This is always a tough one, because you have no way to measure the pinging
impact outside of Production.  Can you tell us more about the way the data
will be used?  Is it active-standby or active-active for example?

At a high level, I think your problems are probably going to be the other
way round from what you're thinking, though.  If an application is not
designed for OPS use, the likelihood is more of a performance hit because
of pinging with OPS.  This is one of the things that is reduced with Cache
Fusion, but that doesn't yet handle the write-write scenario.

HTH.
