Ram allocation plan by couchbase

I wonder if you explain or provide me a link to clear ram allocation by couchbas.
I mean, how many percent of total allocate for replica,for active data,for user request,for write data ,so … and the priority of them.

for example in above image,what is orange area before red line(arrow 5), what is that after red line, why it is continuing after red line, what is “other Data” while i only have one bucket and in this time(I mean when i catch this image) I only import data and there is no replica.



You can see detailed information in the doc:
