Alan if your current storage vendor even potentially has a stake in the proposal I would expect they might be willing to help and have access to tools that would help at little or no cost to you. Before we licensed on our own tools we used to lean on the various storage vendors for this kind of help.
If you want a complete independent source with top notch tools and expertise go to the one many of the storage companies do Intellimagic. http://www.intellimagic.net/en/product.phtml?p=Copy%20Services We license some of their tooling directly now and have had good experience with the tools and the available expertise. Getting this wrong is can be very painful and upset your cost model for a proposal so IMHO it is worthwhile to engage with en expert either allied with your storage vendor of choice or independent.

The DASD hardware is HDS. I suppose that it's not necessary to pinpoint the changes down to the dataset or volume; if I can just get a number of bytes changed per period of time per subsystem, that should do. I've just started to peruse IBM manuals and redbooks but I'm wondering if any of you could point me to helpful tools.
