Reducing the cost of virtualization using Microsoft Hyper-V and System Center

external source: Microsoft Team’s blog:

One of Microsoft’s recent studies was to understand the recurring labor costs in managing and operating Microsoft Hyper-V versus VMware’s competing platforms. The licensing costs of these products are an important consideration for customers, as are the benefits of physical-to-virtual server consolidations. Both items are often discussed to some length in the industry. However, there have not been any significant published research that compared the more important recurring operational costs of managing production virtual servers. This Microsoft study was originally intended to be used internally within Microsoft to feed into our product planning process, but the results were so eye-opening that they have been made public, which you can download here.

Here are some key points:

· The respondents were located in the U.S. and were surveyed by an outside market research firm using a double-blind survey.

· We focused on Hyper-V and ESX/vSphere only.

· Respondents represent organizations having 500 PCs or more.

· The one-time costs were either assumed to be well known (e.g., licensing) or similar enough (e.g., planning, setup) that these costs were out of scope.

· The statistical “confidence interval” is 7.76% with a confidence level of 95%.

Here are a few summary points from the study:

· The IT labor costs varied widely based on the customer’s IT process maturity, but the average costs were $10,357 per guest when hosted on Hyper-V versus $13,629 per guest when hosted on VMware, a 24% savings for Hyper-V versus VMware, and Hyper-V customers at every maturity level showed lower costs

· The average density of Windows Server guests per server was 30% greater for Hyper-V (7.9) than VMware (6.1

· Customers using Microsoft system management products to manage their hosts had 15.6% lower annual IT labor costs ($9,486) per virtual machine than customers using VMware vCenter ($11,238) and 36.7% lower costs than customers using management products from a mix of vendors ($14,988)

So what should you make of these results? First, don’t ignore the cost to operate, manage and support the products you are using or are considering to use. The acquisition costs are usually just a piece of the overall total cost of ownership. Second, be careful when reviewing claims, such as VM guest densities, from vendors. This study used a statistically significant sample size of 154 companies, yet we have seen vendors make bold claims (example, see this whitepaper from VMware) when using a sample size of only 3 companies.

You should also know that Microsoft don’t have all the answers to where the cost savings originate. Microsoft focuses on building products that are well integrated and easy to use, and thus reduce recurring operational costs. .
