Consider then reading http://en.wikipedia.org/wiki/Iscsi your homework 
.. ;-)
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' . So 
they are serving different needs. While multiple hosts can access 
directly a NFS exported fs, iscsi share a block device (target) to an 
initiator host (or multiple hosts). Except if you're using a cluster FS 
like GFS, you can't access the same lun from multiple initiators at the 
same time
