CentOS - Jul 2011 - 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.

Have you set up the array using the disk setup utility?

that is an Intel ICH10 SATA controller, which is purely JBOD hardware, 
it supports Intel's 'Matrix' fake-raid.

I highly recommend you use it in AHCI mode (thats a BIOS setting) and 
configure raid in linux with mdraid

If you want harwdare raid in a DL180G6, you should have gotten one of 
the optional 'real' raid controllers such as the P410i w 1gb flash 
writeback cache.
