Configuring Equallogic PS4100 and HP MSA2312i in ESXi 5 Environment

I have a three host, ESXi 5.0 environment.  I have a Equallogic PS4100 SAN for my production environment.  My current vswitches use four VMkernel ports, with Round Robin, etc.  I am using the Software iSCSI Adapter.  I want to connect my HP MSA2312i to the hosts for some non-production level virtuals and as a target for a few critical vm replicas in case something should ever happen to the equallogic.  

So my question is about the proper networking needed.  Do I need to remove some of the nics from my current vswitches to set up separate vswitch to handle the traffic for the HP MSA?  Or, will VMware handle the different iSCSI targets properly.  I believe the Dell and HP have different recommendations in terms of subnetting, so that probably answers my question right there, but I thought I would put it out there for any real world advice.

I would leave existing configuration in place and add new physical nic.

Use exactly the same network design just connect MSA to same storage network

Are you using Equal logic multipath module and modifications if so I would recreate and define new vSwitch physical NICs etc

I am using the multipath module.  So I should split the nics, or better yet, add another nic card to each server so that I don't have to sacrifice available paths to my production storage?
