What Is EMC MirrorView Software?

EMC MirrorView is a software application that maintains a copy image of a logical unit (LUN) at separate locations. The images are far enough apart to provide for disaster recovery; that is, to let one image continue if a serious accident or natural disaster disables the other.

The production image (the one mirrored) is called the primary image; the copy image is called the secondary image. The primary image is connected to a server called the production host. The secondary image is maintained by a separate storage system that can be a stand-alone storage system or connected to its own server. Both storage systems are managed by the same management station, which can promote the secondary image if the primary becomes inaccessible.
