Important
The port settings that you assign for the agent must identically match the agent port settings that you
assigned for agents in the VMM server. For more information about assigning ports, see About
Assigning Ports in Virtual Machine Manager.

VMM Use Scenarios
VMM enhances the productivity of IT administrators when planning, deploying, maintaining, and
optimizing the virtual data center. The sections below describe how System Center VMM helps
administrators tackle the challenges of consolidating the physical environment and provisioning virtual
machines.
Server Consolidation
Server consolidation is a priority for most organizations implementing virtual machine technology. By
consolidating their physical servers, organizations realize two significant business benefits: power
savings and increased asset utilization. Organizations can either take a phased-in or all-at-once
approach to consolidation.
Phased-In Consolidation
The phased-in approach is incremental, and thus involves less disruption in terms of technology and
processes. With this approach, customers typically leave their existing application workloads on
physical servers, and only introduce virtualization for new server requests if they deem that the
anticipated workload is appropriate for virtualization. As older hardware is retired or requires significant
software upgrades, the workloads on those physical servers can be converted to virtual machines.
Thus, over time, data center operations become increasingly virtualized.
VMM supports the phased-in approach to consolidation with tools that make it easy to provision new
virtual machines, such as the centralized library of virtual machine building blocks.
Active Server Consolidation
Organizations that need to address power, cooling, and space issues as soon as possible will choose
an active server consolidation strategy. This scenario requires more upfront planning and staff
resources than the phased-in approach because the IT department must analyze physical servers and
