## Replicating Data With Hitachi TrueCopy and Universal Replicator Software

During data replication, data from a primary cluster is copied to a backup or secondary cluster. The secondary cluster can be located at a geographically separated site from the primary cluster. This distance depends on the distance support that is available from your data replication product.

Oracle Solaris Cluster Geographic Edition (Geographic Edition) software supports the use of Hitachi TrueCopy and Universal Replicator software for data replication. Before you start replicating data with Hitachi TrueCopy or Universal Replicator software, you must be familiar with the Hitachi TrueCopy and Universal Replicator documentation, have the Hitachi TrueCopy or Universal Replicator product, and have the latest Hitachi TrueCopy or Universal Replicator patches installed on your system. For information about installing the Hitachi TrueCopy or Universal Replicator software, see the Hitachi TrueCopy and Universal Replicator product documentation.
