Other Redundancy and Resiliency Features
To protect the firewall from hardware component failures, our high-end firewalls support several types of hardware component redundancy. This includes: dual, hot swappable power supplies; dual, cold swappable solid state drives (SSDs); and swappable fan trays. For details, please refer to the firewall hardware spec sheets.
Our firewalls also include support features and integrations that enable overall availability in your environment. For example, Policy Based Forwarding (PBF) can be used to support redundant Internet access (e.g., between multiple providers). Integration with Application Delivery Controllers (ADCs) can also increase redundancy capability.
