What is the maximum number of HA members that can exist in a cluster?

The maximum number of High Availability (HA) members that can exist in a FortiAnalyzer cluster is five, which includes one primary unit and four secondary units. This design allows for a mix of redundancy and load balancing, helping to ensure continuous availability and effective resource utilization.

In a typical HA setup, the primary unit is responsible for managing the cluster and coordinating the activities of the secondary units. The secondary units serve as backups and can take over if the primary unit fails. Having a higher number of secondary units enhances fault tolerance, allowing for more robust system performance and reliability.

The choice reflects Fortinet’s scaling capabilities, enabling users to build more resilient systems that can support larger environments or greater demand. The maximum limit is significant for organizations that require high availability and reliability for their network management and security monitoring functions.
