The system supports high availability clustering on the local site with remote logging (data replication capabilities to the backup site. Data replication can be configured either at database level or at storage level. Data replication can be either synchronous or asynchronous. Synchronous data replication imposes a limit on the distance between the two sites (the limit is imposed by the *performance hit* implied by the synchronization of each write on both sites and depends on both network parameters and required performance levels).
