NFS 4.1 Enhancements -- Statement of Intent
December 10th, 1991
The Information Networks Division received formal signoff on Friday,
December 6th to proceed with the development of a set of enhancements
for NFS. These set of enhancements will include much demanded NFS 4.1
functionality and performance enhancements.
IND's plans include making the enhanced version of NFS available for
our Customers with HP/UX 9.0, currently scheduled for Summer of 1992,
and HP/UX 8.3, also currently scheduled for Summer of 1992. With these
two releases, the enhanced NFS will be available for all HP/UX systems;
Series 8xx, 7xx, 3xx and 4xx.
Enhancement Set Detail:
------------------------
In more detail, IND commits to providing the following enhancments:
From SUN's NFS 4.1:
FOR HP/UX 9.0 and 8.3
---------------------
Export of Root: Allows the NFS server to export Root capability to NFS
clients
Export Read-Only: Allows the NFS server to export Read-only capability
on a file or directory to the client.
Directory Exports: Allows the NFS server to export individual
directories and subdirectories to a client, instead of forcing exports
to take place at the file system level only.
Automounter: {Automounter is currently available with 8.07 for the
series 7xx} Automounter is a program which allows NFS mounts to occur
dynamically for ease of administration. When the client user or
application attempts to access an NFS remote file, the mount is
automatically established, and times out after a certain inactive time
limit occurs, thus eliminating unused mount points and stale file
handles.
Updates: With NFS 4.1 the following features have been updated:
rpcinfo
showmount
NFSstat
We will incorporate these updates into our NFS with HP/UX 9.0 and 8.3.
Additional Enhanced Functionality:
----------------------------------
In addition to the above enhancements, we will be adding in the
following mount command options for HP/UX 8.3. We are investigating
adding these to 9.0 as well, but cannot commit to that today.
NOAC option
NOCTO option
Opportunities we are Investigating: *not committed*
-----------------------------------
We are also investigating updating rpcgen and pc-nfsd to the 4.1
versions, however, we cannot commit to this at this time. If there is
sufficient need, we will aggressively attempt to get the updates into
the releases.
What we are Definately NOT Doing:
---------------------------------
The following 4.1 functionality is NOT planned from HP:
Secure RPC: HP is committing to Kerberos as our strategic security
solution
POSIX Pathconf Support
Dynamic Retransmission: We are currently investigating performance
enhancements for dynamic read and write sizes. Sun's implementation of
Dynamic Retransmission was pulled from NFS 4.1 due to bugs.
NetDisc: DUX is our current diskless solution
Revised Lock Manager: HP has their own version of lock manager
New version of NIS in NFS 4.1: HP has added much value-added
performance enhancments in NIS. These performance enhancements are not
found in NFS 4.1 from SUN.
SUMMARY:
--------
HP has committed to providing the highly-requested features found in
NFS 4.1; Directory exports, export of Root, Read-only exports and
Automounter. We will be adding these to HP/UX 9.0 and 8.3.
