Gourt Home::Gourt :: IBM System x
The IBM System x computers form a sub-brand of International Business Machines (IBM´s) System brand servers (the other System sub-brands having the names IBM System i, IBM System p, and IBM System z).
Starting out as IBM PC Server, rebranded Netfinity, then 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.
Note: Previously IBM servers based on AMD Opteron CPUs did not share the xSeries brand, neither did x86 based BladeCenter products. Instead they fell directly under the eServer or as of 2005 the "IBM Systems" umbrella.
