Installation guide

But in general, please take into consideraon that memory requirements per instance are reduced when the same user populaon is
distributed over mulple nodes. In this case:
Assuming the same user populaon N number of nodes M buer cache for a single system then
(M / N) + ((M / N )*0.10) [ + extra memory to compensate for failed-over users ]
Thus for example with a M=2G & N=2 & no extra memory for failed-over users
=( 2G / 2 ) + (( 2G / 2 )) *0.10
=1G + 100M
