Abstract
A method and apparatus for interfacing two ESCON compatible devices over a communication channel that is not dedicated solely to ESCON communication, such as a public communication network or links, for example, a T1 or T3 line. The devices may include a master storage device and a mirroring storage device disposed at remote locations. In one embodiment, the devices communicate using the ESCON protocol. In other embodiments, the devices communicate using modified versions of the ESCON protocol that have a reduced number of handshakes to improve performance.
