DNXIQ can be used via PCIe. You need the Blackmagic HIB card in order to use with Z8G4's PCIe.

Here's a little HP Thunderbolt musing.The Avid configuration guide for the HP Z8G4 states (referring to the Artist DNxIO/DNxIQ connection to the Z8): "PCIe preferred as it requires less system over-head due to direct PCIe to PCIe connection between the host CPU and Artist DNxIO.".It further states (referring to the Artist series Thunderbolt connection to the Z8): "Thunderbolt 2 & 3 - higher system over-head, not recommended to share Thunderbolt devices on the same TB bus with DNxIO, DNxIQ, DNxIV, DNxID"I've been using G-Tech Thunderbolt RAIDs with favorable results and would likely continue this with a new Z8G4. If my interpretation of the above is correct, using the Thuderbolt RAIDs would lock me into using PCIe Avid I/O devices for optimal performance.I don't have an issue using PCIe comforted by the Blackmagic Design promotion of Gen 3 PCIe use for "when you need higher speeds than Thunderbolt".However, except for the DNxIQ, the most recent Avid Artist I/O devices are Thunderbolt only, and I'm wondering if future Artist and BMD I/O's will also be Thunderbolt only. It looks like the DNxIO EOL is 3/22/2022, the DNxIQ isn't listed on the EOL list, so an investment in either carries a worthwhile ROI.I can't find any information related to adding a second Thunderbolt card to the Z8, on a separate bus. And, even then, the concern seems to be with the system resources required to integrate the Thunderbolt interface between the workstation and the peripheral device. Makes one wonder why HP did not provision native Thunderbolt support on the motherboard, and will they in the near future, and is it really needed for I/O connectivity when apparently faster PCIe solutions are currently available?As an alternate to Thunderbolt connected RAID, I would be curious to know how well 10Gbit single or dual port Ethernet (non ISIS/NEXIS) external storage performs for those who use it.I welcome any responses.Karl KnowlesTallahassee, FL
