The Metro Mirror function supports copy operations between volumes that are separated by
distances up to 300 km. For disaster recovery purposes, Metro Mirror provides the simplest
way to maintain an identical copy on both the primary and secondary volumes. However, as
with all synchronous copies over remote distances, there can be a performance impact to
host applications. This performance impact is related to the distance between primary and
secondary volumes and, depending on application requirements, its use might be limited
based on the distance between sites.
