Hi to ya all, this might be interesting question here...
We have fairly stable cluster now with 10 nodes running smtp and pop3.
We divided service across cluster so we have 6 smtp nodes and 4 pop3 nodes.
I'm not sure why this was the setup but it is ;)
Does anyone know is there performance penalty for such distribution of
services or one unified node running both services (smtp+pop3) would
somehow do better?
How i see this is that it is better to have one unified node both for
better distribution when there is a higher load on one service and also
easer replacement of failed nodes, but is there something related to how
gfs is operating to support this theory?
I plan to conduct some light testing using three nodes in simulated
workload environment to actually see is there a feasible difference or
this is all marginal philosophy.
I think this also might be a good pointer when people do cluster
planning so I'm anxious to here some comments ...
