    Utilising 2 network cards In a Server

    We have a new server with 2 1GB network cards and I would like to utilise both of the cards to improve performance, the server will be used to backup up to overnight, and could be transferring over 500GB a night.

    Any ideas what I would need to, I suppose something like load balancing or teaming,

    how would I set it up, walkthrough guides etc, would be much appreciated.

    1) Are they intel cards? If not don't bother (just my personal opinion ).

    2) Do your switches support 802.3ad?

    Teaming

    Hi,

    Yes teaming is the way to go. What make are the NICs? INtel, Broadcom ?

    If its Intel then its very easy to create a team using their Intel ProSet software (now accessible by using the device manager). I would also download and use the latest drivers for your NICs as well as these will have better support for teaming.

    There are various options, the easiest is the network load balancing which will work on any switch, the other are where you need to aggregate the two or more ports together on the switch configuration i.e. PAGP, LACP etc.

    HTH,

    Ash.

    Hi,

    I too was looking into aggregating 2 ports together. I have 2 ports on my Intel Xserve which i would like to aggregate together to improve throughput. I have tried to but then realised that i needed a compatible switch (showing my dumbness now) and so purchased switch that supported aggregated links. I now need a little help on getting the right configuration for this to work its best.

    The switch is a Linksys SWR2048.

    Anyone know this switch at all??

    PS sorry for hijacking the thread.

    Thanks

    Linksys switch

    @HodgeHi,

    Check out the following link and download the User Guide (PDF) and check the chapter 4 (Page 16) for configuring your switch to support link aggregation.

    http://www.linksys.com/servlet/Satel...=6333422279B21

    The link is not for the exact model of your switch but it should point you in the right direction in finding the link aggregation section on their web GUI.

    HTH,

    Ash.

    I think the Broadcom NetXtreme cards are okay as well with TOE functionality.

    As long as they have something as nice as the Proset utilities then I'm sure they will be fine

    Thanks for the replay folks found the teaming options for the Intel cards through device manager,

    But another little scenario we have another server with 2 intel server adapters and 2 broadcom cards, can these all be teamed togeather, the intel software only seems to be able to team the 2 intel nics.

    AFAIK its only within the same make and often model that can be teamed, so you would have to team the 2 Intels and 2 Broadcoms, then use the Server 2003 Load Balancer to balance the load between the 2 team "network cards" that you will then have!

    Do the ports need to be identical?

    i ask as we have a server that was built with a foxconn motherboard. It is strange in that it has one 10/100/1000mb port and a 10/100. I find this quite weird.

    Why would you want that configuration?

    What would be the benefits if you cannot team them up?

    This is a limitation of Windows. Linux, for example, can team any old bunch of cards together.

    I don't see what advantage you will get in speed using 2 cards, wont the hard disk interface be the limiting factor?

    It depends what the server is doing. Some tasks are more disk intensive than others. For example, for a database server or a file server, disk speed is very important. Where as for other servers that do not touch their disks often, for example print/domain controller/web server, bonding network cards can help a lot.

    Yeap, hp Network Configuration Utility really easy to use and from what I have seen just as powerful as the Intel alternative. Works with other brands of network cards to so it would be a good choice if you have an hp branded server.
