Initially Dell R550 Server was purchased without RAID controller

Now we want to add PERC H755 FRONT /H755  adapter to the server and enable hardware RAID

Server has 8 SAS/SATA backplane  and installed with SATA SSD.

Kindly advise which  cable is required to install PERC H755 front  and also H755 adapter  to connect the adapter to the backplane.
