zfs

I'm considering to build one with something like this:
http://www.supermicro.com/products/chassis/4U/847/SC847E26-R1400U.cfm
(a chasis with two dual port multipath expanders)
http://www.supermicro.com/products/accessories/addon/AOC-SAS2LP-MV8.cfm
(4 8-port plain SAS controllers, 2 for each backplane)
and 36 Seagate 3Tb SAS drives (ST33000650SS)
OS -- FreeBSD.

And it's very interesting:
How good expander sas backplanes and multipath configurations work with freebsd ?
How to locate a specific drive in the bay? (literally -- how to blink an indicator on the drive in freebsd)
How to detect a fail of a controller?
Will it work together at all?

I'm asking to share any experience.

ZFS replication between 2 ZFS file systems

I initially replicated tank/storage1 -- usb1/storage1-slave (depicted below), and then (deliberately) destroyed the snapshot I replicated from. By doing this, did I lose the ability to incrementally (zfs send -i) replicate between these 2 file systems? What's the best way to approach SYNC'ing these… >>> More
