Is it possible to have VROC NVME RAID 10 with more than 4 disks?

Hi,

I would possibly just treat this as a feature request, but if anyone has a way to get around it would be much appreciated.

I am on Windows 2019, with 12x Intel P3700 2TB connected to one single CPU (e.g. using all 48x PCI Express lanes). VROC enabled on all 3 PCIE 16x complex root hubs. I am not doing any node level clustering so would like to use RAID 10 on these 12x SSDs.

Unfortunately, the closet I can get is I have to create 3 separate RAID 10 arrays, each with 4 disks in it. Then I use Windows Storage Space or Disk Manager to create a stripe (RAID 0) volume to combine these 3 "blocks" - effectively a RAID 100. And of course, as expected, performance is not linear which means there must be performance loss due to the extra software layer added.

I can create a 12x SSD RAID 0 with VROC, but this 4-disk limit for RAID 10 is disappointing. I tried VROC v7 and the limitation seems still there.

Any suggestions are welcome.

Thanks!

Chris

Hello, @dracocephalum.

Thank you for contacting the Intel Community Support.

For this case, RAID 10 support is as you mentioned, Intel® VROC will support only 4 drives in each RAID 10 created, but I can certainly submit your feedback regarding this. The thread can remain open in case the community is able to provide you other recommendations.
