ESX Server hosts can use multipathing for failover. When one path from the ESX Server host to the SAN
becomes unavailable, the host switches to another path. ESX Server hosts can also use multipathing for load
balancing. To achieve better load balancing across paths, administrators can specify that the ESX Server host
should switch paths under certain circumstances. Different settable options determine when the ESX Server
host switches paths and what paths are chosen
