[NAME]  "That was true 15 years ago. Today, a SAS backplane/cable and SAS controller are sufficient to use SAS or SATA drives - no interposer is required." T140 does not have a backplane. [NAME]-Chris M  might have more information about the parts as well as the cables etc.  I do not have access to the PPID database.  This server is very old and well past EOL EOS. [URL] [URL] So I disagree entirely. Giving the OP a solution that does not exist is not good for the user. Look at my post with pictures of the drives as well as the controller in the PCI-E slot. The caveots about F6 AHCI Mass storage drivers still applies regardless of the server version 2003 2008 2012 2016 etc. The drivers are not one click water chicken install. They are cabs nested within exe files nested within ISO or ZIP or otherwise.  You must extract down to the file level for the drivers.  Any containers must be formatted and configured via the RAID BIOS before ANY OS can be installed.   [URL] [IMAGE]   [IMAGE]Backplanes are not the same as Blue Caddy's
