To configure a
StorageZone for high availability, connect at least two StorageZones
Controllers to it. To do that, you first install a primary StorageZones Controller and
create a zone (as described in
Install StorageZones Controller and create a zone). Then, you install StorageZones Controller on a second server and join that controller to
the same zone.
StorageZones Controllers belonging to the same zone must use the
same file share for storage.
In a high availability deployment the secondary servers are independent, fully functioning StorageZones Controllers. The StorageZones control subsystem
randomly chooses a StorageZones Controller for operations.
If the primary server goes offline, you can easily promote a secondary server to primary. You can also demote a server from primary to secondary.
