Factory integrated RAID on motherboard for Z Turbo Drive

[IDF_kiwi]

anyone know how to configure the Factory integrated RAID on motherboard for Z Turbo Drive on a z2 SFF g5 workstation. i have looked in bios and on the uefi bios. I can find the sata integration but not pcie integration.

hp support is unavailable due to covid, so it could be a long wait for them to come back to me.

your post lacks critical details such as do you need bootable raid support or just data (non booting)

also which Z Turbo drive? the dual or the quad or 2 single Z Turbo pci-e cards?

Thanks for the reply.

Boot drive.

Two z turbo 512GB nvme pcie drives 2080 size installed on the two motherboards slots. 

Quick specs and piper say it will work. No vroc header on board that I can see.

I can see the uefi sata raid setup.

as far as i know you can not do a bootable raid using the Z Turbo nvme  pci-e cards unless the bios supports bifurcation

if you want a fast bootable nvme raid it will not be cheap as it will require a late model Raid card that has a boot rom

or high end dual/quad m.2 nvme cards that are designed for bootable raid

your simple m.2 pci-2 carrier cards, have no onboard logic to merge multiple cards into one data stream like the above cards i mentioned can do and the onboard intel raid only works with the motherboards sata ports

you can however use the motherboards onboard SATA ports to create a semi software raid using the bios's built in intel raid bios orom extensions, however you will be limited to the sata buses limit of 530 MBps speed

Thanks again. Hopefully the distributor finds a solution. (update) this datasheet from HP quickspecs has been confirmed as showing incorrect information by HP NZ. Raid will not work on a PCIe / zturbo drive if they contain a boot partition.

so the distributor has been great.

hp support not so much, "follow these documents" one was from 2015 and had no reference to pcie drives, the other was on windows 8.

the workstation product manger from hp, " everyone knows you can"t raid if you have more than two drives in a hp workstation". tried this, still doesn't work.

the technical manger from HP "the raid wont work as it sees the pcie drives as having a boot partition on them".

my feeling at this point is just get the machine out the door. I wont use pcie drives again on a hp workstation config again. The biggest data recovery place in Australasia is seeing 20 failed pcie drives a day, I would prefer redundancy over speed any day.
