The VMware feature is called VMDirectPath I/O, and information on configuring it can be found at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1010789 Once I […]

How much does your virtual environment cost?

Most companies are implementing some sort of virtualization today, but how much does that virtualed server cost? If you have 300 virtual machines, how much does that test/dev system cost? Or that font-end web server? And more importantly — How much would it cost to move that to a public cloud? The Accelerating the Journey […]
