z/OS Metro/Global Mirror
Metro/Global Mirror is an optional function that is available with the z/OS remote
mirror and copy feature and is supported on the DS8000.
The mirroring capability of z/OS Metro/Global Mirror uses z/OS Global Mirror to
mirror data at a production site to a location that is a long distance away. This
function also uses Metro Mirror to mirror data from the same primary devices at the
production site to a location within a metropolitan area. The z/OS Metro/Global
Mirror function enables a 3-site high availability and disaster recovery z/OS solution
for even greater protection from unplanned outages.
