Hello
This is my first post here, hopefully it's right place for this question,
I'm building NAS project with raspberry pi5 + 4x 3.5 SAS/SATA backplane. I'll be using JMB585 chip board and some backplane from big, old server. Connecting drive via backplane is easy, but there is something more that I would like to cover in this build: led lights for drives.
There is IBPI standard for led lights: https://en.wikipedia.org/wiki/Internati ... rpretation
also there is two types of connectors on board: SGPIO ( https://en.wikipedia.org/wiki/SGPIO ) and SMBus.
Usually backplane is connected to supporting board (or/and SAS/SATA/RAID controller) via smbus, which should be some variant of i2c, I guess I need to connect this to i2c lines on pi and try to find address via i2ctools (and force mode). Is there anything I need to change to get SMBus compatibility?
For SGPIO I don't know anything yet, it's also four pin connector for led lights, is this something to pass all led light to some front panel? What can I do about that one? Are there any ready to use panels that can be connected to that header?
