  1. Solaris 10 on dual Xeon 3.2

    Hello,
    i have a server with 2 processors Xeon 3.2GHz dual-core ( 4 cores
    ), but the solaris found only 2 cores. What can is happen ?

    # psrinfo -pv

    Just a guess: are all 4 cores recognised by the BIOS? If the BIOS
    doesn't see them, Solaris can't. Also, which version of SOlaris 10
    are you using?

    These are not dual-core CPUs. They are one of these (according to the stepping):

    http://processorfinder.intel.com/det...px?sSpec=SL8ZP
    http://processorfinder.intel.com/det...px?sSpec=SL7ZE

    They may support HyperThreading - but this has to be enabled in the BIOS.

    Not dual core...

    hyperthreaded...

    big difference.
