The Stealthwatch Data Store provides a central repository to store your network's telemetry, collected by your Stealthwatch Flow Collectors. The Data Store is comprised of a cluster of Data Nodes, each containing a portion of your data, and a backup of a separate Data Node's data. Because all of your data is in one centralized database, as opposed to spread across multiple Flow Collectors, your Stealthwatch Management Console can retrieve query results from the Data Store more quickly than if it queried all of your Flow Collectors separately. The Data Store cluster provides improved fault tolerance, improved query response, and quicker graph and chart population.
In a Stealthwatch deployment with a Data Store, the Data Store cluster sits between your SMC and Flow Collectors. One or more Flow Collectors ingests and deduplicates flows, performs analysis, and reports data and results directly to the Data Store, distributing it roughly equally to all of the Data Nodes. The Data Store facilitates data storage, keeps all of your traffic in that centralized location as opposed to spread across multiple Flow Collectors, and offers greater storage capacity than multiple Flow Collectors.
