We have 14,000 nodes and 1 core server.
It is a pretty delicately balanced affair, that requires fairly frequent tweaking (IIS/LD/OS) depending on the loads from the different tasks being undertaken.
1. Would this task be easier with the load spread over more core servers, or would the tasks of maintaining more boxes cancel that out?
2. What nodes to core server ratios are people running, and would they recommend them?
