Abstract
Resource optimization is one of the key drivers for deploying virtualization technology. Regardless of whethertheresourcesarecurrentlyunder-utilizedorover-utilized,itinfluencestheBusiness.Virtualization offers the potential for a reduction in total server hardware and better management of that hardware, but it is not without its own caveats. There are both advantages and disadvantages to using virtualization in any environment,anditiscriticalthatyouunderstandtherealityofwhatvirtualizationcanofferandreconcilethat with your expectations of how it can be used in yourenvironment.For example, you should not assume that applications are suddenly going to require fewer resources just because they are virtualized. On the contrary, the use of virtualization adds overhead, and virtualized applicationsoftenusemoreresourcesthanbefore.Theactualamountofoverheaddependsonanumberof factors including the type of application, which virtualization engine is being used, what kind of hardware is available, and how it will be used. Before implementing virtualization you need to make sure that you have enough storage bandwidth/space, memory, CPU, network bandwidth and other resources to handle the applicationsANDthevirtualizationoverhead.Whenyouexhaustanysingleresourceonaserverthatisused for virtualization, all guest operating systems may be impacted and seen to wait for that single resource. Thus, low CPU or memory utilization alone is not an indication that additional work can be added - youmust verify that all required resources have availablecapacity.
