I assume that you are looking at transfer of large amounts of data over 40G
links. Assuming that tis is the case, yes, multiple connections per session
can help you. If you have not done so, you should also look at
http://fasterdata.es.net. It is a bit linux-centric these days, but still
provides a lot of information on moving data efficiently over fast links.
IIt is evolving continually, but did not discuss iSCSI last I knew.

ESnet has an Nx100G backbone and many users (most notably the LHC at CERN)
who regularly move increasingly large volumes of data, often around the
clock, making efficient use of available bandwidth is critical. The network
researchers there have put in significant efforts in determining how to
best optimize such operations.
