What is the difference between iSCSI and NFS/CIFS?
iSCSI and NFS (Network File System) or CIFS (Common Internet File System – MS proprietary network filesystem) all allow storage access over IP networking infrastructure. However, iSCSI enables block storage transfer while NFS and CIFS transfers files. Ultimately a file is composed at the NFS/CIFS server device through block level storage access. Block level storage access offers superior performance for data intensive software applications and databases.
