There's at least 'chasis' that some people would want to add (blade
based stuff) and I'm not sure what standard 'module' is... The trouble
with standard definitions is that your standards rarely match the next
guy's standards, and since some of these are entirely irrelevant to
many storage topologies, you're likely going to need an API to
discover what is relevant to a specific system anyway.
