For reliability and responsiveness, ELM supports three (3) non-proprietary databases.
The Primary Database stores the most recent event, performance, SNMP and Syslog data.
The Failover Database prevents loss of monitoring and alerting while the Primary is unavailable or under routine maintenance.
The Archive Databases store long term data for the support of compliance mandates and security policies.
In new deployments, ELM Enterprise Manager is configured to use the run-time databases included in the product download. These databases will support most testing, low volume and monitoring/alerting applications.
For high event volume environments, a user supplied Microsoft SQL Server 2008 or later is recommended.
