How to calculate the capacity of servers?

Question

Network administration

let's say there is a base how to determine how much power a server (hardware) will need so that it spins there, or a file server, in general, the question is, depending on the need, which server to take and what to look at? I will be grateful for the answers, or maybe links where to read this topic

Answer 1

Of course, you can look at the recommended technical requirements for all technologies used on the server, but I think that in most cases they take the server for a test period (or with a guaranteed margin) and watch its operation, and if necessary, perform load testing

Answer 2

Scientific iterative poke method

Answer 3

You'd better describe your needs: number of users, data volumes, data type and budget restrictions, otherwise you won't get any help.

Answer 4

You could say it's a textbook .

Answer 5

Everyone's needs are different and practice is different.
You take the minimum virtual machine, then look at the monitoring, what is missing, add it.
Take the iron server as much as your budget allows. Even if the capacities are superfluous, there will always be something to load. To assess the needs, you can drive the task on a virtual machine before buying.
