IBM Enhanced Remote Mirroring - License ( upgrade license ) - 32-64 remote mirrors

Enhanced Remote Mirroring consists of Global Mirror, Global Copy, and Metro Mirror and is designed to provide the ability to mirror data from one storage system to another over extended distances. It is designed to control synchronization from within the storage system so that it is nearly transparent to the host application servers. Unlike FlashCopy, Enhanced Remote Mirroring is designed to provide continuous updates from the primary logical drive to the secondary. This is designed to provide data availability, and is a key technology for implementing Disaster Recovery and Business Continuity plans.
