Based on switched fibre, this solution allows a customer to pinpoint and support a critical application and scale up as that application grows or new applications are added. Because this solution is SAN based departmental users will be able to evolve their remote copy capabilities to include the following activities at both the departmental, and enterprise levels. In the event of an outage of the initiating subsystem, the solution provides immediate access to the remote data so that the application can continue to run. If there is a disruption at the initiating site, by rebooting a server at the alternate site, the user can gain access to the data at the target subsystem and restart the application in a fraction of the time previously possible. This solution allows the customer to break the link between the initiating system and target system, continuing to run the initiating system in production mode, while concurrently using the remote copy in other applications.
User can re-establish the link between the sites and resynchronize the data with a single command.
