Hello,
I don't know what pelops is. I'm not sure why you want two clusters. I
would have two clusters if I want to have data stored on totally separate
servers for perhaps security reasons.
If you are going to have the servers in one location then you might as well
have one cluster. You'll have the maximum aggregate io of all the servers.
If you're thinking of doing analytics as well then you can create two
virtual datacentres. One for realtime inserts and reads and the second for
analytics. You could have have and 16 /8 server split. Obviously you'll
have to work out what the optimum split is for your workload.
Not sure if I've answered your question...
