irtualization is recognized as a key to better utilization of servers, which by exten- sion will lead to more ef cient data centers. Increasingly, however, it s also being seen as the founda- tion on which all other ef ciency endeavors should be built. "Three years ago virtualization was a new technology that was neither as reliable or as effective as it is now, with all of the redundant features it has today," said Dennis Tolliver, enter- prise server channel sales specialist at Hewlett-Packard. Much of the current application and management software is written with virtualization in mind, providing the redundancy and scalability that s needed to spread workloads over larger numbers of servers to achieve higher ef ciencies. Go beyond the traditional idea of ef ciencies and virtualization offers even more. It s driving more inno- vative and cost-effective methods of data recovery, image manage- ment, lifecycle management and even backup, for example. "When we work with agencies on virtualization they certainly start out by looking to traditional elements of ef ciency, such as the power and cooling savings they will make," said Keenan Baker, inside solutions architect, servers and storage, at CDW Government (CDW-G). "But as they go through the implementation they also real- ize it eases a lot of other issues, such as bringing machines on line faster and easier, that also translate into cost savings." It could take some time for this to become part of the mainstream, however. By and large, agencies are turning to virtualization with tra- ditional expectations of power and cooling savings, said Baker. Other bene ts, such as enhanced man- agement capabilities and consoli- dation of management interfaces, don t yet gure into a lot of buying decisions. Agencies need to take a three-to ve-year outlook on what their invest- ments will do for them, Tolliver said. What most organizations mean when they say they are near full virtualization is that they are run- ning virtualization on something like 80 percent of their servers, said David Cappuccio, managing vice president at Gartner responsible for data center research. But if you ask them what the server performance levels are in peak hours, it s only in the mid 20s. "What they should be looking for instead is what those peak perfor- mance levels are, set a target for what they want them to be, and then put enough workload on the servers to hit that target," he said. "Sometimes It could be one or two workloads, other times 40. But the idea is to get the most performance out of the servers during peak hours, and that way they d get the most data center utilization."
