Why Read This Report

According to a recent Forrester survey, the physical to virtual consolidation ratio of server virtualization users varies significantly by company and industry. If your organization has implemented server virtualization but not realized the expected cost savings, you should analyze your ratio of physical to virtual servers. Retail and wholesale outfits have the lowest ratio, consolidating the fewest virtual machines on a physical box. Financial services firms typically spend more on technology and are more aggressive with virtualization and have one of the higher consolidation ratios.
