I have 11th gen 11600k and currently two HBA cards 2x9211. I don’t really know much about PCIE lanes. I want to upgrade one HBA from the 9211-8 to a LSI 9300 16i and keep one of the 9211 for a total of 24 drive capability.

 

I’d also like to add the intel arc a380. I know everyone will ask why, because it’s great for me and I’ve had it for a while. I like the AV1 comparability and higher hw transcoding quality. 
 

I don’t know much about PCIe lanes but can an 11th gen lga 1200 board handle a LSI 9300-16i, LSI 9211, and ARC a380? (Also I currently have 3 ssd if it matters).

Not without one more being downgraded.

With one more what being downgraded?  Will it work or not?

One or more being downgraded, LSI controllers will work with an x4 link, with downgraded performance, can't comment on the GPU, probably also works degraded.

The 9211-8 is PCI-E 2.0 so each PCI-E lane can support 2 HDD or 2 SATA SSD at full speed.

You need at least a PCI-E x4 electrical to avoid the array slowing down during parity checks/ drive recovery etc. when all drives need to be read.

 

I expect this is a Z590 board with x8 x8 x4 electrical for GPU, 9300-16i, LSI 9211

As well as the electical, the card has to fit into the slot, the LSI 9211 is physically a x8 card so you either need the x4 electrical slot to be physically a x8 / x16 or on some PCI-E slots, the back is notched so you can plug a longer card and it just connects the first 4 lanes.

Let's try a third time around.  Will it work, or no? If I plug the arc and two cards in will everything function or will it not. Why what when or whatever else doesn't answer the yes or no. 

You never mentioned what mobo, so can't know.

Check its manual, if it has 3 slots that can fit the desired cards and there's nothing against having them populated at the same time as well as the NVMe slots then it'll technically work. Whether everything works at optimal performance is another story and is what people were commenting about, it's likely it won't be the case.

I’m shopping motherboards. Z590 Asus prime has 3 full size PCIE slots but the cpu is an 11600k. 

So x8, x4, x4 from the CPU.

Yes they'll all run at the same time, but as mentioned some will be starved.

I'd put the ARC in one of the x4 slots since it can run at PCIe4, x4 will be enough for what it'll be used for. 

One of the 2 other cards will be starved to half of its capabilities and what goes where for optimal performance depends on what drives are used and how they're split between the cards, but what would likely make most sense is the 9300 in the x8 slot so it runs full speed, and the 9211 at half.

I wouldn’t think a spinning disk could even get close to use that amount of bandwidth. Thanks! I’m ordering now.
