Tom Hollingsworth looks at the issue of network reliability. At Aruba Atmosphere, he saw some impressive reliability features, including a live non-disruptive controller upgrade during one of the presentations. Tom found it impressive, but thinks a lot of the focus on reliability, is perhaps not seeing the forest for the trees. For Tom, maybe the idea of creating incredibly robust networks that absolve users from error, Tom calls for more limitations and responsibility for people working on and using them. A little knowledge goes a long way to absolving an organization from the expense of designing an implementing the “foolproof” network.
