive to detecting that the storage capacity for the storage device is different from the storage capacity of the other storage devices of the one or more storage devices, modifying a distribution of shards of data for a data stripe among the one or more storage devices.

    Abstract: A method of providing block-based storage is described. The method comprises: creating a virtual storage system for storing a dataset, the virtual storage system including a virtual drive layer that includes a plurality of virtual drives for storing at least a portion of the dataset as block data; and a block storage backend layer for storing at least the portion of the dataset as block data, the block storage backend layer including one or more block-based storage devices; receiving an I/O operation with respect to the dataset; and based on the received I/O operation, storing, in the block storage backend layer, an update to the dataset.

    Abstract: A system and method for efficiently storing data in a storage system. A data storage subsystem includes multiple data storage locations on multiple storage devices in addition to at least one mapping table. A data storage controller determines whether data to store in the storage subsystem has one or more patterns of data intermingled with non-pattern data within an allocated block. Rather than store the one or more pattern on the storage devices, the controller stores information in a header on the storage devices. The information includes at least an offset for the first instance of a pattern, a pattern length, and an identification of the pattern. The data may be reconstructed for a corresponding read request from the information stored in the header.

    Abstract: Managing storage device evacuation that includes a plurality of storage devices, including: detecting, by the storage system, an occurrence of a storage device evacuation event associated with a source storage device within a write group, wherein the write group is a subset of storage devices storing a data set; responsive to detecting the occurrence of the storage device evacuation event, identifying, by the storage system, a target storage device for receiving data stored on the source storage device; and migrating, by the storage system, the data stored on the source storage device to the target storage device.
