Mainframe storage networks carry the world's most mission-critical applications. As AI and data demands accelerate, that foundation has to evolve. Cisco MDS 9000 Series Multilayer Switches deliver the speed, security, and scalability modern storage area networks (SAN) need—from 32G to 64G performance. Security is built into every layer. Anti-counterfeit technology and advanced Fibre Channel protocols form a multilayered defense. AI-powered management keeps production workloads secure, stable, and always on. SAN Analytics in Cisco Nexus Dashboard gives you real-time monitoring and performance troubleshooting across the entire SAN fabric, from fabric configurations to port-level traffic. FICON Control Unit Port (CUP) enhanced support and certification unlock mainframe performance faster. Tools like Resource Measurement Facility (RMF) help you manage storage network performance, spot bottlenecks, and track director activity, with topology discovery now driven directly by z/OS systems. Whether you need fully redundant MDS directors, the compact MDS 9148V for distributed environments, or advanced SAN extension with the MDS 9220i, Cisco MDS 9000 Series switches deliver native FICON support and enterprise-class resilience. Keep your mission-critical operations fast, secure, and always on with Cisco MDS 9000 Series Multilayer Switches.
