This chapter describes data replication technologies you can use with Oracle Solaris Cluster software. Data replication is defined as copying data from a primary storage device to a backup or secondary device. If the primary device fails, your data is available from the secondary device. Data replication helps assure high availability and disaster tolerance for your cluster.
Oracle Solaris Cluster software supports the following types of data replication:
Between clusters – Use Oracle Solaris Cluster Geographic Edition for disaster recovery
Within a cluster – Use as a replacement for host-based mirroring within a campus cluster
You must understand host-based, application-based, and storage-based data replication before you can select the replication approach that best serves your cluster. For more information about using the Oracle Solaris Cluster Geographic Edition framework to manage your data replication for disaster recovery, see the Oracle Solaris Cluster 4.3 Geographic Edition Overview.
