Intelbuyer: I worked at Fortune 100 companies in their IT departments and at various VARs supplying them. It was common practice to upgrade their mainframes with more CPUs and more powerful CPUs. Perhaps you were in something like a web division or PC technical support where, upgrading was less frequent and more like "toss the old and get new" was the norm. But upgrading is far more prevalent on the high end. For example, when I was at GE, they upgraded their mainframe by converting the processor cards to the new higher performance ones. Yes, they added new faster memory as well, but the I/O processors and backplanes stayed the same. They had already done it in the test environment a year prior where the validations passed with flying colors and were upgrading the main mission critical servers (you know those that when down cost millions of dollars in losses every hour). It was all rigorously planned and executed with only minor glitches. 15% higher CPU performance was the goal and that is what they got. No need to replace millions of dollars of known good hardware and software with possibly faulty replacements. I don't know where you worked, but what Dan3 does for his company is more typical of IT in companies both at the Fortune 100 level and below. Pete

Re: I have never worked anywhere that changed out just the chip, when it is time for new severs, we buy all new servers. Pretty much the same here, with some exceptions (I had one site swap in quad core Barcelonas for dual core Opterons in a load balanced cluster when user volume took a big jump). What helps us is that when we buy additional servers, we can buy the same motherboard, fiber HBAs, Raid controllers, etc. The platform administrator techniques and driver set has few or no changes as the parts move from single to dual to quad to ....
