The need for Network attached Storage *„A storage area network (SAN) is a network designed to attach computer storage devices such as disk array controllers and tape libraries to servers.“ Its primary purpose is the transfer of data between computer systems and storage elements. A SAN consists of a communication infrastructure, which provides physical connections, and a management layer, which organizes the connections, storage elements, and computer systems so that data transfer is secure and robust. The term SAN is usually (but not necessarily) identified with block I/O services rather than file access services.

The Future of Fibre Channel? LRTV: Do you think Ethernet is eventually going to take Fibre Channel’s place in storage networks? Is it robust enough? Bob Metcalfe: Absolutely, it is. Fibre Channel’s doomed.
LRTV: Really? How long do you think it’s going to take before companies like Brocade start having a really hard time? Bob Metcalfe: It’ll be over in ten years.

Summary Use SAN Infrastructure to provide any-to-any connectivity and build an enabling platform for advanced information management techniques. Implement SAN Routing to connect and consolidate distributed SAN islands and to enable state-of-the-art business continuity solutions (e.g. mirroring) Routing enables secure, unified storage access across heterogenous platforms and across distances Network based provisioning and virtualization (e.g. IBM SVC) provides significant benefits over traditional host/storage based solutions. © 2003 IBM Corporation
