By now I’m sure you’ve heard all the buzz surrounding server virtualization, more specifically “VMware.” Recently it’s become such a common term that you no longer hear – What is Virtualization? After speaking with hundreds of organizations, the most commonly asked questions aren’t whether or not virtualization technology is reliable and secure but more along the lines of – “When is the right time to begin virtualizing our environment?” or “How do we know which servers are good candidates to be virtualized?”

Determining Factors
For some organizations the determining factors which lead to virtualization projects are very clear. For instance, the current datacenter is busting at the seams and moving into a larger facility is not an option. Another common reason is; the datacenter has completely maxed out its power supply and upgrading to a larger UPS would require huge upfront investments with minimal, if any, ROI.

Within other organizations the reasons for virtualization may not be as obvious. For example: An organization continuously rolls out new applications to provide better support for its users. However, because these applications conflict with one another due to different languages, O/S and bandwidth usage they are run independently on separate physical servers. To support research and development, beta testing and full production applications, several new servers will have to be approved in the upcoming budget. Funds originally designated to other projects have to be eliminated. What this company does not realize is that by adding additional underutilized boxes to the existing server farm, it will only increase operational and maintenance costs needed to manage the already inefficient infrastructure. More importantly investing in new hardware may keep organizations from funding other key business areas that are critical to growing the business. Again I ask; where is the ROI?

Server Utilization
Studies show that the average utilization rate for most Windows servers during peak hours is approximately 10-15%. Unfortunately, when you purchase these servers you are paying for 100% of their resources, no matter what; which is why it makes sense to find ways to increase their utilization. Implementing VMware virtual infrastructure allows you to manage multiple virtual machines and applications running simultaneously on heterogeneous operating systems on a reduced number of physical hosts. Average consolidation ratios that you could expect to achieve are in the range of 8:1. Picture this, a datacenter made up of 100 under-utilized servers can realistically be reduced to10-15 physical servers. As an added value many of the left over servers can then be re-purposed to create a disaster recovery site leading to a highly reliable Business Continuity plan.

Efficient and effective Server Consolidation projects are being successfully deployed at a remarkable rate within organizations of all sizes across every industry imaginable. Virtualization has been fully adopted by all Fortune 100 companies and has quickly become standard practice.

What does all of this mean? It’s simple...


Instead, let Freedom Groups show you how to better utilize your current infrastructure while paving the way for future growth. To benefit from the capabilities that virtual infrastructure offers, companies need clear guidance to assess their existing systems and applications, and then to use that knowledge to plan, build and manage their virtual infrastructure. Freedom Groups can guide you through a phased approach that will initially focus on low risk workloads to validate the benefits of virtualization and progress to the more mission critical loads running in production. Along with Server Consolidation, additional business areas that can greatly benefit from a virtual infrastructure include Business Continuity and Test and Development.
