I have a two host vSphere Enterprise v5.5 setup and am about like to deploy NSX.
To operate one host in "active" and the other in "standby" do I need to license NSX on both hosts?
VMware NSX is available with either a perpetual or term license. perpetual license are per CPU, and term licenses are per virtual machine per month.
there is nothing like active/standby for the ESXi host when you deploy NSX but you do have active/standby mode available for NSX edges
