Virtualization Improves Productivity of Data Center Staff
One of the least recognized factors of server virtualization ROI is the positive impact that virtualization has on the productivity of data center personnel. In this article, we provide statistics showing that the productivity of data center staff improved significantly from 2006 and 2007, concurrent with an increase in OS virtualization levels. These trends are consistent across Windows, Unix, and Linux platforms. We conclude by summarizing the reasons that data center staff productivity benefits from increasing the level of virtualization.

Storage Virtualization: Early Adopters Achieving Benefits
Storage vendors have been promoting virtualization as the next big step towards improving the ability of data centers to maximize storage resources, gain flexibility, and lower the cost of managing increasing amounts of data. This report assesses the economics of storage virtualization, based on the experiences of early adopters as reported in our most recent annual survey. It provides an explanation of storage virtualization technology to gain insight into its potential benefits, and concludes with recommendations for successful implementation. In brief, we find that most adopters are experiencing positive ROI with relatively low risk, but that potential benefits are not yet being fully realized. (4 pp., 4 figs.)[Executive Summary]
Server Virtualization Rates Overall Are Still Low
Server virtualization has major benefits: savings in hardware costs, reduction in floor space requirements, lower power and cooling requirements, and savings in administrative time associated with deployment of physical servers. However, in spite of these promised benefits, overall virtualization rates are still low in practice.
