So, Sun's hardware respects flushes, and thus should not torture zfs. That's good to know. > > For the 7000 series in general you can only attach qualified arrays (for > the 7410 specifically).

I'm considering getting a 7110, configuring it in a mirrored configuration resulting in 1TB, which is not too big these days. It would have been perfect to be able to attach a Sun array to it as expansion when more space is needed. Jumping to a 7210 is needlessly expensive in my case. Thanks for your answers though Thanks and Best Regards
