    Hmm where is the distance issue? You run fibre to the switch in the same room as the server and use a 2 m fly lead to connect the servers tot eh switch.

    Me?

    Im on about the distance between the switch in the main building and the one in the server building.

    Re: Gigabit Fibre NIC's

    The only problem I see with adding another switch is the fact another switch will decrease the network latency. Would rather basically extend the cables from the server to the backbone (atm copper) to the servers new location (becomming fibre because of distance)?

    Re: Gigabit Fibre NIC's

    So you are saying that your servers currently plug in via gigabit copper? The existing backbone is copper and you convert from copper to fibre in order to send the fibre over to your new building.

    Adding a copper to fibre media converter is adding a new swtich in anyway.

    How many servers do you currently have? how many fibre links do you have to your new building or are intending to put to your new building?

    I would have thought you would be better off plugging your existing copper backbone into a switch in the existing server room.

    Running fibre to your new server room to a new switch and plugging your servers into this with copper gigabit connections.

    With good quality switch gear at each end this will be fine.

    Re: Gigabit Fibre NIC's

    Or just leave all the servers where they are and have a single fibre run to the new build to give you connectivity in there and do all server admin via remote desktop?

    The existing backbone is copper and fibre - we have loads of free fibre ports so no more converters would be used - just plug the servers into to a fibre port instead of a copper port.

    Re: Gigabit Fibre NIC's

    Plust the whole idea is to give a dedicated network management facilty so the servers cannot remain where they are.

    Re: Gigabit Fibre NIC's

    Ok well I think in that case the question of expandability as previously mentioned should be considered.

    If you use multiple fibre links from the a switch in the new building to the existing one then you will have all the bandwidth you require.

    Then plug your servers into this new switch that has been choosen for it's spare ports for future expansion.

    How many fibre links are you proposing to run to the new facility?

    What is your current switch for the copper to fibre connections?

    Re: Gigabit Fibre NIC's

    Right here goes technical specs:

    Backbone Switch: HP Procurve 530XL J4819A
    Fibre Backbone Modules: HP Procurve Mini-GBIC XL Module J4878A
    Fibre/Copper Backbone Module: HP Procurve GIGT/GBIC XL Module J4907A

    As so:



    At the moment the copper connections are to the servers as well as a few other things (a couple of servers are running in through fibre as well). The plan is to buy another Fibre Backbone module (J4878A) and run fibre from the four ports to the four servers that will need to be over in the new facility. The other servers are distributed out throughout the school and are fine where they are i.e. science application server in the science facility.

    Re: Gigabit Fibre NIC's

    Ok, here is how I would go about it.

    New fibre module in the backbone switch.

    New switch in new location with fibre and enough 1000/100 cat5 ports

    Connect the servers using cat5/6 patches.

    Then configure the two switches have a trunk between them composed of the mulitple fibres.

    Then depending on how you lay the fibre, i.e. 2 * 4pair or 1 * 8 pair for example, go with two seperate cables. If one gets cut you don't lose everything.

    This should then give you (depenent on the the amount of fibres) a 2/3/4 gig trunk.
