Method for implementing multi-array consistency groups using a write queuing mechanism |
摘要 |
A method includes applying a write Input/Output (I/O) queue interval to a Logical Unit (LU) member of a consistency group (CG). The method also includes marking each write I/O with a timestamp and suspending I/O from the participating storage array to the LU member of the CG upon the participating storage array receiving a snapshot request from a master storage array. The method further includes determining whether the snapshot request timestamp is within the write I/O queue interval of the participating storage array.
