WAFL trick is COW, which had been popularised massively by ZFS
- mprovost 6y agoOracle paid NetApp a lot of money to settle the patent infringement lawsuit after buying Sun which "borrowed" a lot of WAFL's ideas for ZFS.
- ChuckMcM 6y agoAs you have observed they have an identical design philosophy. There is a not so funny story there where a person interned at NetApp and then went to work at Sun and re-implemented the patented technology as ZFS.
