Storage software and products design/architecture from different storage vendors are often incompatible. This incompatibility of the heterogeneous storage makes the remote disaster recovery infeasible, which results in a lot of wasted storage resources and excessive duplication of investment. To solve the problem of incompatibility for remote disaster recovery of heterogeneous storage, this paper proposed a solution. The feasibility of the solution has been testified by the implementation of a practical case. Accordingly, this scheme can reach six disaster levels and meets the requirement of recoverability, reliability and real-time performance indicators.
