For those businesses that need to mirror data over long distances, or reduce network costs. MirrorView/A is the right choice. The key to MirrorView/A's ability to reduce bandwidth requirements and minimize data exposure lies in its Delta Set architecture. Based on the innovative design of the industry-leading SRDF /Asynchronous solution for the Symmetrix 1 DMX Series. MirrorView/A Delta Sets are disk-resident collections of writes that have occurred within a Specific period of time.
In addition to providing consistent restartable images at the target site, Delta Sets provide the important benefit of reducing the bandwidth needed between sites-which can be the most prohibitive component of a distance replication solution. Delta Sets do this in two ways. The first is through the concept of locality-of-reference. With traditional asynchronous solutions, every write that comes in must be time-stamped/sequenced and sent to the remote side- every write is treated as a discrete write and must be moved over the commu
