Starting out as IBM PC Server, rebranded Netfinity, then eServer xSeries and now System x, these servers are distinguished by being based on off-the-shelf x86 CPUs; IBM positions them as their "low end" or "entry" offering.
FLEX-ES must run on the machine with which it was sold; in the past, this included Compaq Proliant and HP servers, but today this is nearly always an approved IBM xSeries server or a ThinkPad laptop.
During this period, the NUMA technology became the basis for IBM's extended X-Architecture (eXA, which could also stand for enterprise X-Architecture).
