[CentOS] Suggest Hardware Raid Controller Card

Hi,

I have HP DL 180 G6 2U Server loaded with CentOS 5.6. Can someone
please suggest any good Hardware Raid Controller Card for the
mentioned Hardware and OS. The reason being this server comes with
Onboard Sata Controller chipset (HP Smart Array B110i Controller).
This server has SATA Harddrive - 4 Nos of 500GB each and the OS
doesnot detect it.
