Hi Jeff,

        If you look at:

http://www.netapp.com/osn/info/config.html

        You will see a network based backup configuration that
        sends the backup data over a dedicated IP network
        or IP SAN. The storage is accessed from clients via
        NAS protocols (NFS & CIFS) and not via a FC SAN. The
        first solution available is the ATL (http://www.atlp.com)
        P3000 with a 100bT connection supporting DLT 7000 tape
        devices.

        In a recent InfoStor article:

http://is.pennnet.com/Articles/Article_Display.cfm?Section=OnlineArticles&SubSection=Display&PUBLICATION_ID=23&ARTICLE_ID=98555

        they mention that they are working on their next
        generation which will also support SDLT & LTO.

        "This amounts to converting its libraries from 100BaseT
        Ethernet to Gigabit Ethernet to match the performance
        requirements of this new class of drives."

        The ATL library has an NDMP (http://www.ndmp.org) tape server
        built in which provide tape device contention management/
        allocation so there is no need for SSO when using this
        network resource for backups.

Cheers,
        Grant
