SonicWall TZ380 High Availability Unit with 3.5 Gbps Firewall Throughput, 5 Gigabit Ethernet, 8 Ports with 2 SFP Slots, and Active/Passive Failover for Gen 8 TZ380 Deployments
The SonicWall TZ380 High Availability Unit (03-SSC-6964) is the dedicated failover companion for the TZ380 desktop firewall, providing active/passive high availability that keeps network security online if the primary appliance fails. This HA unit mirrors the primary TZ380's configuration and session state in real time, delivering automatic failover with the same 3.5 Gbps firewall throughput, 204.80 MB/s VPN throughput, and 256 MB/s IPS throughput across 8 Gigabit Ethernet ports and 2 SFP expansion slots in a 1.81 lb Gen 8 desktop chassis running SonicOS 8.
The HA unit synchronizes firewall policies, VPN tunnels, security service configurations, and active sessions with the primary TZ380, so a hardware failure triggers seamless failover without dropping connections or requiring manual intervention. The 5 Gigabit Ethernet support and SFP fiber connectivity match the primary unit's network interface capabilities, and the 13.77W power consumption keeps the standby appliance running at minimal operating cost. The HA unit requires a separately purchased primary TZ380 with an active security subscription and does not include its own security services license.
Where the SonicWall TZ380 HA Unit Fits
- Business-critical environments that cannot tolerate firewall downtime where the active/passive HA pair provides automatic failover if the primary TZ380 experiences a hardware failure, the real-time session synchronization maintains active VPN tunnels and connections during failover, and the matched 3.5 Gbps throughput ensures no performance degradation when the standby unit takes over
- Compliance-driven deployments requiring redundant security infrastructure where regulatory or contractual uptime requirements mandate redundant firewall hardware, the HA configuration provides documented failover capability for audit and compliance reporting, and the Gen 8 SonicOS 8 platform supports the latest security standards including TLS 1.3 and AES-256 encryption
- Remote or branch offices with limited on-site IT support where automatic failover eliminates the need for manual intervention during a firewall failure, the desktop form factor at 5.1 x 7.5 x 1.4 inches allows both the primary and HA unit to fit on a single shelf, and the 15,000 new connections per second handles full traffic loads when the standby unit activates
What the SonicWall TZ380 HA Unit Delivers
- Active/Passive High Availability: Dedicated failover companion for the TZ380 primary unit. Real-time configuration and session state synchronization. Automatic failover without dropped connections or manual intervention.
- Matched TZ380 Performance: 3.5 Gbps firewall throughput with 204.80 MB/s VPN and 256 MB/s IPS throughput. 8 Gigabit Ethernet ports plus 2 SFP expansion slots. 5 Gigabit Ethernet technology. 15,000 new connections per second.
- Gen 8 Platform: SonicOS 8 with synchronized policy and VPN state. 200 VPN tunnels with AES-256, SHA-384, and TLS 1.3. Full feature parity with the primary TZ380 during failover.
- Compact Desktop Form Factor: 1.81 lb desktop chassis at 5.1 x 7.5 x 1.4 inches. 13.77W power consumption. Requires separately purchased primary TZ380 with active security subscription. WEEE, REACH, and RoHS compliant.
How Does Firewall Failover Work
The TZ380 HA pair operates in an active/passive configuration where the primary unit handles all traffic while the standby unit continuously mirrors its configuration, security policies, and active session state through a dedicated HA link. If the primary unit fails or loses connectivity, the standby unit detects the failure and automatically assumes the primary role, taking over all firewall, VPN, and security inspection functions without requiring administrator intervention or disrupting established connections.
