Abstract: A method, non-transitory computer readable medium, and device that assists with reducing memory fragmentation in solid state devices includes identifying an allocation area within an address range to write data from a cache. Next, the identified allocation area is determined for including previously stored data. The previously stored data is read from the identified allocation area when it is determined that the identified allocation area comprises previously stored data. Next, both the write data from the cache and the read previously stored data are written back into the identified allocation area sequentially through the address range.

Abstract: The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.

Abstract: Methods and systems for a storage environment are provided. For example, one method includes receiving a request from a storage server at an offload engine for reconstructing data lost due to a failed storage device of a parity group having a plurality of storage devices; retrieving data and parity by the offload engine from the parity group storage devices that are operational; determining by the offload engine XOR of the retrieved data and parity; presenting XOR of data and parity by the offload engine to the storage server with context information associated with the retrieved data; and reconstructing lost data by the storage server using the XOR of data and parity and the context information provided by the offload engine.

Abstract: A method, non-transitory computer readable medium, and storage node computing device that identifies a subset of a plurality of sections of a shelf that is unowned based on a determined ownership status of a plurality of storage devices hosted by the shelf. Obtained section discriminant data is applied to one of a plurality of ordered storage node identifiers to identify one section of the subset of the sections. Ownership of one or more of the storage devices corresponding to the one section is obtained.
