Network Card Teaming - best configuration for DFS-R?

    Hi I was wondering if anyone has any recommendations for the best
    configuration for Network Card Teaming when using DFS-R?

    We are running a couple of HP servers with 100/1000 dual NICs. They are
    currently set to: Transmit Load balancing with fault tolerance (TLB)

  2. The give the Microsoft PSS experience, our recommendation is always: don't
    team. We spend tens of thousands of hours a year troubleshooting issues that
    came down to badly written 3rd party teaming drivers. We pull the teams and
    everything works. Had two different calls on it today, as a matter of fact.

    If you still insist, we recommend fault tolerance without load-balancing (so
    simply recovery from total NIC failure), as the odds of you actually
    saturating a single gigabit on one server is pretty much nil. In fact,
    saturating 100Mbit on one node is highly unlikely. And since they are dual
    NIC's on the same card, most failures that scrap one of the two interfaces
    will likely take out the other since it the whole board usually fails, so
    even the tolerance is often not helpful.

    If you want to go with the scenario below, always run the absolute latest
    NIC drivers and keep them up to date at all times - check with the vendor
    monthly.

    Many thanks, thats sound advice, I know this isn't strictly the forum for
    this query

    Out of curriosity, have you come accross any DFS scenarios using Switch Load
    Balancing (SLB) or would the same advice apply? (it's only something we're
    looking at for the moment)
