Hi,

I am thinking about adding an external Case with 4 haddrives to my 
server that should not be running 247. In ancient times this was done 
via SCSI and simply worked (turn on, rescan SCSI, mount).

I already have an external drive connected via USB, but I am not able to 
read SMART using this link.
x22# smartctl -a /dev/da0

Can this be done with esata and a port multiplier in the box like this one:
http://raidsonic.de/de/pages/products/external_cases.php?we_objectID=4239

I want to use software Raid via ZFS, so this should be a dumb chassis.
Is anyone using a simliar configuration succesfully? Are port 
multipliers supported by FreeBSD? Do I need any special Sata-controller? 
Can I read SMART information?

Regards,
 Michael!
