You will need a whole lot more information than that in order to do
capacity planning.
Here are a few questions to get you started
-What is the expected percentage of read vs write transactions.
-Are they small OLTP style writes, or larger ones?
-Do you expect these transactions to be equally distributed over the
day, or do you expect bursts?
-Are you going to be dealing with highly concurrent access, or is it
distributed?
-what is the expected cache hit ratio?
-what is the expected data size? What is the expected growth rate?
