Just came across mention that Flash Cache is not supported with the 3210 and 8.1 (footnote 4):

Has anyone heard why that is? This is very concerning as it seems to suggest that 8.0.2 is the end of the road for us if we wish to continue use of our Flash Cache. I'm finding it hard to believe that this is the case on a system that's only been out for a year and in a system in which Flash Cache was strongly encouraged.
