SAP BW system Memory requirement

Hi,

We have SAP BW system version Business Information Warehouse 3.0B. System has following configuration:

~

CPU : 32

Physical Memory: 67108864 KB

Physical Memory Available: 30654448 KB

Database using Memory: Apprx 20 GB

Database Size: Apprx 5.3 TB

~

We are planning to restore this system to a test server. Test server is having 4 CPU and 8 GB RAM.

Can you please let me know to do a restore, how many CPU and Minumum RAM We require on test server? How to check from current configuration, how much SAP is using memory?

Appreciate your help.

Thanks a ton in advance.

Best Regards,

Basis CK.
