The role of data networks in daily lives continues to expand and grow. Emerging needs such as application convergence, non-stop operation, scalability, and IPv6- readiness place new demands on the network. Modern network solutions must be assessed across a wider set of attributes than earlier generations of equipment. In particular, the network must be evaluated on merits that include performance, reliability, scalability, Quality of Service (QoS), security, and Total Cost of Ownership (TCO). The Brocade BigIron RX Series of Layer 2/3 Ethernet switches excels in all of these areas, enabling network designers to deploy an Ethernet infrastructure that addresses today's requirements with a scalable architecture designed to support network growth and evolution. The BigIron RX Series incorporates the latest advances in switch architecture, system resilience, QoS, and switch security in a family of modular chassis, setting industry-leading benchmarks for price/performance, scalability, and TCO.
