SonicWALL aggiornamento Stateful High Availability

For SMB and branch office networks that cannot tolerate downtime, this upgrade enables stateful high availability on compatible SonicWALL firewalls. Deploy two identical TZ300 or SOHO series appliances and configure them as an active/passive pair. When the primary unit fails, the secondary takes over automatically, preserving active sessions and minimizing disruption.

Key specifications

• Feature: Stateful High Availability (HA)
• Compatibility: SonicWALL TZ300 Series, SonicWALL SOHO Series
• Redundancy model: Active/Passive failover
• Session preservation: Maintains active network sessions upon failover
• Configuration synchronization: Automatic between primary and secondary
• Failover trigger: Automatic detection of primary failure
• License duration: Perpetual
• Delivery: Electronic Software Delivery (ESD)

Why choose it

Maximize network uptime and ensure business continuity. Stateful failover keeps VPN tunnels, VoIP calls, and other stateful connections alive, reducing data loss and user impact.

Ideal use cases

• Small to medium business networks requiring high availability
• Branch offices with critical connectivity needs
• Disaster recovery and business continuity planning

Good to know

Requires two identical compatible SonicWALL appliances. Active support and firmware subscriptions on both devices are recommended. Management is integrated with SonicOS.
