NOC tech told me this:
I am having troubles loading this server. I set up the HDD in the RAID controller however it does not show up when I try to install CentOS. A quick look at SuperMicro's website shows that this board (X7DCL-3) does not support CentOS using the SAS drives.

Anyone have any idea about this? I need 64bit drivers for Centos 5 64bit o/s for this SAS controller.
According to this post, CentOS 5.2 x64 should work, but 5.3 won't. Have them try loading 5.2.
looks like you're going to need a real controller in there. anything based on LSI (IBM/Dell/LSI/HP/etc) is supported with the megaraid driver
