On 13.1 and earlier, I have installed 'iscsitarget' (ietd), but that's not available in Leap 42.1 ? I can't see another iscsi server either - can someone point me in the right direction? ISTR something about ietd being deprecated in favour of lio, but I can't find that either.
I'm not sure about deprecation, but as far as I understand LIO is kernel based, so only configuration tools exist.
Yes I see that now, thanks. We've been using iscsitarget (http://iscsitarget.sourceforge.net/) for a couple of years, but as I am setting up a new set of storage servers, I wanted to see what else is out there. With 'deprecated' I meant in open/SUSE where we clearly favour LIO/tcm. Hannes Reinecke is active in LIO development, I think. It would also appear that IET/iscsitarget is falling behind featurewise. I found this comparison table, but I can't tell how un/biased it is: http://scst.sourceforge.net/comparison.html It seems that SCST is an IET fork, which appeals to me as we already have IET running. Then I came across a very recent thread on linux-scsi about a proposed LIO/SCST merger, but the LIO and SCST guys don't seem overly friendly to one another. https://www.mail-archive.com/linux-scsi@vger.kernel.org/msg46756.html
From having googled a good few hours, I feel only minimally better informed, but for some reason I tend toward SCST. Both LIO and SCST seem to be backed/sponsored/supported by corporate entities - Datera and Sandisk respectively?
This article describes exactly what I intend to build, but neglects to make a recommendation wrt which iscsi target implementation: http://www.nnc3.com/mags/LJ_1994-2014/LJ/217/11275.html Would anyone else care to add their opinions? -- Per Jessen, Zürich (4.3°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This is correct.

This table is *kind* *of* accurate. I plan on building a non-biased table this year and publishing it, but I don't have one yet.
It seems that SCST is an IET fork, which appeals to me as we already have IET running.

This is getting better. Currently, upstream, we are taking the best (not duplicated) parts of scst and feeding them upstgream. The lio/targetcli kernel-based target seems to have "won", for now.

Would anyone else care to add their opinions?

Okay, thanks for the reply - I've been growing fond of lio/targetcli recently. /Per Jessen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
