Redundancy

  • The LAN and SAN design features redundant components and connectivity at every level to ensure that no single point of failure exists. The design enables the application server and the backup system to reach the database server, and the database server to reach the storage array, even if any of the following components fail:

    • One or more CNA or mezzanine card ports within the MX840c compute blades
    • One MX9116n IOM or switch
    • One or more PowerMax front-end ports
    • One PowerMax storage controller
    • One or more 10 GbE front-end interfaces within the DD9300 backup system
