What are the minimum memory requirements for the FortiSIEM supervisor virtual appliance, when the elastic search database is used?

The correct response regarding the minimum memory requirements for the FortiSIEM supervisor virtual appliance when using the Elasticsearch database is based on the appliance's operational needs and performance standards. The minimum requirement of 32GB RAM is specified to ensure efficient processing, storage, and retrieval of large data volumes typically managed by Elasticsearch.

Elasticsearch relies heavily on memory for indexing, querying, and overall data management efficiency. Having 32GB of RAM allows the appliance to effectively handle multiple concurrent operations, maintain rapid access to data, and support real-time analytics capabilities, all of which are critical for a network security monitoring solution. Adequate memory also helps in optimizing the performance of services and reduces the likelihood of slowdowns or potential bottlenecks caused by insufficient resources.

The other options presented may not meet the performance standards necessary for the FortiSIEM supervisor's effective operation with Elasticsearch, possibly leading to compromised functionality or an inability to process data efficiently.
