Before someone cries hacker, this will be used for client onsite pen testing password and hash encryption audits.

I am asking the question here since I'm wondering if I can use an akitio thunder 3 to act as a bridge- sort of pcie-to-thunderbolt 3 connection to laptops. This chassis connects to a host computer via pci-e.

Why insist on using egpu solution? The plan is to have my team connect their respective thunderbolt enabled laptops on as needed basis.

The Thunder3 can provide you a electrical x4 3.0 PCIe slot into which you attach the Netstor NA260A. The Netstor unit has a PCIe bridge on there that then provide four x8 3.0 slots to attach eGPUs to. This bridged mechanism akin to how a Sonnet Echo Express III-D works. It farms off the TB2/TB3 link up to 3 slots.

In practice there’s the question of how will the TI82-based Thunder3 deal with the Netstor comms?  TI82 enclosures refuse to detect eGPU devices unless they are certified, whereas TI83 enclosures have firmware to circumvent that. REF: https://egpu.io/external-gpu-buyers-guide-2017/#tb3-enclosures

Thanks for bringing this up. I will consider another alternative.

Note: I've spent several hours trying to get an MSI GTS80 to recognize thunderbolt 3 devices, even though the akitio has been certified. I had to update both the Akitio and the laptop's thunderbolt firmware in order for the two to recognize each other.

Where do I look up the GTS80 thunderbolt controller id (to determine whether it has TI82 or TI83)?

Dumb question: Can I use the Akitio (Node) for this purpose since it has a TI83 controller?

Akitio thunder3 uses a TI82 and it is not sure it can manage a Netstor comms device because TI82 enclosures refuse to detect eGPU devices  unless they are certified.

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts

Oops sorry. I meant can I use the Akitio Node (not the thunder 3- man, I hate these closely named products!) 

Yes I understand the Thunder 3 has the TI82. I do have an Akitio Node, which has the TI83.

Another option: the netstor has two extra single width pcie slots. Does anyone know of Thunderbolt 3 pcie card that can go in the slot?

So basically, turn the netstor into a 4-slot Thunderbolt eGPU. Unfortunately, I have yet to see a universal Thunderbolt 3 pcie adapter.

You can ask it to akitio customer service.

Thanks! I just did! 🙂

Update: according to the rep, the node will accept/recognize pcie cards other than just GPUs.

"Yes, you can also install and use PCIe cards other than graphics cards but the card's driver must be compatible with requirements for Thunderbolt technology (e.g. hot-plug support and recovery from sleep)."

I ordered the netstor anyway. If it doesn't work, I'll either resell it or attach it to a mini-itx pc.

It looks like the sonnet 1 Tb3 edition might work better:

It's TI83!

Interesting note: the case will accommodate half-length, double width cards.

I convinced the seller to go down to $1470 shipped for the Netstor NA260A-R (redundant supply) 4 double-width slot chassis. I will be testing with both the Akitio Node and Akitio Thunder 3 PCIe. If this setup works, maybe I'll get a Sonnet Expressbox SEL TB3 edition, which is closer to size of an oversized power brick.

In a demented twist of fate, I also won a CUBIX 4-slot pcie expansion chassis on eBay auction for $565 shipped. The catch is I can only install 2 double width or 4 single width cards. Still not a bad deal for the price.

No go on the Netstor   🙁

I did check with the Akitio representative beforehand and he mentioned either the Node or the Thunder 3 should be able detect the pci-to-host card as if it was installed in a PC motherboard.

 Oh well, hopefully the Cubix will work. It should arrive Monday.
