forgot to answer this one :) it is exceedingly more expensive to run 84 pieces of hardware in multiple racks. electricity costs, physical storage space costs, hardware costs, environmental conditioning costs, etc. it is FAR cheaper to run a few hosts running virtuals than to run real hardware. the more hardware you run the more you increase your chances of a hardware failure. although possibly measurable, we have absolutely no noticable difference in efficiency of services between virtuals and real hardware. > The next question then is why don't you have the big server > which is currently split into 84 realservers as just one big > realserver?
