It is from a few years ago but the datapoints are very relevant. http://linux-iscsi.org/builds/user/nab/Inter.vs.OuterNexus.Multiplexing.pdf The key advantage to MC/S and ERL=2 has always been that they are completely OS independent. They are designed to work together and actually benefit from one another.
