We are using ECC 6.0 on Windows 2003 with Oracle 10g on HP Proliant Hardware with 32GB of Ram and around 400 user accessing the Server from Different Country. We have new requirement for Access so finally we are thinking to set up a Web Dispatcher so that we can provide the Access of SAP through Web Browser. My question is how to calculate the Hardware size for Web Dispatcher. There is nothing on the Installation Guide. It would be great help if anyone share his idea on this.
