Figure 8 High availability example configuration
How this configuration works for high availability
If the production application server or volumes become unavailable, application processing fails
over to the backup application server. The remote volume and remote snapshots become acting
primary, and the backup application server becomes the acting production application server,
accessing data from the acting primary volume.
Figure 9 High availability configuration during failover
Data availability if the primary volume or production application server fails
If either the primary volume or production application server in your production site fails, only that
data written to the volume since the last remote snapshot was created is unavailable until the volume
or production application server is restored.
