Elements of the Oracle Solaris Cluster Distaster Recovery framework product configuration are:
Oracle Solaris Cluster installation, with attached data storage. Oracle Solaris Cluster Distaster Recovery framework places no additional restrictions on supported cluster configurations beyond those already imposed by the base Oracle Solaris Cluster configuration guidelines.
Internet connections for inter-cluster management communication and default heartbeat between the Oracle Solaris Cluster installations.
Connections for data replication.
Optional connections for custom heartbeats, if required.
Requires at least Java 1.7.
Disaster recovery (DR) orchestration provides the ability to manage multiple Distaster Recovery framework protection groups as a single entity known as a multigroup. This entity enables an administrator to coordinate disaster recovery protection of multiple clusters and multiple services on a per-site basis.
At initial release, this feature has the following configuration limitations:
Maximum number of clusters in a site: 8
Maximum number of protection groups in a multigroup: 10
Maximum number of multigroups in a site: 10
Maximum number of sites in a cluster: 8
Maximum number of controllers in a site: 3
Contact your Oracle support representative to learn whether an increase of any of these limits has become qualified at a later date.
