We're looking at setting up a stack of PI's (when the backorder is finally filled). We are looking to run somewhere around 30 of them for a project (plus another 10 with external drives for storage). We're assuming that these will not be overclocked and each one will be running at 100% for 50% of the day.
I understand that it's ideal to run [email protected]
regulated. Browsing the forums and other sites that talk about running multiple PI's seem to run each one on a seperate AC/DC power adapter.
My first throughts are that this is probably the most inefficient way to run several of them as there is some power loss on each of the adapters.
I was thinking of having an engineering friend whip up a simple regulated 200-400w PS, which should be overkill for a stack of 30. The other 10, with USB drives (SSD's) will have thier owe power, but it would be nice to wrap these into a consolidated power supply as well.
Before I do all of this and possibly reinvent the wheel, has anyone approached this problem and do they have a solution?
Is there any other recommendation on how we should approach this?
And yes, I'm aware that my Sun X4150 out powers this entire stack. This is what the user has asked and paid for
