DataCore offers an enterprise-class high availability solution that is designed to avoid equipment and site outages from interrupting access to critical information flow. The goal is to deliver “zero downtime, zero touch” failover to maximize business continuity. The cost-disruptive software, proven in over 25,000 global deployments, constantly mirrors data at high speeds between geographically separate locations. It keeps active-active copies synchronized even when using different types of storage devices at each end. Local and stretched/metro clusters perceive the independent, mirrored copies as a single set of data, simultaneously reachable from either location over redundant paths.
When problems prevent applications from reaching the data at one location, failover to the mirrored copy occurs instantaneously and automatically without disruption, scripting or manual intervention. Similarly, the built-in automation takes care of resynchronization and failback to normal operations after the original cause of the outage is resolved.
