Thanks Tejas for the response. I already saw a similar document before.
It will be great if you can let me know the difference between "SAP FIORI" under "SAP Business Suite" and "Fiori Front end Server" under "SAP Netweaver"
also, I was looking at http://global12.sap.com/campaigns/benchmark/index.epx for SAP Standard Application Benchmarks and could see 2 tier and 3 tier results but the DELL hardware vendor is given only in 2 tier results. but we are going to have application and DB on different hosts which means it is a 3 tier architecture. in that case, how can we compare our Sizing results with the 2 tier benchmark results!! confusing !! thanks, Shiv
