Apologies for yet another off-topic thread :)
Since there has been some discussion about not-quite-server grade hardware, I
would like to ask about your experience with SATA controllers that fully
support hotplug. By fully support I mean I can pull a drive, have udev
register it as missing, put it back in - have the device node re-appear in
/dev. To date I am not aware of any consumer grade (i.e. can be found on
newegg) controller/chipset which can actually do this. Does such a card exist?
Thanks
Peter

What about the AOC-SAT2-MV8?
http://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm
It's the least expensive 8 port card I've found.
Have the drivers progressed far enough to support hotswap? It didn't
work last year when I tried it, but I see there have been updates
made.

Everything intel since ich7, as well as, SIIs JMicron, Promises supports
hotplug out of the box in modern linux (generally - most of the
hardware working under ahci driver in your linux).

I just tested it with SUSE 10.3 x64 2.6.22.17-0.1
It worked fine hot plugging a 1TB Seagate drive, both plug and unplug.
So the drivers are now functional.
At under $15 per port for a 8 port card, that certainly is in the
consumer grade price range.
