HP ProLiant ML350p Gen8 - 3,5" SAS Bay

[Suxxess]

We have a HP ProLiant ML350p Gen8  Server ( Tower ) with 2,5" Bay Slot i.

But now we need a 3,5"  hard drive SAS Bay, I allready bought the 2 x 2 TB SAS HP drives but now I need that bay.

Is that the correct one?

And need I something more to connect it to the server? Perhaps a SAS controller Card?
