CIOs and IT Decision Makers need savvy IT infrastructure planning to be cost-effective and satisfy increasing expectations for end-user experience. Guess what—or who doesn’t know this—you betta get yer Server Virtualization on!Server Virtualization Refresher

Go ahead, scratch your head. The legacy infrastructure dear to many IT folks has become more expensive than a properly managed set of virtualized platforms—as predicted by most IT enterprise analysts—and now sitting even stronger in the forefront of large and mid-sized enterprises as the way to go.

What are you waiting for? [We know you’re not waiting]

Here’s a five-point run down that we liked from the IT Solutions Blog at ConRes.

Five Refresher Tips for Server Virtualization

  1. How will your software be licensed in a virtual environment?  When you virtualize your systems, will you need new software licenses?  The answer will vary by software.  Find out in advance where you’ll need new licenses.
  2. What is the best virtualization platform for your business?  Each business has different requirements.  And with the amount of virtualization options on the market, the choices can be dizzying.  Work with a trusted IT advisor to determine the most cost-effective virtualization platform that will get the job done.
  3. Does your virtualization plan mitigate failure risk? Virtualization should reduce system risks.  But a poorly implemented virtualization plan can do just the opposite.  Server virtualization means that one physical machine can act as multiple virtual servers.  But what happens when that single machine goes down?The critical point is often the host server.  Contingency plans need to be in place should the host server fail, and the virtualized platform should be designed so that all your critical elements aren’t on the same host server.  In short, don’t put all your eggs in one basket.
  4. Are you overloading your host servers? Each host server can only realistically accommodate a certain number of guest machines.  While that number used to extend to 20 to 50 or even 100 virtual machines on a host, software and applications have become larger and more complex.  Now, industry experts say that 15 virtual servers per host is the likely maximum number, with most enterprises achieving a 6:1 ratio for data applications such as CRM, ERP, databases and e-mail.  It’s important to be realistic about host server capacity so you don’t overwhelm your systems.
  5. Which servers and applications can be virtualized?  Not every server or application can or should be virtualized.  For example, servers that require special hardware or run resource-intensive applications aren’t good candidates for virtualization.  And some common applications just won’t run in a virtual environment.  With a little forethought, you can figure out which applications and servers can work in a virtual environment. Good candidates for virtualization?  Older servers (to avoid upgrade costs or increases in  maintenance costs), multiprocessor servers dedicated to single-processor applications (enabling you to optimize resources), and infrequently used severs (so you can consolidate resources).
