Notes:

  • The first generation to formally have a "G" designation was the G3 and the last was the G6.
  • P/390, R/390 and 3006 (Integrated Server) are also considered "G2" at a current licensed internal code level
  • Linux for S/390 requires a "G5" or later processor or equivalent in 31-bit mode. Linux for zSeries or System z requires a z/Architecture processor or equivalent in 64-bit mode.
  • z/VM Version 3 requires a "G2" or later processor or equivalent (Architecture Level Set 1). See the z/VM V3.1 General Information Manual, GC24-5944-01 for more information.
  • z/VM Version 4 requires a "G5" or later processor or equivalent (Architecture Level Set 2). See the z/VM V4.4 General Information Manual, GC24-5991-05 for more information.
  • z/VM Version 5 requires a zSeries or System z processor or equivalent (Architecture Level Set 3). See the z/VM V5.4 General Information Manual, GC24-6095-08 for more information.
  • z/VM Version 6 requires a System z10 (or later) processor (Architecture Level Set 4). See the z/VM V6 Reference Guide, ZSO03029-USEN-00 for more information.
  • Information on Processor Version Codes and SRM Constants (including information returned by STIDP and STSI).
