Abstract
The storage proxy method is used in a storage area network (SAN) which includes a server, a SAN device coupled to the server, and a first and a second storage systems coupled to the SAN device and their logic units mirrored with each other to form a combined mirrored logical unit. The storage proxy method includes the following steps. One of the logical units of the storage systems as a proxy logical unit is selected. The mirrored logical unit is simulated as a virtual logical unit in the SAN device, wherein the virtual logical unit has a virtual identity the same as the identity of the selected proxy logical unit. A transparent communication for management functions between the server and the proxy logical unit is provided via the virtual logical unit or a special proxy logical unit.
