Unified Client failover
Each device is associated with a primary DWS. When you are creating an application in DRS, you now have the option to include up to three backup DWS servers. If the primary DWS fails or is offline, the secondary DWS server will support the device, allowing the device to continue functioning for users. If a backup DWS server fails, then the device moves to the next DWS in line until it becomes offline when no DWS is reachable. The device stays on a single backup DWS until the primary DWS server is available again; the device does not move up the list of backup DWS nodes. The device only returns to the primary DWS when it is not in use and may go through a period where the device is locked until the primary DWS takes back control.
Currently this feature is only available for certain Unified Clients, including the Unified Client for HP.
