The Cisco MDS 9222i Multiservice Modular Switch, the next generation of the highly flexible, industry-leading, proven Cisco MDS 9200 Series Multilayer Switches, is an optimized platform for deploying high-performance storage area network (SAN) extension solutions, distributed intelligent fabric services, and cost-effective multiprotocol connectivity for both open and mainframe environments. With a compact form factor, modularity, and advanced capabilities normally available only on director-class switches, the Cisco MDS 9222i is the ideal solution for departmental and remote branch-office SANs.Sharing a consistent architecture with the Cisco MDS 9500 Series Multilayer Directors, the Cisco MDS 9222i offers 18 4-Gbps Fiber Channel ports and 4 Gigabit Ethernet IP storage services ports and a modular expansion slot to host Cisco MDS 9000 Family switching and services modules.As the storage network continues to expand, the Cisco MDS 9000 Family switching modules can be removed from the Cisco MDS 9222i modular switches and migrated to Cisco MDS 9500 Series directors, providing high flexibility, smooth migration, common sparing, and outstanding investment protection.
