Another point, Sun may have 66MHz slots but they have a lot of individual
busses serving them - not just one spanned across all like a lot of
Intel-based boards.  Choosing your slots carefully can distribute the demand
for I/O across a lot of individual PCI busses.
 
Your consultant is playing with theory, not experience, in my opinion.

Hi all, 
        I know there were some debates before regarding OS choices for NBU
but I'd like to ask one particular question. This was coming from an
external consultant.

        Background: I am a Unix guys so normally are biased towards
stability/flexibility etc of *nix. But the consultant told us that since
backups are mainly using I/Os, the buses should be an important deciding
factor as well. He went out and found that even the most expensive of Sun
servers tend to have PCI buses with 66MHZ only (most with 33MHZ) and most of
the Intel boxes have 133MHZ PCI buses. He strongly suggested that we pick
Windows for that.

        Your opinions? 

many thanks
