There is a limit on the number of RANGE partitions. Something like 2048 if I remember correctly. Shouldn't be an issue with your strategy.
Will you be using different storage for the different partitions? Or sets of partitions? I ask because you mention that you have 60 devices but don't mention how you will be placing and isolating partitions. Do you plan on using multiple dbspaces for this?
It is quite easy to collapse/remove partitions so that your daily partitions become weekly or monthly. The only requirement is that the current daily partitions reside on the same dbspace.
Can you elaborate on what you want to accomplish by using partitions?
