Custom Built NAS

I am building a NAS / Virtual Server. I have run into an issue with the raid controlers, the chassis supports 24 drives and I cant seem to location a hardware level raid controler that can support this many disks. Is it possible to hardware bridge any controlers so they act as one? If so what are your recomendations? Below is what I have speced thus far. Thanks.
