This is true at some point but can be dangerous if you neglect it entirely. I have worked as server admin as a part-timer in a company that stalled because they don't use grid technology for their shared plan right from beginning. We have clients complaining the server response and lots of problems with I/O etc. Converting this 500~ shared servers into grid system is painful to do when we have limited time and resources. But, this problem would less occur if we have chosen a slightly expensive but reliable for the long run grid system or the like.
