Stateful Network Filesystem vs. NFS

SheMoves · 07-12-2008, 06:25 PM

How would a stateful network filesystem differ from NFS?

I understand that NFS does not hold information about which client is working with which file. Performance problems are an issue because file system modification commands are not fixed on disk before remote procedure call request can be answered. Also, NFS does not provide any encryption. I can't find information about stateful network filesystem???? Help!

You can get help by reading stuff. E.g.,
http://publib.boulder.ibm.com/infoce...ngd/nfs_v3.htm
http://media.netapp.com/documents/NFSv3_Rev_3.pdf
and particularly
http://www.hummingbird.com/support/n...945.html?cks=y - you should definitely see the section
