Which performs better under heavy load with lots of random file IO? I am particularly interested because our environment has been build around iSCSI. There is a possible shift in a core technology for us which may shift us from a SAN using iSCSI to a NAS using either NFS or SMB so we, too, are quite interested in others' experiences. Thanks - John SANs will almost always perform better than NAS', FWIW. NFS has the better load handling and has good locking (provided you run it as recommended with portmap, statd, etc.) Samba is primarily used to share files to windows hosts. The security architecture of NFSv3 and earlier is based on simple UID reliance. You can stop root access altogether, and there's little concern of NFS leading to a system being corrupted, but it IS technically possible for a malicious user to delete other users files if you have write allowed. NFS is usually used in environments with trusted users (i.e. share only to specific machines, not the world). -- Liam
