For how many Data blocks my cluster will support.

[#1]

Hi team,

on my cloudera hadoop cluster every day 1TB data is loading and it has almost 17,811,802 data blocks. Right now the performance is good. 

I want to know and calculate for how many data blcoks my cluster will be support ? without performance issue.

In one of the Blog i read for 1000000 data blockes 1 GB ram required from name node is it true ? 

we have 18 Node cluster every node in my cluster has 380 GB RAM.
