An apparatus provides coherent data copying operations where data replication is controlled by a source storage controller directly to a destination controller and managed by a remote application. The apparatus generates a snapshot version for each source data block changed by one or more write operations to the source data block during the course of a copy operation; and copies each block of the source data to a corresponding block in the destination data in the absence of the snapshot version of the block and otherwise copying the snapshot version of the source data block to the corresponding block in the destination data.

Coherent device to device data replication

A DataPath Engine coupled to a SAN provides automated storage provisioning between an application on a Storage Area Network (SAN) attached server and a data volume on a SAN attached storage subsystem. The apparatus provides a simple user interface that allows operators to use pre-created policies for criteria to select data paths that meet organizations uptime and performance requirements. The apparatus uses pathing methodologies to select the optimal data path from the candidates by rating SAN state, uptime, performance, and other key factors. This apparatus allows an enterprise to more efficiently and effectively manage and monitor large, complex, distributed SANs.
