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.

The only problem I see is using 8x slots instead of 16x slots for double the storage

Whats the problem?

Each NVMe uses 4 lanes. For each of these x8 slots, they have two NVMes, for a total of 8 lanes.

The x16 slot already has 4x NVMe in it, lol. The other x16 slot has a GPU, which is located in that particular slot due to the lovely 3d-printed fan shroud.

One of the other full-height x8 slots also has a PLX switch, and is loaded with 4 more NVMes.

Does the plx introduce noticeable latency, and does it get hot?

I want to get a few, but I don't really have the airflow you do, so I'm a bit worried.

I have not noticed any issues with it.

And- prior to Jan of this year, I used two of them in an r720xd because it didn't support bifurcation. And- can't say I ran into any issues.

I also, have not checked to see if it was hot either though.
