The Blackbird and Lite motherboard only have 2 PCIe slots and the full motherboard only supports 2 out of 5 slots if a single CPU is fitted.

Furthermore, I read that PCIe bifurcation is not supported on the Blackbird and Lite, so they can't have multiple NVMe SSDs on a single PCIe card.

Does Thunderbolt 3 provide an answer to this problem?

I searched for Thunderbolt in the forum and wiki and couldn't find anything about it.

For example, Thunderbolt 3 can connect multiple SSDs, 4k displays and 10GbE NICs, reducing the number of things that have to go in the two PCIe slots.

Here are a couple of the Thunderbolt 3 cards I found at a local supplier:

Some of the issues that come to mind:

- does the PCI card work at all in non-x86 boards?

- can it boot from an NVMe SSD on Thunderbolt 3?

- does the Linux kernel compiled for ppc64 support Thunderbolt 3 boards like this?

Has anybody tried this already or is anybody in a position to try one of these cards?

One downside of using Thunderbolt 3 is the security risk.  Having storage outside the main PC case is not always a good idea.  Attackers with physical access to a Thunderbolt port may also be able to use the port to scrape the contents of RAM
