High Availability Overview

There are three forms of HA supported by the NSsp 15700:

The NSsp 15700 supports three kinds of High Availability:

• HA Instances with an NSsp 15700— Instances on one NSsp form high availability pairs. See section Instance HA Pair on a Standalone NSsp Node.
• Multi-appliance instance-level HA — Instances on different NSsp 15700 appliances form HA pairs. But not all instances are duplicated on both appliances. See section Configuring Multi-Appliance Instance-Level HA.
• Appliance-level HA — One appliance fully duplicates another instance. This configuration is described in the sections that follow.

Licenses must be in place at both instance and appliance level to support HA.
