Turmoil in server wonderlands

The simple answer is - commodity. Commodity is the route to perfect competition, but this will answer the question for low end x86 (Intel specification) based servers. Now what about the differentiation in high end servers where knowledge exists as barrier ? The answer is - nobody cares about this knowledge, here comes the BigData. Purchasing of thousands of desktops, farming them into clusters is 20% of TCO of high end servers, more scale-able and many-many-many more advantages. BigData will make those thousands desktops to ride in parallel delivering computing power and high-availability. The conservatism of enterprises will give 3-5 yeas more for server makers.
