Getting Virtualization Right-
Finally, build a lab using the equipment and workload present in your organization based on organizational surveys conducted by the IT department. Assess the impact of using various virtualization platforms on CPU, RAM, I/O and storage. In particular, if your organization uses multiple virtualization platforms, ensure that you get a management tool that can stretch across these platforms to provide the operational details needed to maintain control of the infrastructure. Baseline the costs of providing virtual infrastructure using the lab to get a starting price that business groups will pay to use the new virtualized environment.
In my story about managing virtualization, I recommend some ways that IT managers can tame existing server sprawl. This sprawl can be avoided altogether at companies just beginning or planning a server virtualization if the following steps are taken.
