System z

IBM's family of 64-bit mainframes, introduced in 2000 as the zSeries. It includes the z9, z10 and zEnterprise z196, z114, zEC12 and zBC12 models, all of which are robust, mission critical computer systems that generally run under IBM's z/OS or z/VM operating systems.

IBM's z/Architecture was a major upgrade to the previous ESA/390 mainframes. The first z mainframe was the high-end 900 line, followed in 2002 by the zSeries 800, geared to the mid-size customer. Following is a list of "z" models over the years. The enterprise class designation refers to the high-end machines. See z/OS, zEnterprise, z/Architecture, IBM branding and System/390.
