Clustering Win2003 Web Servers and DFS

Posted on 2006-05-16

We are interested in setting up clustering for our web servers using IIS and from previous postings I see that the way Microsoft intended the servers to stay synchronized was to use DFS.  Our web server content change dozens of times each day and we have around 20,000 visitors hits daily.    From previous postings we learned that there is no mechanism to force synchronization, how can we be sure that the content is the same for both?  Can we publish to the virtual ip?  I also read that IISSync can be used, are there any issues with synchronizing the inetpub directories?

    This is tricky, because DFS isn't intended for this one. The sync is intended for a backup and will not sync as fast as you like it to sync.. Normally, web site data is static so you don't have a constant need of syncing.
    My option would be to install two static web server in a NLB clustering (Network Load Balacing) and put the dynamic data on a backend server. If this data is extremely critical, you can always choose to use Windows CLustering with a SAN or NAS and setup an active passive cluster.

    Else, you will need to be looking at 3rd party software and there will still (and always) be that question if syncing really works that fast.. Unfortenately, Windows cannot let two servers connect to 1 data store like a SAN or NAS.
