BPN-SAS-846A - Backplane
ASR-72405 - PCM card
Supermicro - X9DRi-LN4+/X9DR3-LN4+ - Mobo
Unraid 6.6.7 - OS
25 8tb drives (one internal)
I asked in another forum but thought I’d ask here too for a second opinion.
When I add my 24th drive to my backplane I start getting a ton of errors from multiple drives in Unraid and the drives get disabled. If I add the drive internally to the MOBO through sata all is well (I have 2 mounted in there now and want to move one back to the 24th slot on my SC846)
Thought it was the cable, switched it and it still happens. Then I got another backplane (same model) and it still happened.
This made me think it was the ASR-7204 but talking to and searching around forums like this one I’m seeing conflicting views.
Some people say an 846A is fine for 8TB drives and I’ve seen comments saying People should use SAS2 backplanes with drives my size.
So I’m here because I wanted to know does this sound like a card or backplane issue? Should I buy a SAS2 backplane? Or should I replace my card with something better?
There are a decent amount of comments on backplanes but I swear finding information about my card is hard as shit.
