To combat these growth trends, many enterprises are increasingly investigating and investing in virtualization
technology, such as Oracle Virtual Machine, by moving physical servers to virtual ones. The goal of these types of
moves is to consolidate shared hardware while retaining the benefits of isolation that virtual machines provide.
Consolidation in this way enables the enterprise to free up as many servers as possible while maintaining service-level
agreements.
Consolidation Planner enables enterprises to match managed servers with generic physical machines, Oracle
Exadata, or Oracle Virtual Machines they can be consolidated to. By leveraging metric and configuration data
collected from managed targets within Enterprise Manager, Consolidation Planner helps the enterprise to determine
the optimum consolidation scenarios that also reflect business and technical constraints associated with the
consolidation process.
Each consolidation project defined in Consolidation Planner has key concepts that are essential to the project.
These concepts are defined in Table

Description
Source server
An existing server considered for consolidation.
Destination server
An existing or yet-to-be-purchased server that a source server will be consolidated to.
Also thought of as the consolidation target.
