A Stretch Cluster is a computing cluster configured with host systems located at multiple sites. These may be on different floors of a data center, different buildings on a campus or at multiple metropolitan sites located hundreds of kilometers apart. The high availability and data mobility that stretch clusters provide make them one of the most reliable and flexible solutions that IT administrators can implement to shuttle data between multiple sites. Other benefits of stretch clusters include disaster recovery and downtime avoidance.
