I have a Sun ZFS storage 7320, as there are many document on internet that in order to keep the ZFS at high performance, it is better to keep the usage below 80%.
In my old post in the Solaris forum https://forums.oracle.com/thread/2550071
Cindy said that starting from Solaris 10 1/13 releases, the capacity can further hit until 90%.
However, my question is, how about the Sun ZFS storage 7320? any patches or firmware need to be patched or updated in order to hit 90% as Solaris 10 1/13 releases?
If yes, which patch or which firmware?
