Seemingly small network events can have ripple effects and trigger an outage downstream, especially for WSFCs. Network segmentation can help isolate and prioritize certain types of traffic. Performance-oriented settings can also boost the speed of this interconnect architecture.
Network architecture is rather straightforward at first. Connect a physical host to more than a single switch to ensure redundancy in and out of the host. There should be multiple physical NICs – not just multiple ports on a single NIC – to connect the server to these switches.
