HPE Shadowbase Solution: Active/Backup Disaster Recovery
In Figure 1, the CMA is configured in an active/passive configuration with two HPE NonStop servers. The CMA updates the active NonStop server, which then utilizes Shadowbase to uni-directionally replicate the database changes to the backup NonStop server, in case the primary system fails and the backup server is needed for a failover.
