[Asterisk-Users] Motherboard and processor recommendations

[Paul]

I also agree. You want a raid controller that has it's own CPU. You want 
hot spare, hot swapping, status lights, etc. to be handled by that 
controller. If you have a hot spare you want automatic cutover to that 
spare drive. You are not limited to SCSI with these controllers. Some 
manufactures offer ide and sata versions. If you want hot swap 
capability be sure to do your homework. Some drive hardware advertised 
as hot-swap capable might not work properly with the controller you select.
