What do others do for database file mounts

We are moving to Fibre Channel connections with all of our storage on a Net App storage unit. One of the questions we got from our system admins was if we could limit the number of mounts that they provide us for out datafiles. With the newer disk technology that we all use, is it still important to segregate mounts for redo, CFs, datafiles, Archive logs, etc? I know Oracle stands firm that best practices are to segregate these files into separate mounts. I’m wondering what others do and if there is a compelling reason to continue this practice?

Thanks,
Andy
