Only technical difference I can think of is the iSCSI-level<br>
load-balancing. With NFS you set up the network with LACP and let that<br>
load-balance for you (and you should probably do that with iSCSI as well<br>
but you don´t strictly have to). I think it has to do with a chance of<br>
trying to go beyond the capacity of 1 network interface at the same<br>
time, from one Host (higher bandwidth) that makes people try iSCSI<br>
instead of plain NFS. I have tried that but was never able to achieve<br>
that effect, so in our situation, there´s no difference. In comparing<br>
them both in benchmarks, there was no performance difference at all, at<br>
least for our storage systems that are based on FreeBSD.<br>
