Set up physical network. Rack and cable all network switches. Install Cumulus Linux. Verify all cables are properly connected as expected. Use ptmctl as needed. 2. Set up basic configuration of all switches. Configure basic items for management such as eth0, hostname and DNS. Network Topology 3. Configure leaf switches. Configure an individual switch and then automate for remaining switches where possible. 4. Configure spine switches. Configure an individual switch and then automate for remaining switches where possible. 5. Configure edge leaf switches. Configure switches individually and configuration for connections to core. 6. Verify configuration. Ensure your topology matches your planning. 7. Connect network fabric. Connect leaf switches to spine switches. Host Setup 8. Install base OS. Install the OS into each bigdata# node. 9. Ensure common services are set up. DNS, DHCP or other dynamic common services. 10. Begin installation of Hadoop. Follow the recommended process in the Hortonworks Hadoop guide. In a green field environment, the order of configuring spine or leaf switches does not matter; that is, they may be reversed. In a brown field environment, start with leaf switches and finish with the connections to the core for minimal network service disruptions.
