The hot-swap is handled by the driver, as I understand it.  When you
swap a drive, the OS has to be told.  The OS then stops using the drive
and considers it "gone", you pull the old drive out using the sled (which
only provides a convenient mechanism to do this, nothing else special),
throw in the new sled, and then tell the OS "ok, new drive there, do your
thing with it".

I *think* they are supported by the "iop" driver (I2O).  Luke Mewburn
(CC'd) has some experience with them, I believe, and might be able to
answer your questions about them better than I can.
