Thanks for everybody who responded. There were many solutions:

1) Run various scripts
2) sysinfo
3) devinfo -pv

Many people suggested "prsinfo" or "prtconf", however, the SS20 was
running SunOS, not Solaris. Also, the scripts did not produce accurate
value, so I ended up using solution 3 which worked very well.

Thanks to Michael Sullivan for the solution below:
