Multiple logical and/or physical networks are recommended for segmenting and isolating certain workloads. Some common network traffic that are usually segmented include:
● Host management
● Live Migration communication
● Storage connectivity and communication if using iSCSI or shared storage presentation such as Cluster Shared Volume(s) commonly referred to as a CSV
● WSFC-level communication
● VM communication
For example, iSCSI traffic should be isolated to reduce broadcast traffic, improve security, and allow for QoS prioritization to improve and add consistency to storage traffic performance.
