How to take disk image from Windows server 2003 with raid controller (mirroring)?

I have a simple server machine having 2 HDDs (320 GB) raid! In boot, its showing the raid options in that black screen. But inside CPU, I couldn't see any hardware. As per the notification I am thinking that there is a hardware controlling RAID! But it may be software controlled; I dont know. I have total 21 machines with same hardware and software. Each pc are having database softwares in different partition other than OS(C drive). I want to have a backup of the hard disk so that in case of making a new machine, I can just get the same hardware and make the server ready! Previously I used a bootable cd (bart pe) with ghost 8. I was unable to do that here, during booting, the machine shown blue screen! Now I am finding any software having such a option that I can get the whole Image/OS image like ghost 8 from a bootable device to extrenal usb hard drive. I searched for the features of Norton Ghost 15 and Acronis true image 2010 but I couldn't get enough information to be courageous to boot from those cds! I am confused and suffering lot of troubles. Some of the machines are being un-serviceable due to hardware failure! Please is there anybody who can help me out from this situation?
