System and method for providing data redundancy for remote direct memory access storage devices

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to execute a process, the process comprising:

• 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 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 block and each secondary 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.

A system for providing data redundancy, comprising:

• a primary remote direct memory access (RDMA) storage, wherein the primary RDMA storage stores a plurality of primary blocks and a plurality of primary locks, wherein each primary lock is associated with at least one of the plurality of primary blocks;
• at least one secondary RDMA storage, wherein each secondary RDMA storage stores a plurality of secondary blocks and a plurality of secondary locks, wherein each secondary lock is associated with at least one of the plurality of secondary blocks;
• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• receive a write instruction, the write instruction including data to be written to the primary RDMA storage and a primary block address corresponding to a designated primary block of the plurality of primary blocks;
• determine whether the primary lock associated with the designated primary block and at least one secondary lock are obtained, wherein each secondary lock is associated with a secondary block of a distinct secondary RDMA storage of the at least one secondary RDMA storage;
• and
• write the data included in the write instruction to the primary block and each secondary 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.
