The rapid spread and adoption of production storage area networks (SANs) has fuelled the need for multiprotocol routers. The routers provide improved scalability, security, and manageability by enabling devices in separate SAN fabrics to communicate without merging fabrics into a single, large SAN fabric. This capability allows clients to deploy separate SAN solutions at the departmental and data center levels. Then clients can consolidate these separate solutions into large enterprise SAN solutions as their experience and requirements grow and change. Alternatively multiprotocol routers can help to connect existing enterprise SANs. For instance, the introduction of Small Computer System Interface over IP (iSCSI) provides connection of low-end, low-cost hosts to enterprise SANs. Using an Internet Protocol (IP) in a Fibre Channel (FC) environment provides resource consolidation and disaster recovery planning over long distance. And using FC-FC routing services provides connectivity between two or more fabrics without merging them into a single SAN. This IBM Redbook targets storage network administrators, system designers, architects and IT professionals who are engaged in the selling, designing, or administration of SANs. It introduces you to the products, concepts, and technology in the IBM TotalStorage SAN Routing portfolio. It shows the features of each product and examples of how you can deploy and use them.
