Hi Mohiuddin,

As per thumb rule you can go with following allocation 30% DB + 70% SAP application.

During installation take care of this allocation.

For SAP tuning,

You can initially start with following configuration

DIA = 40

BGD = 20

UPD = 2

UPD2 = 4

SPO = 3

Go with default SAP parameters at the initial stage. Later based on usage you can further fine tune the SAP application.
