Method of transmitting data between storage virtualization controllers and storage virtualization controller designed to implement the method

摘要

A method of transmitting data between storage virtualization controllers (SVCs) in a computer system is disclosed, in which there is an inter-controller communication channel (ICC) between the storage virtualization controllers. The method comprises the steps of: a central processing unit (CPU) of one storage virtualization controller (SVC) sending a data transfer request to an interface that establishes the ICC when the CPU needs to transmit information to the other SVC; and transmitting the information to the other SVC after the interface that establishes the ICC receives the data transfer request, and obtains the information.
