| In this appendix, we discuss major features of pSeries hardware while running SuSE Linux Enterprise server Version 8 and the IBM AIX Operating System. We present a general feature comparison of some of the major strengths of pSeries hardware currently available at the time of writing. This changes upon further developments and announcements of Linux and AIX on pSeries hardware in the future. Table B-1 shows a matrix of the major features, such as pSeries hardware options, storage options, operating system- related features and High Performance Computing options. Table B-1.
