I have run clusters with different disk size nodes by using different number of
num_tokens. I used the basic math of just increasing the num_tokens by the same
percentage as change in disk size. (So, if my "normal" node was 8 tokens, one
with double the disk space would be 16.)
One thing to wat
ncy if the
token figure were the same across all nodes?

If you set a different num_tokens value for new hosts (the value should
never be changed on an existing host), the amount of data moved to that
host will be proportional to the num_tokens value. So, if the new hosts
are set to 32 when they're added to the cluster, those hosts will get twice
as muc
You shouldn't need to change num_tokens at all. num_tokens helps you
pretend your cluster is a bigger than it is and randomly selects tokens for
you so that your data is approximately evenly distributed. As you add more
hosts, it should balance out automatically.
The alternative to num_tokens is
