Abstract:
1. A method of establishing a communication channel from a storage virtualization controller (SVC) to another SVC, comprising: issuing a message including operation mode of the storage virtualization controller by the storage virtualization controller via a local bus interface used as the communication channel; upon receiving the message of the storage virtualization controller, comparing operation mode thereof to the operation mode of said storage virtualization controller to determine if the communication channel can be established; establishing the communication channel therebetween with a current interface configuration of the local bus if the communication channel can be established; and establishing the communication channel therebetween after at least one of the two storage virtualization controllers changes the operation mode thereof if the communication channel cannot be established, such that the operation modes of the two storage virtualization controllers match with each other, and the communication channel can be established.
