Set up your environment for Vulnerability Assessment
Set up your central manager and managed units for Vulnerability Assessment.
If you use Vulnerability Assessment (VA), it is recommended that your central manager is in the same data center as the managed units. Managed units that are running VA, access the central manager for definitions and content.
If a central manager is located in a different data center than the managed units, then environmental factors such as network latency, network congestion, and network traffic can impact performance when the centrally-managed definitions are retrieved.
For example, if your central manager and managed units are in different data centers, then you must set up your assessment and datasource definitions in your central manager, and run the assessment in the managed units. This set up might result in a significantly slower performance.
