High Availability Configurations

NSv virtual machines deployed on NSv can be configured as high availability Active/Standby pairs to eliminate a single point of failure and provide higher reliability. Two identical NSv instances are configured so that when the primary fails, the secondary takes over to maintain communications between the Internet and the protected network. These redundant NSv instances could share the same license when registered on MySonicWall as associated products. For details, refer to the technical publications portal.

Additional licensing allows configuration of an Active/Standby pair to handle a Stateful fail-over in which the Standby NSv takes over without having to initialize network connections and VPNs. However, dynamic ARP entries and common virtual MACs are not currently supported. For more details, refer to the technical publications portal.
