Also, with the "hot-plug cabling" ... it will not make a difference except for you will need a different cable to go from the drives to the SAS 6/iR than is present for the drives to the H700.
Hello everyone, I have a Dell R410 server and have run into the same problem a couple of other people have on the board but haven't been able to find the answer.  Namely, I currently have a Perc 700 sitting in the x16 slot which I now need for a SAS HBA.  Ideally I'd like to put a storage controller in the dedicated slot, replacing the Perc and freeing up the x16 slot.  At the moment I'm looking for any solution which just allows me to put a drive to boot from into the R410. Ideally I would like hardware raid 1 as a minimum but even that I can do without as I need to get the server functioning.  It looks like you can get a SAS 6/ir card or a Perc 6/i card which fits but I don't want to go ahead an order one as I can't confirm how this works with the hot plug cabling. Thanks,   Chris
