We don't have a 10G network yet, but I'd like to use the 10G cards we have in our 6080's to speed up snapmirror traffic between the arrays.
I have two 6080 clusters in close enough proximity to direct connect them.
Is this possible? Do I need to flip the fiber on one end (for cross-over)?
other than assigning private IP addresses at each end, is there anything else?

got an answer...
I’ve done this before – I didn’t have to flip the connections on the fiber, but you’ll want to double-check the cable to make sure the send side won’t be going into the send port on the other card.
I’d recommend giving a private IP to each port:
If you have more than one port on each system, then you can do a multipath snapmirror:
Also, boost the snapmirror window to the maximum size and enable jumbo frames on both sides:
connection1:vol filer2:vol wsize=14680064 * * * * (max for 10GB link)
connection1:vol filer2:vol wsize=7340032 * * * * (max for 1GB link)
ifconfig e0d mtusize 9000 (for snapmirror interface - on command line to change immediately, modify /etc/rc to make permanent)
We saw dramatic CPU cycle savings when enabling jumbo frames.
