Hi:

Really, a quick search of docs.hp.com titles provides:

Shalom,

NFS V4 provides a better file locking mechanism and much better performance.

It is only currently available in HP-UX 11.31

Hi,

Let's approach this from the opposite direction. Are there features in NFS v4 that you think you could benefit from that are not available in NFS v3? If so, I'd love to hear what they are. Is there something NFS v3 is not providing you that you think you can get by moving to v4? If so, please let me know what that is.

Regards,

Dave

Hi,

Use of one network port
To help NFS setup for internet use, one unique network port is used on NFSv4. This predetermined
port is fixed. Default is port 2049.
a) Consequences:
â ¢ Using NFS through firewalls is easier.
â ¢ portmapper is no longer required.

--------------------

In order to ensure a better reliability over the Internet, NFSv4 only uses TCP.
-------------------------------
IPv6 protocol is supported on the client side.
----------------------
NFSv4 uses 32 KBytes pages.
-------------------------------
NFSv4, unlike its predecessors, brings together in the same protocol most file system management
tools. NFSv4 only requires the servers below to be launched :
â ¢ rpc.nfsd (nfs server)
â ¢ rpc.idmapd (identifier server)
a) Consequence
Tools such as rpc.lockd or rpc.quotad are no longer required.
