Hi,

I am reading through issue 8 as I am considering to build a new solution to hold a huge number of mailboxes (hopefully some 500.000). I am now starting to consider the requirements for a test model and I am not sure of how many machines are involved. The text says that “the design enables N+1 relay servers” (page 17).
Can anybody please clarify which is the value of N? I can’t find it anywhere in the text.

Thanks in advance,
J.

The term N+1 is used to define scalable solutions, so N can be any value. The solution should be able to handle as many relay servers as you can throw at it.
