    Gigabit LAN Implementation

    Locked

    by bino’s · about 11 years, 11 months ago

    We have an existing network running on a 10/100 LAN connections 300
    Desktop and 10 Data Servers it is connected on the managed switch
    10/100.

    Here is my questions.

    If we will implement Gigabit on the server side putting a gigabit
    switch connecting all the server on it then it will be then be
    connected on our 10/100 VLAN switch. Will there be any improvements on
    the desktop side connecting to the server considering that the gigabit
    switch of the server is connected to the 10/100 managed switch wherein
    all desktop switch also connected on that 10/100 VLAN switch ?

      If a Gigabit server goes to a Gigabit switch, but then that switch connects to a 10/100 switch for the rest of the clients, then 100Mbps is still your bottleneck to all clients – you probably haven’t accomplished much.

      Depending if your servers really need to talk faster to eachother, in order for response time to a client application to improve, (for example multiple DB servers, or a DB to a front-end web server) it is possible clients on the 10/100 network will see application-specific improvements, but this depends greatly on your application/design.

      If your simply talking about file transfers, then all devices in the network must link at Gigabit to see any improvement.

        Use Etherchannel to the 10/100 switch if you have capacity, or better yet use the uplink ports on the 10/100 (if any exist, you may need to get gbics for them) to increase the tunking capacity. You can have a maximum of 8 in a bundle giving you 8x100M in the channel. The thing to decide then is how you hash into the channel for your load balancing distribution. With the majority being on one side configure source MAC or source MAC/IP might be the best option for you. This will give you improvements to your desktops from the servers.
