In round robin (VMware) the host uses an automatic pathselection algorithm rotating through all
available paths. This implements load balancing across all the available physical paths.
Load balancing is the process of spreading server I/O requests across all available host paths.
The goal is to optimize performance in terms of throughput (I/O per second, megabytes per
second, or response times).
