I'll avoid stating the obvious if I can help it.
Hitesh, yes, Veritas 9.1 can take advantage of a dual proc system. A test was completed for 9.1, though the software release did not entirely effect the processor-utilization changes expressed in 9.0. A fully documented case studying Veritas in 9.0 can be found in the pdf linked below. Check it out.
Of course, like any dual-proc system, just having 2 procs doesn't mean you'll do things faster. Your other hardware and software setup counts too.
Hope that helped.
