<i>&gt; Built on top of Oracle&#x27;s ZFS</i><p>Didn&#x27;t OpenZFS[1] diverge from Oracle ZFS? Initially Oracle didn&#x27;t want to continue their ZFS in the open and there was a split. I didn&#x27;t really follow what happened to that split afterwards. Nexenta is using OpenZFS.<p>[1]: <a href="http:&#x2F;&#x2F;www.open-zfs.org" rel="nofollow">http:&#x2F;&#x2F;www.open-zfs.org</a>
