dell poweredge - Can I do a Raid 5 with a SAS6i/R?

I have a PowerEdge 2970 server with a:
SAS6i/R Integrated Controller for PowerEdge 2950/2970, x6 Backplane

I just bought 3 hard drives that I plan to use in a RAID Configuration
I believe it's called a Raid 5 Configuration where there's 1 main drive all the stay in Sync.

My question is: Will the SAS6i/R Integrated Controller work?

Or do I need to buy something like: Dell Perc5I PCI-E SAS RAID Kit for PowerEdge 2970
