Solved
codyhostermanI can see you have written several articles about ISCSI and MPIO
but I can not see if port binding is supported with multiple subnets, or if it makes sense to use at all?

Generally I always recommend port binding because without it it is harder to track what NICs are being used or not used for iSCSI. Without it, the routing tables will be used which isnt a bad thing but just makes tracking/management trickier. For multiple subnets there used to be a benefit there for a path limit perspective but now that VMware supports 32 paths keeping the count down is less important (not all paths are available down all iSCSI targets with multiple subnets). There can be some benefit from availability to multiple subnets if certain ones are owned by specific switches. We dont really have a specific recommendation on subnets, but we do encourage port binding when possible
