Head Node with More Memory and less number cores

Hi,

I have question around cluster configuration, Is there any benefit of 
having Head node with more memory and less number of Cores. I have Data 
Nodes of Size 10 Nodes each of 4 Core and 14 GB RAM. Can any one throw 
me some light of having Head node with Big Memory. How exactly Head Node 
memory is indirectly responsible for Cluster Node Size.Will there be any 
performance improvement (I don't think so) or any resource outage issues 
get resolved by having more memory in head node.


Thnks,

Mahender
