I don’t see this making companies standardize on a single vendor or model. I still assume that companies will buy what ever servers that they can get for the best price.
Just realize that those systems are bought during different times. And with new IT management, they decide on a different vendor platform due to their experience. It’s a merry go around with incoming decision makers to switch vendors midstream. Normally you would want to stick to a single vendor for most part but in certain situation, certain application vendors only certify their products to work on specific hardware.
