What happens if your server is connected to its storage through a network switch, and that switch goes down? Your server can’t communicate with its storage any longer. With Multipath I/O, you can allow your server to use multiple paths to your SAN — you could have connections through two separate switches, for instance. If you have connections to two separate switches, your server will still be up and able to access its storage even if one of the switches goes offline. This allows you to build a truly fault-tolerant storage network.
