I think your math is 'relatively' correct. It would seem to me you
should focus on how you can reduce the amount of storage you are using
per item, if at all possible, if that node count is prohibitive.

Hi,
One of the projects I am working on is going to need to store about
200TB of data - generally in manageable binary chunks. However, after
doing some rough calculations based on rules of thumb I have seen for
how much storage should be on each node I'm worried.
200TB with RF=3 is 600TB = 600,000GB
Which is 1000 nodes at 600GB per node
I'm hoping I've missed something as 1000 nodes is not viable for us.
cheers
