Capacity planning can be divided into disk, cpu and memory planning.
We have a similar HW setup in the test environment. For disk planning
you really have to load data and calculate disk space taken. Other
guessetimates are just guess. E.g if x rows are inserted per day in
real environment and you want to store data for y months, load a
sample data and calculate. Extrapolate for next three years.
For CPU planning we simulate the expected load on the system, monitor
CPU usage. We plan to get 50% average CPU usage max not exceeding 90%.
If on the test load you are getting high CPU, look at application if
it can be further tuned. If not you need more CPU power. Same goes
with memory. If you are getting too much paging and swapping time to
get more memory.
