A single data center is susceptible to large-scale failures that can bring down your network infrastructure. To mitigate such scenarios, FusionSync enables you to connect branch offices to data centers across geographic boundaries and replicate data between them. In a FusionSync setup, a typical storage area network (SAN) replication does not protect you from data loss in case of a data center failure, nor from network downtime that can affect many branch offices at the same time. FusionSync enables Cores in two geographically dispersed data centers to remain in synchronization and enables the Edges to switch to another Core in case of disaster. FusionSync can prevent data loss and downtime.
