Whenever a single point of failure can be removed, it should be.
If it is cost effective. In the case of interface cards it is but then add in the cost of using two ports for each network your one system is on...more switches are needed, folks complain about running out of IP addresses...some battles are not worth it. If you had a SUN E10K, you would have to buy a second because of the single point of failure that is internal to it. Quite costly.
