Looking for non-Miner PCIE Splitter (16x to 2-way 8x / 16x to 4-way 4x)

[XLP]

Hi,

 

my NAS MB only has one pcie 16x slot and I want to run a NIC and other cards at once.

This is how I wanted to spit them:

- 16x

        - 4x 10GBit NIC

        - 4x sata card / riad card

        - 4x m.2

        - 4x (Reserved)

 

So I looked for a 16x to 4-way 4x pcie-splitter, but only found 4x to 4-way 1x and other non-fitting mining splitters.

If you found something helpful, please let me know.

 

Thanks for helping.

I'm not quite sure if something like this exists, also, wouldn't you probably bottleneck your NIC and drives?

[Thermosman]

If you can give up reserved and everything is single slot, this would work

I think 4x is pretty normal for NICs and small raid cards... or isn't it?

I mean such an adapter.

I think the cards will interfere since being laid on their side

cool, comes definitely in consideration (Marked as solution)

I only go form 16x to 4x and this bandwidth is enough for 10GBit networking and stata cards

Dont think so, most of the singleslot cards are designed to be so close next to each other

Also the card has one 8x slot for whatever needs the most bandwidth

[XLP]

Just saw that supermicro card only supports gen 2 and has no additional power connectors that make me worry how the 3 card all get 75 watt as in the spec.

[XLP]

if we left the m.2 out we could get along with a 16x to 2way-8x splitter. Any ideas?

Best I could find

However, not sure it would work anyways, as it would have to support a weird form of pcie bifurcation thats probably only on server motherboards

[XLP]

Found something, but its only gen2.0 too bit its more like what I wanted...

Oops, my fault... Somehow I thought of 10Gbyte instead of 10Gbit...

amfeltec.com is a place to look.  Parts like this aren't cheap.

Hmm looks like they only have 4x or less as input, that would be a huge bottleneck.

Do they also make those 16x to 4-way 4x or 16x to 2-way 8x splitters?

I didn't found a splitter with an input with over 4x lanes...

[tt2468]

While splitting lanes without a PLX is possible, and not actually that hard, I dont think that there is a big enough market for things like this sadly. There exists solutions that use PLX chips to expand the amound of available pcie lanes to a backplane, but they are either pcie gen 2 or overly expensive.

It would get a little convoluted but you could get this:

There referred to as PCIe expansion chassis.  They’re very expensive, it’s a lot cheaper to buy a new motherboard for a tenth the price and complexity.

Not sure why you're digging up 2 year old threads, but I think OP was talking in the same chassis so he was after a bifurcation card
