Scaling FortiAnalyzer-BigData

You might need to scale the Security Event Manager of FortiAnalyzer-BigData by stacking multiple FortiAnalyzer-BigData appliances to add more storage and query throughput. For example, if you have an existing deployment and want more disk space to store logs for a longer period of time, you can scale out by adding one or more extender chassis. The log data as well as the computing and stateful workload will be distributed across all the hosts in the stacked appliances.
