This is a most interesting thread. I'm a little be-fuddled, though.
How will ZFS know to select the RAID-Z2 stripes from each FLX380,
because if it stripes the (5+2) from the LUNS within one FLX380, this
will not help if one frame goes irreplaceably out of service.
Let's say the devices are n

I've been saving my +1s for a few weeks now. ;)

No. Each of the RAIDZs that you create can be combined into a single
pool. Data written
