Question authority, yes; but, more importantly, question your vendors. This advice is critically important if you’re a Windows shop migrating to VMware ESX or VI3. said Andrew Kutz, former University of Texas systems analyst and now a Burton Group analyst. Kutz offered this advice during a session at last week’s Server Blade Summit in Anaheim.
“Although VMware sales representatives pitch the idea that IT professionals do not need to know Linux to run ESX, this is a fallacy. It would behoove any shop thinking of running VI3 to have a good understanding of ESX’s console operating system (OS), and it is Red Hat Enterprise Linux 3.0.”
Linux users have an advantage in the virtualization market, because they’re probably more familiar with using online mailing lists and forums for tech support, says Kutz. Online resources and the peer support available there will be life savers during virtualization implementations.
“It seems to be the case that the technology has out-paced the vendors’ ability to support it. There have been instances of 5-month long open support tickets that the vendor is never able to solve. Rely on forums, your own wits, but not vendors.”
