    Problem:
    Netbackup Datacenter 4.5 trying to configure network interfaces for best
    utilization.

    Scenario:
    1-V480 with 4 cpus and 8g ram. I have 2 gigE on board network connections
    and 2 gigE pci cards (in the 33MHz slots). 2- Qlogic HBAs for Hitachi 9980
    SAN connection. (in the 66MHz slots). Running Solaris 9, current with all
    patches. Connected via scsi to L700e with 11 Lto gen 2 fibre attached
    drives. These are connected to Brocade switches running 2GB.

    Dilemma:
    I have a frontend and a backend network. I want to setup 2 of the
    interfaces on the frontend and 2 on the backend network. I would like each
    network to have one hostname that is known to the other servers.
    I'm contemplating IPMP. I've read the documentation, several times and the
    summary of the blueprints. I'm not yet comfortable that this will work. I
    read on a previous summary that IPMP only works on outbound traffic for load
    balancing, which I don't believe would buy me anything. The other option
    I'm thinking about is Sun trunking. I've looked over the documentation and
    it states it only load balances on outbound traffic as well, plus I can't
    seem to find any documentation past Solaris 7.
    I would appreciate any insight anyone is willing to share. I have searched
    the summaries, google, sunsolve, docs.sun.com, bigadmin etc. This issue is
    starting to drive me crazy or I would not be posting. I will definitely
    summarize.

    Thank you,
