Those who have implemented server virtualization share additional lessons learned
“The biggest lesson is to spread the project out over more time. I don't think I added any risk to my IT operations due to rolling virtualization out in a fresh install method.”
“You can never have enough memory and you can never have enough disk space on the physical machine.”
“I wish I had been more informed as to the variety of options out there. There are numerous options (including open source) that we were just not aware of.”
“Contrary to popular belief, you don't need huge multi-core boxes to run virtualization or a lot of memory or storage. Sure, adding resources by the ton makes performance increase but for most companies, it is not needed. If you plan ahead (just like anything else) there will be few surprises. Every business is different so each system in the end will be different. Just like investing, do your own research.”
“The one thing I wish someone had told me is that just because you are virtualizing things, it doesn't lift you from basic testing. Always reboot your physical host, via reset button or power cord if you can, once the system has all of its services running on it.”
How can small businesses know if virtualization is a fit? To answer this question, CDW surveyed nearly 300 small business Information Technology (IT) professionals through Spiceworks, a social network for IT, interviewing those that have and have not virtualized for their perceptions of and experiences with server virtualization.
The resulting Small Business Virtualization Roadmap examines the opportunities and challenges related to server virtualization.
