Square Enix is best known as the developer of the two epic RPG series Final Fantasy and Dragon Quest. A high-capacity network is required in game development. The previous network also had 10Gbps ports on the core switch, but the new network required bandwidth of tens of Gbps on a distribution level. Operability and stability were also essential requirements. The reason for this is that development is interrupted if the network stops. They chose Cisco to overcome these challenges. By using the Cisco Nexus 7009 in the core and the Cisco Nexus 5548UP for distribution, it was possible to create a wide-bandwidth high-performance network able to provide speeds of up to 100Gbps on a distribution level and network stability was also increased.
