This HA unit contains identical Gen 8 hardware to the primary NSa 4800, delivering 20 Gbps firewall throughput, 1.38 GB\/s VPN throughput, and 1.63 GB\/s IPS throughput with 140,000 new connections per second across 24 Gigabit Ethernet ports and 8 SFP+ expansion slots in a 1U rack-mount chassis, and activates as the live firewall within seconds if the primary unit fails or loses connectivity.\u003c\/p\u003e\n\u003cp\u003eThe HA unit operates in Active\/Passive mode, continuously synchronizing configuration, session state, and security policy with the primary NSa 4800 so that failover is seamless to connected users and VPN tunnels. This unit requires a separately purchased primary NSa 4800 with an active security subscription; the HA unit inherits the primary's licensed security services during failover without requiring its own subscription.
