EMC VNX stories all start with "Back in my day..."

TL;DR EMC VNX IS your grandfather's SAN Per " Using EMC VNX Storage withVMware vSphereVersion 4.0 " published 2015-JAN, does not support vSphere " Multipathing Configuration for Software iSCSI Using Port Binding " (aka MPIO). Port binding is not new, Virtzilla's whitepaper was published in 2012, but EMC likes the old days. EMC recommends "implicit assignment", which relies on the ESXi TCP/IP stack determining the correct vmkernel port based on directly connected networks.  If it is still profitable, why improve it? Unfortunately, customers pay for, and expect, an Active/Active SAN and only get half. Now get off my lawn!
