Can you try driver from below location (Download File Format Hard-Drive) [URL]  You can also try installing OS using Dell Lifecycle Controller. You can get more information on this in below location [URL]
I seem to have the opposite as this post -  [URL] Im trying to install Server 2008 R2, and the installer will not find the array. I tried every driver I can find so far, but Server 2008 R2 doesn't see the drives at all.  When I try a Server 2012 disk, its found and installs on the array with no problems. - Has anyone has this issue?
