"Survey respondents said that energy conservation was the most difficult issue to resolve with their current tools," Avocent's report reads. "Respondents felt that managing the total costs of power was the second-most-difficult task, and many of the respondents noted that their interest and work with virtualization technology were influenced by the hope of ultimate energy savings."
Separately, EMC released at VMworld 2008 the results of a survey of 150 IT business professionals conducted on the company's behalf by the Enterprise Strategy Group. The results show that less than one-fourth of respondents feel confident in maintaining service levels in virtual environments when using existing management tools. The top three concerns for managing VMware environments were application performance monitoring, virtual security management and mapping virtual machines to physical infrastructure, according to EMC.
"As virtualization technologies continue to be deployed in larger and more complex production environments, greater emphasis will be placed on day-to-day management needs of these environments," said Bob Laliberte, an analyst with Enterprise Strategy Group, in a statement. "Specifically the requirement for operations teams to have complete visibility of the virtual infrastructure and how that maps to the physical infrastructure will be critical."
