@Fonya: Give Intel some credit for radically scaling back the power of Xeon and Atom cores in servers...and fir being the the first to ship a custom low-power SoC for servers. Atom's there today, ARM not yet really.
Perhaps Intel did define the term microserver, but not the drivers behind it and it's natural existence today. Just look at current cost and power requirements in server infrastructure, the shrinking bang for the buck being realized by purchasing the latest, highest-power server processors for current workloads, and the increasing availability of SOC-based processors with enhanced IO and various heterogeneous compute engines. Intelligent scaling is sorely needed that makes use of these growing and different features, not just brute force as has been the mantra in the past.
There's no question Intel is sdoing everything it can to get into this market as aggressively as possible. I am not sure they will be limited to an eight-core offering though. It seems to me that their product lineup will span as far and wide as they can possibly get it to. They won't be giving up their edge in traditional x86 platforms anytime soon either.
