Designing Today’s Data Center: Realizing the Full Benefits of Virtualization

The need for greater application availability has forever changed the way today’s modern data centers are operating. Businesses of all sizes are on the hunt for solutions that will keep their networks scalable while ensuring that the data and applications they need remain available, wherever and whenever they need them.

It’s because of these demands that virtualization technologies [] have quickly become the default platform for today’s data centers. Offering the benefits of increased scalability and reduced infrastructure expenditures, virtualized servers have become an accepted part of the way businesses around the globe remain competitive and improve efficiencies.  In fact, David J. Cappuccio, Research VP at Gartner, recently estimated that “the ratio of virtual to physical servers is now about 11-to-1.”1

What’s alarming is not the sheer rate at which virtualization technology is being adopted – as the benefits of virtualization technology have been well documented.

Instead, what’s alarming is that despite the growing popularity of virtualization, there are a large number of companies that have failed to build their data centers in a way that enables them to fully embrace the benefits. Yesterday’s highly segmented data center networks do not support key virtualization benefits.  As evidence of this, a recent data center survey conducted by Enterasys reported the following results:


  • 11% of respondents reported serious network complexity challenges as a result of virtualization
  • 64% of respondents were reporting some challenges due to virtualization
  • 23% of respondents felt they were fully benefiting from the deployment of virtualization

That’s right – less than a quarter of the survey’s respondents reported that they were fully benefiting from application throughput and end-user experience.  You can assess our complete Data Center Survey to see more results. 

Why is that? The simple truth is that in order to realize the maximum benefits of virtualization, the rest of the data center has to evolve.
