SCv2000 "One iSCSI Network with Dual 1 GbE 4-Port Storage Controllers" - vSphere Design Guidance?

Given the "One iSCSI Network with Dual 1 GbE 4-Port Storage Controllers" design described in the Dell Storage Center SCv2000 and SCv2020 Storage System Deployment Guide (page 47), what is Dell's generally recommended iSCSI design (including vSwitch layer) for a 2-node vSphere 6.x HA cluster using VMware's software-based iSCSI initiator?

For the vSwitch layer, I'm primarily interested in high-level design guidance regarding the number of iSCSI vSwitches per host and iSCSI port binding recommendations.

If feasible, please include an example iSCSI IP address config (SCv2000 fault domains and vSwitch layer) in your reply.

Otherwise, please just share any insights that you have about the subject.
