There's no such think as Jamaica mirrored drives.  There's a Jamaica
High Availability cabinet.  This cabinet allows the hot-swapping of disc
mechanisms, has a redundant fan, and has a redundant power supply.  The
demo at HPWorld was using a Jamaica cabinet with SOFTWARE disc mirroring
to demo how the cabinet complements software mirroring.  If one mechanism
of a mirrored pair has a failure, the partner disc stays on-line while the
broken disc is removed from the cabinet, repaired, and then replaced in
the cabinet.  Before Jamiaca, you couldn't repair a broken mechanism without
powering down the entire cabinet containing the broken mech.
