ZFS has not been ported to OpenBSD and it is very unlikely that it will be.
I would say 4GB is a good safe minimum for running ZFS on Solaris or
OpenSolaris. ZFS likes to cache as much as possible. If you want good
filesystem performance *and* enough RAM left to actually do something else
with the box beside cache filesystem data, you need some RAM.
