Abstract: A system and method for improved redundancy in storage devices are disclosed. The method includes receiving a first data block for writing to a storage device; writing the first block to a journal connected with the storage device; associating a first logical address of a group of logical addresses of the journal with a first physical address of the storage; associating the first physical address to an additional second logical address of the storage device, the second logical address not of the group of logical addresses of the journal; and disassociating the first physical address from the first logical address, in response to associating the first physical address with the additional second logical address.

Abstract: A system and method for providing data redundancy. The method includes receiving a write instruction, the write instruction including data to be written to a primary remote direct access (RDMA) storage and a primary block address corresponding to a designated primary block of the primary RDMA storage, wherein the designated primary block is associated with a primary lock stored in the primary RDMA storage; determining whether the primary lock and at least one secondary lock are obtained, wherein each secondary lock is associated with a secondary block of a distinct secondary RDMA storage; and writing the data included in the write instruction to the designated primary data block and each secondary data block associated with the obtained at least one secondary lock, when it is determined that the primary lock and the at least one secondary lock have been obtained.

Abstract: A system and method for comparing mirrored storage devices. The method includes: selecting, from a storage slice of a first storage device and at least a second storage device, corresponding storage blocks that are not trimmed blocks, wherein trimmed blocks are blocks within a storage device marked for erasure; comparing the corresponding storage blocks such that a non-trimmed block of the first storage device is compared to a corresponding non-trimmed block of the second storage device to determine which storage blocks do not match; and performing a recovery operation between the non-trimmed block of the first storage device and a non-matching corresponding first non-trimmed block of the second storage device.
