I've been tasked to find for a solution that will allow me to use 1 storage location for 2 different web servers' applicaiton data. My problem is that these 2 web servers will both be accessing the same files. I need a way to lock the file if 1 server is using the file so it can't be accessed by the other server until the server is done accessing the file. I'm using licensed VMware ESXi 4.1 for my hosts, Windows 2008 r2 web edition with IIS. I have both of these servers hooked into redundant switches going to an iSCSI San. I'm told that I need a 3rd party software that will allow me to do this, because I'll be using ntfs for my SAN Volume that will store the data. This is an active/active configuration.
Does anyone have any idea how I can make this work or what other software I might need to control the file accesss. I'm told that this ability is not suppported natively in Windows 2008 web or IIS.
