I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g.
IET http://iscsitarget.sourceforge.net/
SCST http://scst.sourceforge.net/
Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to imply that it's what's being used in RHEL.
Does anybody know for sure?
