pause will normally cause head-of-line blocking on congested links because it applies to all traffic on a link. pfc will attempt priority based frame delivery and can be less disruptive depending on traffic profile. In other words, pfc is a more granular form of pause and allow you to choose what priorities are paused based on CoS. The key in the Dell situation is that they're using mixed frames. If you have just iscsi traffic on a link, all of the same priority, then there will be no practical difference between the two.
