Abstract: Various systems and methods are described for configuring a data storage system. In one embodiment, a plurality of actual capacities of a plurality of storage devices of the data storage system are identified and divided into a plurality of capacity slices. The plurality of capacity slices are combined into a plurality of chunks of capacity slices, each having a combination of characteristics of the underlying physical storage devices. The chunks of capacity slices are then mapped to a plurality of logical storage devices. A group of the plurality of logical storage devices is then organized into a redundant array of logical storage devices.

Abstract: Methods, non-transitory computer readable media, and computing devices that manages distributed snapshot for low latency storage includes accessing one or more snapshots from one or more solid state devices (SSD), wherein the obtained one or more snapshots are stored in a snapshot allocated capacity of the one or more SSD. A data transfer operation is initiated from a primary storage to a secondary storage using the accessed one or more snapshots. It is determined if the initiated data transfer operation is completed and when it is determined to be completed, the obtained one or more snapshots stored in the snapshot allocated capacity of the one or more SSD are deleted.

Abstract: Examples described herein include a system for storing data. The data storage system stores data in one or more storage locations of a storage drive and generates context information that identifies the data associated with each of the one or more storage locations. The context information is stored in a data buffer, and may include at least one of: an index node, a file block number, or a generation count. Further, the data buffer may be a FIFO circular buffer. The data storage system then uses the context information in the data buffer to verify the data stored in the one or more storage locations during an idle time of the storage drive.
