Create bootable raid for HP Z840 with hp z turbo drive quad pro.

[GON81]

Hello!

I need some help, thanks in advance.

I have an HP Z840, I upgraded with an hp z turbo drive quad pro and installed two Kingston skc3000s1024g 1tb disks.

The plan is to mount a RAID0 and install the bootable operating system there (WIN 11) and change the current 2 SAS disk in RAID1 with the OS for a RAID0 of 2 disks, and use it for storage.

First I installed the OS on a single nvme disk and there was no problem installing and booting from the nvme ssd without problem.

Then I installed a second disk and I did as in the video, and created a single disk in RAID0, from windows disk management (new striped volume), but from the BIOS I still see 2 disks, and when I try to install Win 11, at the end of the installation it gives an error.

After watching a video ( https://www.youtube.com/watch?v=umLcRS05nAk&ab_channel=RACERRRZ ) and reading a bit, I saw that it is advisable to update the BIOS to the latest version (it is now updated from 2.44 to 2.61) and that it is mandatory to configure slot 6 bifurcation to x4x4x4x4.

After doing this, everything remains the same. I have tried to dissolve the RAID0 from disk management, but it does not give me the option to separate the disks to try to recreate the RAID0, now with the correct configuration...

What am I doing wrong? Can you help me?

Thanks for reading this far!

to remove a raid array created using the z840's onboard controller via the z840's bios use the same method to access the z840's onboard SAS/SATA chip through the bios and then select the desired  array then select the shown drives one at a time and then select remove to break/remove the existing raid

the z840 with the latest bios supports bifurcation as i recall this needs to be enabled in the z840's bios on the pci-e x16 slot with the z turbo drive quad pro card installed once this is done the z840 should show  the 2 or 4 ssd's installed on the HP z turbo drive quad pro card

note that unless you have dual cpu's installed the white pci-e slots are non functional

the whitepaper link below may be of use to you as it covers many useful raid topics on the Zx40 series workstations
