Don't try to compare NFS and iScsi : they aren't working at the same level : iScsi works at the 'block level' while other Network File Systems (like NFS, CIFS, etc ...) work more at the 'file level'
Hmmm. CIFS works at block level (SMB == Server Message Blocks). iSCSI is a transport protocol while CIFS and/or NFS a file systems :)
SMB despite it's name does not work on the block level, but the file system level.
CIFS/NFS are ways of extending the file system across the network.
iSCSI is a way of extending the disk drive or array over the network. It's a subtle by important difference.
