    Do I need an additional server?

    We currently have 3 Domain controllers over 3 servers. All the students work come off 1 of the controllers and in performance manager the disk queueing is most of the time at 100%. This causes the whole network to be really slow, clicking start on any workstation becomes a waiting game.

    My idea is to get another server in, use file replication services and somehow get them working in a way that if 1 machine is being used heavily, then get the students work from the other server...

    Everyone talks about it in books and at conferences and makes it sound easy...

    Is it easy and is it the right thing to do? Whats involved?

    Thanks for all your support, cheers guys

    Re: Do I need an additional server?

    I know it may not be ideal, but what about spreading the home folders over the 3 servers?

    So:
    Server 1 - Y7 / Y8
    Server 2 - Y9 / Y10
    Server 3 - Y11 / STAFF

    That way all home folders aren't utilising space on all servers?
    I dunno, just a thought

    We use the method of just having certain year groups work on certain servers.

    What's not a great idea that we have is one of them is the Exchange Server aswell.

    So how's that work when year's progress? Moving students from 1 place to another then highlighting the users, change the profile and home dir to the new server...

    Seems easily possible... surely someone here has load balancing?

    Re: Do I need an additional server?

    The work stays where it is.

    At the moment we have:

    Server1: 8 and 9 and staff
    Server2: 10 and 11
    Server3: 7 and 12 and 13

    Next year, these will all stay on the same servers as they are, the Year 13s will be removed and the new Year 7 will probably go on Server 3 aswell.

    Whichever server has the least amount of users on at the start of a new school year will get the new year 7s on it.

    Re: Do I need an additional server?

    We've split things up like that. However we use DFS to keep the naming structure uniform. Therefore we have the following servers

    amphion -> student my documents.
    zethus -> staff my documents
    ch05 -> subject areas
    ch04 -> applications

    When exported out via DFS it ends up looking like this:

    \\carrhill\shares\year7\
    .....
    \\carrhill\shares\year13\
    \\carrhill\shares\staff\
    \\carrhill\shares\subject areas\
    \\carrhill\shares\apps\

    You can use these DFS generated UNC names anywhere.

    How do you enlist the help of this chain of Sofa shops to do this? Sounds helpful.

    It means I wouldn't need to have a list on my wall then saying which users work is on which server?

    DFS is nicer to use with an R2 server as well.

    No you don't. Plus it means if you have replace or move servers around you can do so without upsetting the names everything else is using.

    A word of warning though, don't bother attempting to do any replication with DFS, it doesn't work reliably.
