I would use IPv6 for the orchestration network, probably not touch the tcp/ip parameters except for port range (and open file descriptor), and break up the broadcast domain into smaller networks. It is not advisable to have thousands of machines on one broadcast domain, and it is a pain in the ass to troubleshoot, not to mention causes bigger headaches when one network problem affects all the nodes across the entire gigantic network.
