I have 4 raspberry pi2 and and orange pi R1 as a load balancer all running apache2.
This is powered by a 10 amp 5 volt psu.
How many more pi2 could I add to the cluster before 'only 10 amps
' became an issue?
Would swapping the pi2 out and replacing them with pi3 be advantageous or would a go faster stripe on the case be a better investment?
There is also a 5 port 10/100 hub in the box, which would need swapping for one with more ports.
The networking is 100mbit and my upload to the intarweb is 20mbit fttp with lots more down.
It appears from the limited testing that I have done, that the main current draw is at switch on, when everything boots up together, the rest of the time it is just ticking over, nothing like a serious load has been put on it as yet, I was going to wait until I had a really funny cat photo to drop a link to on the faecbook and see if the cluster needs a fan or anything.
What you think?
Grumpy old man.
