ArcelorMittal Ostrava is the largest steelmaker in the Czech Republic, and their local factory is a part of the ArcelorMittal steel and mining group. ArcelorMittal Ostrava‘s network environment has been running for twenty years, uniquely combining old and new technologies while maintaining efficiency and investing in cutting-edge IT solutions. Due to the legacy network and the challenge of managing a multi-vendor environment, ArcelorMittal decided to search for a new network management tool to begin upgrading their network. After an exhaustive search for the right fit, the IT infrastructure department decided to purchase the all-in-one solution from Extreme Networks.



  • Provide centralized network management software for a multi-vendor environment, while reducing the time and resources required to operate the network
  • Unify network management for existing multi-vendor infrastructure
  • Deliver visibility and control of devices, users, and applications accessing the network
  • Automate secure guest network access
"With Extreme Management Center, there is  a significant value-add for administrators. Now we can manage ports and configurations throughout the heterogenous network, including Catalyst 6500 series switches with a CatOS operating system. We realized after testing other vendors that if we got a real, unified management system, we could gain network visibility and control never before attainable."
