Christoph,

You will not find "exact" information, but look in the 7.1 Configuration
Guide.   In Appendix B you will see info about sizing your network.   In
Appendix C you will see hardware recommendations based on previous answer.
You will need to convert it from RS/6000 to SUN specifics.

Kind regards,
