These guidelines apply to the requirements for deploying ESM for Fusion to a single node. You might have other components deployed to that node, such as ESM, which have additional requirements. The hardware requirements are based on dedicated resources allocations. In virtual environments, where there is a risk of over-subscription of the physical hardware, ensure that the Fusion system meets these hardware requirements to avoid installation and functionality issues.
If you install ESM for Fusion on the same node as ESM, you should keep some unused resource capacity on the node. For more information, see “Installing ESM for Fusion and ESM on the Same Node” in the Administrator Guide to ArcSight Command Center for ESM.
