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.
