I recently had an issue with my LUNs from our storage unit going offline. This
caused the zpool to get numerous errors on the luns. The pool is on-line, and
I did a scrub, but one of the raid sets is
degraded:

You don't even have to do that with the LSI SAS2 cards. They no
longer ship alternate IT-mode firmware for these like they did for the

So, what is the story about 4KB disk sectors? Should such disks be avoided with
ZFS? Or, no problem? Or, need to modify some config file before usage?

Did your x4500 cope with 3TB disks without any modifications? I heard the BIOS
does not support >2TB disks?

You could buy an LSI2008 based JBOD sata card. It has typically 8 sata ports.
LSI2008 works directly on S11E, out of the box. That card gives very good
performance, typically close to 1GB/Sec transfer speed. And when you switch
mobo, just bring the LSI2008 card to the new mobo, and you are set.
