That's a good idea, providing the customer is willing to provide accurate
description of what they want to have modeled. SMF has a lot of really good
averages, but very little in the way of detailed access patterns.
Can you

I say get the vendors to provide the tools and/or analysis to prove their
claims.
They may ask for SMF data from the existing environment to put through their
modeling tools. Make sure they ask for specific SMF record types, as you do
not want to send huge volumes of SMF data to the vendors.

DASD performance tools
PA/IODRIVER http://www.perfassoc.com/
Our shop needs to compare the EMC & IBM DASD performance. Is there any
free tools to test the DASD performance? such as online CICS/Batch
performance?
