Abstract
An aspect of performing dual splitting functions in a data replication system include receiving an I/O from a host computer. The host computer includes a first splitter configured to perform control path functions. An aspect also includes adding, via the first splitter, metadata for the I/O to a backlog at the host computer, and sending the I/O to a storage array. The storage array includes a second splitter configured to perform data path functions. An aspect further includes receiving, by the storage array, the I/O from the host computer, and sending, via the second splitter, the I/O to at least one storage device of the storage array and to a data protection appliance (DPA). The control path functions include tracking I/Os and maintaining backlogs including the backlog at the host computer, and the data path functions include mirroring operations in the storage array.
