Sizing guide for BO Data Services 4.1

Hi,

Is there any sizing guide with SAPS like for CPU and RAM on production server for Data services 4.1 available?  We are in process to implement Data Services 4.1 to extract data from ECC.

Also we want to install both BO-BI Information Platform service and DS 4.0 on the same server.

Would really appreciate if you could help me with some suggestions.

Thank you,
