How to find the Server HW and SW requirements

Hi,

We have to install new ERP 6.0 EHP6 and other CRM 7.0 EHP2 and NW 7.0 EHP3 systems. Previous installation guides for older than these versions directly give the minimum hardware and software requirements for the SAP systems to install. But for these latest versions the installation guide seems to be different and doesnt contain the minimum hardware or software requirements. The master guides suggests to use Quick sizer but I am confused in using the tool. The quick sizer results depending on users or throughput for separate functional area in every SAP product. Our requirement is just to install ERP 6.0 EHP6 system to develop add-ons. So I dont want to specify the ERP functional area like HCM, sales, Financials etc to calculate the requirements (same for CRM, NW etc).

So please suggest the way to calculate the minimum requirements for these new SAP releases to install.

Thanks,

Ajay.
