Sometimes tens of scalars per second is the sampled data. It depends upon your requirements for accuracy and responsiveness for alarms, threshold checks, etc.

Sometimes tens of scalars per second is the sampled data. It depends upon your requirements for accuracy and responsiveness for alarms, threshold checks, etc. I work with paper making machines that only give us a profile every 30 seconds--but that profile is a thousand floats, and we need to be constantly resampling it both spatially and temporally, and we're doing that for tens or hundreds of profiles for a single system--and we're supposed to handle hundreds of systems. The more fundamental point that the GP is making is that the realm of industrial sensor data scales in ways that people haven't really grasped yet. It's much less about brute storage than it is about the interplay between bandwidth, storage, and concurrent processing power.
