Server cluster or NLB for FTP serving IPTV

    I have a large storage server containing video files for an IPTV service. I
    want to ruggedise this by having a main and backup FTP server handling the
    file distribution to our content partners. I note that both server cluster
    and NLB can be applied. it seems to me that NLB is the more appropriate
    because while new files are being added to the storage server the rate of
    file transfer outbound is not excessive.

    What I need in practice is to be able to fail an FTP server and see the
    backup maintain a common IP address and take the requests and so mainitain
    the distribution.

    Any comments as to the pros and cons of this?

    I'd like to verify whether 2 Win2003 servers running individual FTP servers
    (and acessing a common directly attached storage device) can be protected by
    NLB. I've had discussions with a large vendor about this and they say that
    NLB will not work with FTP. They say only windows clustering will handle this.

    What I need is an active FTP server that serves off the storage server. if
    this fails the passive FTP server takes over and provides access to the
    storage server. I appreciate we will lose the current connection during
    failover, and that I may need Win2003 enterprise edition.

    Does anyone have the final say on this?

  4. NTFS is a "one host only" FileSystem, unless you use some sort of different
    software/filesystem, it is not allowed to have more than 1 host accessing an
    NTFS volume on a direct attached disk.

    Maybe I didn't explain myself very well. I want a main and backup ftp server
    to allow access to a common storage server ( a dell powervault array). One
    server will run the live ftp server with a share to the powervault. Upon
    failure of this server I need a backup server, running an ftp server with
    another share to the powervault to take over and accept new connections.

    So I want to confirm whether Windows NLB or Windows server cluster is best
    for arranging the protection.

  7. FTP is not really a fully support configuration options. IIS/FTP is made for
    NLB. You will need to configure NLB to use 1 node and only 1 node, then
    failover to other node if needed, this is called priority based NLB.

    So would server clustering for IIS/FTP be a practical option. I ask because
    the large vendor is pushing this option.

  10. Kipper,

    Rodney is correct,
    No Server Clustering for FTP/IIS, use NLB (as per Rodney's post)
