Having trouble with shared disk and IIS servers

Good Day All;

 

 

Please excuse what will probably be a dumb question, but I am having trouble figuring out the concept of shared data between IIS servers load balanced by an F5 device.

 

 

We are going to be moving our online application from a single IIS server front end (SQL back end) to a load balanced solution using 2 IIS servers and an F5 box. Our application currently writes documents, and allows users to upload pictures.

 

 

What I'm having trouble with is how will this work in a load balanced environment? How do I deal with writing data that will need to be accessible from all servers in my farm? We will be using a SAN if this complicates things or gives me a few more outs.

 

 

Thank you for your time.

 

  • Hi

     

    This will work in a load balanced environment perfectly. You will need to create a file server clustered i.e. configure 2 servers in the SAN in cluster and point all your IIS home directories to this file server, may be you will need to configure delegation.

     

     

    In the big-ip side you will need to configure persistence in order to maintain the sessions on the same server.

     

     

    Hope this helps.

    What happens if the files that are written need to be accessed by different users? Should I be looking at syncing folders on the LUNs?

     

     

     

  • That depends on your application,if your web-sites on both servers point to the same file share, the upload for the users will be on the same folders, so there is no need to replicate anything, because the 2 servers will be able to see all files

     

    in the share.
