Best NIC Setup for HyperConverged 2012R2 2 Node

I am using 2 identical servers spec'd as below:
- Dell PowerEdge T610
- Dual Xeon E5600 series CPUs
- 72GB RAM
- 4x1TB RAID 10 (OS / Data on same array, OBR10)
- 4x 1GB NIC (2x onboard, 2x PCIe on single card)

What I would like to do is maximize my iSCSI layering so if NODE1's SAN layer goes down for some reason and the NODE remains active from a cluster standpoint, when it fails over it will utilize multiple NIC's for iSCSI.... IE:
- 127.0.0.1 used for primary
- x.x.x.1, x.x.x.2, x.x.x3 for failover w/round robin type mentaility

Not even sure this is possible. Running about 12 VMs between the two systems including Exchange, DC, SQL...

Hello jdube,
Thank you for interesting in StarWind solution
Let's imagine you lost the Underline Storage for StarWind on the first host. In that case, the node will remain active in the cluster, but StarWind storage connected on it will be available via all iSCSI partner connections from the second node.
Please note that with MPIO Failover only policy, failed node will connect to partner target via only one path while with Round Robin MPIO policy all available paths will be in use
In Hyper-Converged scenario, with 1 Gbps iSCSI connection, I would recommend use Failover only MPIO policy and mark loopback connection (127.0.0.1) as active.
