Few additional things. 1) my apologies, lotus notes is the devil and did all sorts of terrible things to the formatting of initial post when viewed on http://lists.wpkg.org/pipermail/stgt/2011-September/004782.html 2) I have yet to see anyone post a detailed setup / results showing 1000+ MB/s throughput between open-iSCSI and stgt, so hopefully this helps people. 3) I am surprised the iops are so low for small block tests, kind of makes you wonder about the validity of the splash page of http://www.open-iscsi.org/ which boasts 50k+ iops with small block sizes. Using a ramdisk eliminates the storage as a contention point so really all that is left is the initiator and the target. 4) tgt-admin needs some serious updating/work/rewrite, missing many flags / cant add nullio devices via it etc etc. My patch for bsflags is the tip of the iceberg as far as problems with that tool.
