High-availability firewall pair delivering multi-gigabit threat prevention with 10 GbE ports and Wi-Fi 6 support

Hardware NSa 3800

Option High Availability

  • High Availability pairs two identical units for continuous uptime
  • Multi-gigabit threat prevention scales for mid-size enterprise networks
  • High port density includes 10 GbE interfaces for flexible connectivity
  • 5 GbE ports enable multi-gigabit wireless throughput with Wi-Fi 6 access points
  • Comprehensive security suite covers intrusion prevention, VPN, application control, malware analysis, URL filtering, DNS Security

High Availability Pair for Continuous Operation

The SonicWall NSa 3800 High Availability appliance is sold as a matched unit to build a failover cluster. Two identical devices run SonicOS with one designated primary and the other secondary to maintain an uninterrupted connection. This configuration targets mid-size and distributed enterprises that cannot tolerate downtime on their security perimeter.

Suited for Multi-Gigabit Threat Prevention Needs

Organisations requiring high port density with 10 GbE interfaces and integrated security services such as intrusion prevention, VPN, application control, malware analysis, URL filtering and DNS Security will benefit. Buyers who need only a single standalone firewall or who lack a second identical appliance for the HA pair should consider a different model.

Rack-Mount Deployment

Installation follows standard rack-mount procedures for each appliance and requires a second unit of the exact same model to form the HA cluster. Common issues arise when the secondary unit firmware version differs from the primary or when the HA heartbeat link is not cabled correctly, causing failover to fail.

Questions about this item

What identical SonicWall appliance must I already own to configure the NSa 3800 High Availability 03-SSC-4663 as a secondary unit?

You need a second SonicWall NSa 3800 running SonicOS to pair as the primary unit for High Availability failover.

Can the 10 GbE ports on this NSa 3800 connect directly to my existing 2.5 GbE SonicWave access points?

Yes, the NSa 3800 10 GbE ports support multi-gigabit links and will negotiate 2.5 GbE speeds with SonicWave access points.

How do I verify the High Availability pair is synchronising state correctly after setup?

Check the SonicOS HA status page for a green Synchronised state and confirm the secondary unit shows passive mode with matching firmware.
