    I am re-organizing my company's network, albeit a small one, but it is still
    very very important.
    I run a small webhosting company, and I am rebuilding the LAN with the idea
    of expandibility.
    the LAN Diagram is here
    http://www.bluhayz.org/~dero/overall_lan.png
    (I apologize for PNG, but that's how AppleWorks wanted to save it.)

    Anyways, I am wondering about overall network performance, given that our net
    connection isn't higher than 45Mbps (burstable connection, yay!)

    (All machines are running FreeBSD 4.8-RELEASE)

    The plan is to store all user directories, i.e. web sites, on the NFS disk
    server, equipped with a gazillion disk drives, all with RAID0+1, and simply
    running NFS (and of course SSH)
    Then the FTP server(1), the web servers(2 at current point in time) and then
    somewhere in the future, the MySQL servers will all have data stored on the
    NFS server. In addition, the overall workload will be spread across the web
    servers, using BIND's round-robin capability.
    Note: I am planning on upgrading to Gigabit sometime soon.

    The question being, how will this network perform, I realize there will be
    increased network traffic, but the two things I am worried about, are overall
    added latency, and plausibility, i.e. before I buy more hardware, will this
    work!
    The biggest toss-up is the tradeoff between a couple ms of latency, and
    expandibility. According to this current diagram, all we need to do to add a
    new server to help releive load is to add a new Web Server, and configure it
    in the BIND configuration files, and get it to use the NFS server.

    Help is not only needed, but appreciated.

    thanks!
