High Availability

High Availability feature allows two identical NSMs to be configured to provide a reliable continuous connection. Two NSMs will be identical only when all the settings under System > Settings and System > Network > Settings are identical. One NSM is configured as the primary, and an identical NSM is configured as the secondary. If the primary NSM fails, the secondary NSM takes over to secure a reliable connection for the protected network. Two NSMs configured in this way are also known as a High Availability pair (HA pair).

Use the System Monitor page to monitor and assess the performance of your NSM implementation.
