I can’t say for sure- but, there is a good chance I might have a problem.

The main picture attached to this post, is a pair of dual bifurcation cards, each with a pair of Samsung PM963 1T enterprise NVMes.

It is going into my r730XD. Which… is getting pretty full. This will fill up the last empty PCIe slots.

But, knock on wood, My r730XD supports bifurcation! LOTS of Bifurcation.

As a result, it now has more HDDs, and NVMes then I can count.

What’s the problem you ask? Well. That is just one of the many servers I have laying around here, all completely filled with NVMe and SATA SSDs…

Figured I would share. Seeing a bunch of SSDs is always a pretty sight.

And- as of two hours ago, my particular lemmy instance was migrated to these new NVMes completely transparently too.

    I’m confused. Why do those cards have a heatsink? I needed a card like that because my motherboard did not support bifurcation. So had to use a splitting card. The cards I know that require bifurcation do not even need a controller or heatsink. They are just wired pretty much directly to the pci-e bus.

      I actually looked up the chip numbers, and its a “splitter”.

      I, don’t know WHY there is a splitter, as a splitter isn’t needed, and these cards are advertised to only work on motherboards supporting bifurcation. However, there is indeed, a splitter.

      The documentation is also, REALLY horribly translated.

      Note: Without pcie splitter function in this host adapter (ASM1182E chip), so motherboard must support PCIe Bifurcation. Otherwise, only one M.2 PCIe SSD will be recognized. If you are not sure PCIe Bifurcation of your motherboard, please consult motherboard munufacture or contact us via amazon message

      Here is the documentation for the chip itself: https://www.asmedia.com.tw/product/213yQcasx8gNAzS4/b7FyQBCxz2URbzg0

      I, am not 100% certain how, where, or why it fits in there. Perhaps, its for link power management? Or something.

      But, I can confirm, these cards DO require bifurcation to be enabled. Without bifurcation, you only see the first drive.
