I'm hoping someone can help me. I have a HP Z840 with two 2690v3 CPUs. I have a HP Z Turbo Drive G2 in Slot 1, a Nvidia Quadro K2200 in slot 2, and a Z Turbo Drive Dual Pro in slot 6. The Dual Pro only detects the first drive installed. I have two Intel 660p m.2 drives installed. Each drive is known to be working properly.
Any idea how I can get the Dual Pro to recognize the second drive?

Bwells46,
I use a G1 Z Turbo in a z620 but don't have experience with a dual M.2, so comments will be vague.
The Z Turbo Drive Dual Pro is likely to need 1. a driver and 2. configuration of the bifurcation- the splitting of the single PCIe device to read as two independendent drives. There should be HP instructions for that configuration somewhere in Support as there is for installing the Z Turbo G1. Check that the dual drives on that platform can be used independently and don't have to be RAID 1 or 0.
One other consideration for that configuration is that HP seems particular as to the slots used for the Z Turbo Drives and the installation instruction will probably give only one or two choices. The dual one is about guarnteed to need a PCIe 3.0 x8 slot as each M.2 drive will need PCIE 3.0 x4 for full performance.
I have an unusual setup in the z620 as a dual height GPU (GTX 1070 Ti) covers an important PCIe slot so that when I added the second M.2, a Samsung 970 EVO 500GB NVME, the only choice was to use the 2nd GPU x16 slot.
Sorry I couldn't be more specific. I hope those with experience with dual, birfurcated PCIe M.2 will comment.
I'd be interested to know what you find out.
