Dear Bob,

thank you for your comments.

So for scaling up the cluster we have two possibilities:

upgrade the hardware of single nodes
add additional nodes to the cluster

I wonder how to decide when to perform which action.

Is this really all one can do or does one have something like a strategy when planning the cluster?

Regards,
Magnus
