Support for NFS version 4 has now been enabled on the main NetApp filer "elmer". The change is upwards compatible in the sense that the older protocol remains available as well. However client systems which support multiple versions will normally use the highest version available from a server, so many machines will see a change.
There are many internal differences between version 3 and version 4, some of which may lead to improved performance.
