Patent ID: 7139826

Claim:
A method of performing an initial copy procedure in a remote copy system, the method comprising: configuring a network path between a first disk subsystem and a second disk subsystem to increase the speed of data transmission across the network path for the initial copy procedure; after the configuring the network path, configuring the remote copy system for a remote copy operation; after the configuring the remote copy system, performing an initial remote copy operation to copy data across the network path from the first disk subsystem to the second disk subsystem, wherein the initial remote copy operation comprises copying of data initially stored in the first disk subsystem to the second disk subsystem; and after the performing the initial remote copy operation, adjusting the network path to reduce the speed of data transmission across the network path, thereby reducing the speed of at least one subsequent remote copy operation between the first disk system and the second disk system, wherein the at least one subsequent remote copy operation comprises copying of data update from the first disk subsystem to the second disk subsystem and wherein configuring the network path comprises increasing a data transfer rate characteristic of the network path.
