NGFW Clustering of PA-7500 Series Firewalls
NGFW Clustering of two PA-7500 Series firewalls provides redundancy in the event of
link failure, card failure, or chassis failure.
Data centers need very high levels of network bandwidth and reliability. NGFW
clustering is a way to provide redundancy to two PA-7500 Series firewalls in an NGFW
cluster in the event of a link failure, card failure, or chassis failure. NGFW
clustering blends the legacy HA active/active and active/passive solutions into a
single high availability solution. The two cluster nodes connect over a single HSCI
connection. The firewalls maintain a dual active data plane with a single active
control plane. Neighboring devices see the NGFW cluster as a single Layer 2 (virtual
wire) or Layer 3 device.
The NGFW cluster solution reduces failover time, increases resiliency, and supports a
multichassis link aggregation group (MC-LAG). The firewalls in the NGFW cluster
increase port availability, require fewer IP addresses, and rely on open
standards.
