Abstract
A method and system for providing fault tolerance in a networked client/server computing environment by introducing a server computer comprised of a first computer with a first secondary storage controller and a first communications controller and a second computer with a second secondary storage controller and a secondary communications controller. The invention introduces a high speed communications channel that runs between secondary storage controllers and communications controllers in each of the computers, thereby allowing data flow between the communications controllers and enabling the first and second computers to mirror each other or cooperate to form a cluster server. In addition, the communications channel serves as a pathway for secondary storage I/O dataflow, thereby enabling the first and second computers to share secondary storage resources.
