MetroHA Business Continuity Solutions
A stretch cluster is a software-defined storage (SDS) business continuity solution 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.
NexentaStor MetroHA provides a synchronous storage solution with the ability to store data on two disparate sites utilizing ZFS end-to-end data integrity allowing for the best possible uptime while ensuring data integrity when transferred over the WAN.
