Users Hazy on Virtualization ROI, CA Says
Virtualization Virtues Can Be Tough to Quantify So Far

CA had an independent survey done on server virtualization by the Strategic Council and the results suggest that virtualization may not be all it's cracked up to be despite the charge to virtualize.

The Strategic Council says the study shows "a remarkable degree of organizational reluctance to categorize server virtualization deployments as successful."

Seems that 44% of the people they talked who said they had deployed server virtualization couldn't call the deployment a success because they couldn't quantify the ROI; 28% failed to realize an ROI or were unsure that they did; and 40% either failed to realize the documented cost savings or were unsure what cost savings, if any, they did realize.

Of those who figured that they had gotten an ROI 4% achieved it in less than a month, 55% in the first year and 13% more than a year from deployment. And the ROI realized was subject to a great deal of variability: 20% realized an ROI of less than 10%; 61% between 10% and 24%; and 19% an ROI of 25% or more.

The pollsters, who contacted 808 organizations around the world with at least 500 employees, found that 71% of the organizations that have moved ahead with virtualization have deployed, or plan to deploy, multiple server virtualization technologies on the theory that specific solutions are best for specific tasks.

These technologies include operating system and hardware virtualization, operating system partitioning, paravirtualization and/or clustering - actually 60% of the people they talked to consider clustering a form of server virtualization.

This complexity, which indicates uses define virtualization differently than vendors, can impact cost and so ROI.

The primary vendors are VMware, Microsoft and Sun.

CA said the people who felt that virtualization was a success measured it mostly on the basis of performance.

The study found that virtualization is being deployed to improve server/system utilization rates, increase server reliability and uptime and enhance business continuity.

Thirty percent of the respondents were North American, 37% European, 31% in Asia/Pacific and Japan. Sixty-seven percent had between 10 and 99 physical servers and 22% more than 200.
