I let RH install its own drivers. I will probably then simply reinstall the OS again, this time with linux dd to utilize the Dell PERC drivers. Unfortunately, I was unable to get the PERC firmware to successfully update with Dell's utility.

I've got other methods. I'll try your suggestions when I return to work tomorrow. Thanks!
