Recently as part of an upgrade I splurged on some new cache drives and a new rack mount case to fit better in my 19" rack than my full size server did. I got one with an 8-bay "hot-swap" backplane. This one to be specific. - https://www.rosewill.com/rosewill-rsv-h408-black-silver/p/9SIA072KNA9804 I have 7 drives and 1 NVMe. This is all running on a ASUS Maximus IX Code motherboard with an intel i7-7700k. I have a A380 card as well. Drives 1-4 - connected to the backplane, SAS HD to 4 SATA splitter into motherboard SATA slots. Shows up fine. Drives 5-7 - connected to the backplane, SAS HD to 4 SATA splitter into PCIe expansion card. None of these show up. I've tried a whole slew of configurations including shuffling around PCIe slots and swapping out cables, moving drives around and for the life of me I can't get all 7 drives to show up.... unless I don't use half of the backplane bays. Connecting power and SATA directly to the drives seems to work. The weird thing is I could move all my working drives (drives 1-4) to the "non-working" side of the backplane and then all those drives will show up like normal. As soon as plug in drives 5-7 into the previously working part of the backplane drives 1-4 no longer show but 5-7 do. I'm absolutely stumped, not sure if anyone has seen this before or could provide some guidance.
