Prerequisites

With all Splunk deployments you need to consider the use case and usage expectation of the system when planning your Splunk hardware capacity. Splunk performance and scalability is influenced by data volume, search quantity, search frequency, and search complexity. These factors, the deployment architecture, and hardware used for the deployment, will determine your success with Enterprise Security.

The Splunk App for Enterprise Security performs a large number of real-time and scheduled searches. These searches have an impact on the overall deployment performance.

In preparation for your deployment, you will need to:

1. Understand your use case and usage expectations

2. Identify your search head hardware capacity

3. Identify your indexer hardware requirements and capacity

4. Plan your installation

Be sure that you have gone through these planning steps, and fulfilled these requirements before you install the Splunk App for Enterprise Security 3.0 release.
