Hi,

For SAP systems, you may have several application servers but you still have a single database.

When the database is overloaded, adding more app servers will not scale anymore.

Yes,only one Database server.(except RAC).

Database is not overload now, how much dialog instances can we install?

Unlimited?

Hi,

Use SAP quick sizer, find the needed SAPS for the required througfhput of 40.000 requests per second and ask your hardware vendor for a hardware configuration.

After this you can configure maybe 1 ABAP instance for each 32 GB of memory or 16 CPU Cores.

Of course this ratio is not mandatory - the instances could be bigger : e.g. 1 ABAP instance for each 24 CPU Cores or 64 GB RAM.... This also depends on the memory consumption of the individual requests.

Regards,

Olivier
