You can find in HCL that MegaRAID SAS 9265-8i SAS RAID , 3ware 9750-8i SAS RAID Controller, ServeRAID 8i, MegaRAID SAS 9240 / 9240-8i / 9240-4i / PERC H310 / 2004 iMR ROMB / 2008 ROMB are already supported, and that should let your Controller be supported too.

Are you using the latest build of DSSv6?
Did you used the Controller BIOS options to deal with the storage or still not?
