If the timestamps are out of sync and the Idle unit is available, a complete synchronization is pushed to the Idle unit. If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Idle unit. There are two types of synchronization for all configuration settings: incremental and complete. If the firmware configuration becomes corrupted on the Primary SonicWALL, the Backup SonicWALL automatically refreshes the Primary SonicWALL with the last-known-good copy of the configuration preferences. The Backup SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. Besides disabling PortShield, SonicWALL security appliance configuration is performed on only the Primary SonicWALL, with no need to perform any configuration on the Backup SonicWALL. The Primary and Backup SonicWALL devices are currently only capable of performing Active/Idle High Availability or Active/Active UTM – complete Active/Active high availability is not supported at present.įor SonicWALL appliances that support PortShield, High Availability requires that PortShield is disabled on all interfaces of both the Primary and Backup appliances prior to configuring the HA Pair. The failover to the Backup SonicWALL occurs when critical services are affected, physical (or logical) link failure is detected on monitored interfaces, or when the Primary SonicWALL loses power. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWALL. After a failover to the Backup appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. If the Primary device loses connectivity, the Backup SonicWALL transitions to Active mode and assumes the configuration and role of Primary, including the interface IP addresses of the configured interfaces. During normal operation, the Primary SonicWALL is in an Active state and the Backup SonicWALL in an Idle state. High Availability requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Backup SonicWALL. By default, the Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Backup appliances. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability.

Virtual MAC for reduced convergence time after failover – The Virtual MAC address setting allows the HA Pair to share the same MAC address, which dramatically reduces convergence time following a failover.

You do not need to purchase a second set of licenses for the Backup unit in a High Availability Pair.

Cost-effectiveness – High Availability is a cost-effective option for deployments that provide high availability by using redundant SonicWALL security appliances.

Increased network reliability – In a High Availability configuration, the Backup appliance assumes all network responsibilities when the Primary unit fails, ensuring a reliable connection between the protected network and the Internet.

High Availability provides the following benefits: Both appliances must be the same SonicWALL model. To use this feature, you must register the SonicWALL appliances on MySonicWALL as Associated Products. High Availability provides a way to share SonicWALL licenses between two SonicWALL security appliances when one is acting as a high availability system for the other. Two appliances configured in this way are also known as a High Availability Pair (HA Pair). In the event of the failure of the Primary SonicWALL, the Backup SonicWALL takes over to secure a reliable connection between the protected network and the Internet. High Availability allows two identical SonicWALL security appliances running SonicOS Enhanced to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Backup unit.
