This really isn't the place to ask about iSCSI targets, by the way. This list is for discussion of the open-iscsi iSCSI initiator package. But I'll try to answer your questions. > > 1 \ both lio-utils and tgt are pure user space program? Both of them are > using the kernel iscsi module ?

The transport is handled by the kernel. See http://stgt.sourceforge.net The lio-utils package is being deprecated in favor of the targetcli package. Right now, targetcli works on top of lio-utils, but soon it will run standalone. See http://linux-iscsi.org/wiki/Lio-utils The lio-utils/targetcli combo is configured in user space, but managed in kernel space. There is no user-space daemon running in this case. Difference between them: plenty. Configured differently, different designs, and the Linux community has chosen targetcli moving forward. I have *not* benchmarked them, so I have no idea if one performs better than the other. Also, targetcli doesn't yet have every feature that tgt has, such as iSNS support, but targetcli is being actively developed/improved. 2 \ Are there any guide documents on how to setup a iscsi target using both > tgt and lio-utils? > I have created some simple example documents, but they are SUSE-based. I haven't published them yet, but was thinking of setting up some place where I could do that. I could probably email them to you if you thought they might be useful. Note: if you use targetcli, try the manual page, as it has enough information to set up a simple target. > > Thanks a lot for your help and time ! > > -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
