Those "multiple HD enclosure" that servers use...some questions

I've seen, but never examined one of these up close. It's tall and skinny and contains 6-10 HD's that are hot-swappable. Does this thing have some kind of mobo inside it? A CPU/controller thingee? I've always been curious as to how you "hook it up" to the main server, and how does it "think" for itself? Thanks for any info.
 
Usually, they're SCSI drives on a standard SCSI chain, but I have seen IDE. The IDE ones probably have a SCSI connection to the main system with some intelligent IDE controller integrated inside.
 
The hot-swappable ones might be SCA, or require from kind of frame that achieves the same goal as SCA (a single connector that has power, SCSI ID, and data). There will be an SCA backplane (or similar) that the drives just slide in to.
