For those of you with a technical bent, there is a new standard around in backplane land called IBPI. It’s a new format for LED function on backplanes. In reality, to my understanding, it’s an extension of the SGPIO standard we’ve been living with for a while.
So there is SGPIO “Standard” and SGPIO “IBPI”. In reality people call it SGPIO and IBPI, but technically they come from the same family – the IBPI pattern just extends the function of the SGPIO basic LED function.
So what does all this matter? Very little if you are directly connecting drives, but if you have a hot-swap backplane in your new server, and the Christmas Tree on the front is doing some weird and wonderful things (ie the leds are going crazy), you might need to change the “Backplane Mode” in the BIOS of our controller.
Plane old Series 6 (6405, 6445 and 6805/6805Q) don’t support IBPI. However the 6805T and 6805TQ, plus all the 7 series controller, support IBPI as well as SGPIO. No, it’s not possible for a RAID card to detect the difference between SGPIO vanilla flavour and SGPIO IBPI, so the user has to do the work. We took a punt, determined that IBPI will become the new next big thing and set that as default on our 7 Series Controllers.
So if your Christmas Tree looks like a server and vice versa, check the backplane mode.
