Hi all,

Say we have 2 datacentres with 12 nodes in each. All hardware is the same.

4-core, 2 x HDD (eg, 4TiB)

num_tokens = 16 as a start point

If a plan is to gradually increase the nodes per DC, and new hardware will have 
more of everything, especially storage, I assume I increase the num_tokens 
value.  Should I have started with a lower value?

What would be considered as a good adjustment for:

Any increase in number of HDD for any node?

Any increase in capacity per HDD for any node?

Is there any direct correlation between new token count and the proportional 
increase in either quantity of devices or total capacity, or is any adjustment 
purely arbitrary just to differentiate between varied nodes?

Thanks

M
