Is it possible to change a Dell Poweredge 2850 from SCSI to use SATA drives? I'm sure it is, but what are the steps?

    I'm afraid with something like that you're not going to be able to convert it.  The Dell Poweredge does not give you the ability to change the backplane or plug in SCSI to SATA bridges, so you're going to be out of luck.

    SCSI (the old kind) is a Parallel interface, and SAS and SATA are Serial interfaces.  You technically have to convert the interfaces using a SCSI to SATA adapter like this one:

    But because of how the Server is built, you won't be able to get that in.

    I strongly advise against those SCSI to SATA bridges, because no way will your RAID controller handle them properly when you get a bad block.  The error recovery logic can't possibly be correct because the SATA disks don't have the proper mode pages to set up the recovery parameters properly  (I used to write RAID firmware and still write diagnostics).

    Get yourself a decent external enclosure and either a SAS/SATA controller or a low-cost eSATA controller/enclosure combo, depending on how many TB of disk you need.

    The parts don't exist to use sata drives internally, the 2850s where built before SAS so only scsi is supported. The newer models like the 2950 uses SAS drives and are compatible with sata drives
