(*11*)At this level, we’ve noticed extra Raspberry Pi Community Hooked up Garage (NAS) builds than we will be able to perhaps depend. The platform was once by no means a specifically ideally suited selection for this process because of the reality it might handiest connect with drives over USB, however it was once affordable and simple to paintings with, so other people made the most productive of it. However that each one modified as soon as the Compute Module 4 presented PCIe strengthen to the Raspberry Pi ecosystem.
(*11*)(*1*)(*10*)On the center of this NAS is a purpose-built provider board that [mebs] designed in response to the KiCad information the Raspberry Pi Basis launched for (*4*)their professional CM4 IO Board(*10*). Whilst no longer a lot higher than the CM4 itself, the NAS board breaks out the board’s PCIe, Ethernet, HDMI, and USB. There’s additionally a header for I2C, used essentially for the OLED show however naturally expandable to further sensors or units, and nine GPIO pins for just right measure.
(*11*)In fact, that on my own doesn’t make a NAS. Into that PCIe port is going a four channel SATA controller card, which in flip is attached to the arduous disk drives which are nestled into their respective nodes of the published case. A central fan blows over the electronics on the core, and because of suave design and a couple of cardboard seals(*10*), pulls air over the drives by means of consumption vents revealed into the perimeters.
(*11*)As spectacular as this construct is, no longer everybody will want this stage of efficiency. Should you don’t thoughts being restricted to USB speeds, you’ll three-D print a NAS enclosure for the usual Raspberry Pi.(*10*) Or you might want to all the time repurpose an outdated PC case for those who’d like one thing somewhat extra really extensive(*10*).
