Does Deployment Optimizer need a separate server?

We just finished blue-print and came to a conclusion to use SNP Heuristics and Deployment Optimizer. Since we are not using SNP Optimizer, my question is that should we need a separate server?

I did not find any quicksizer document for Deployment Optimizer however, I could see for SNP Optimizer though.

Any help would be appreciated.

Thanks,
