   namesrv manage broker info and topic info and store all info in the memory,so i think 16g mem is more 
   suitable,but if your topic and queue are relatively few,8g is OK。for 3 broker, i think 2 namesrv is OK.
   and only master may lost messages.
   so 2M - 2S is adviced。
   There are some configuration we are using now
   2 namesrv: 8cpu and 16g
   4 cluster,per cluster have 2 master and 2slave.
   broker : 2M-2S.
   3E messages a day.
