Although most companies are not taking advantage of virtual server expansion and contraction capabilities today, it is possible to "borrow" CPU and/or memory capacity from other servers, which are currently not being "taxed", and then return that same CPU and/or memory capacity back to their original "owners"- in their original state. Imagine servers being spoofed to think they have unlimited CPU and memory capacity and subsequently never go beyond processing/workload thresholds again!Many of you IT professionals may be wondering, if server virtualization is available today, why aren't more IT shops taking advantage of this type of money-saving / resource-sharing solution.

Rationalize and Critique Critique your current server environment. Identify and consolidate processing-compatible applications to single servers, or you can virtualize your existing multi-server environment to share processing attributes from a common pool. Only the second choice will aid you in the reduction of purchasing new servers for every new application. As a result you would increase utilization of your existing servers from a typical 10 - 20% to a more effective and efficient 40 -50%. More importantly, you drastically decrease your "unexpected" outages while turning your one-to-one, limited-growth environment into a completely flexible and scalable solution without throwing out your existing investment.
