Proxmox VE 9.1.1 – Windows Server / SQL Server issues

I don't think a single volume created with HW RAID can be repaired using ZFS Scrub. Is that configuration really okay...?

It seems to me like we're losing one of ZFS's major advantages...

> For replicated (mirror, raidz, or draid) devices, ZFS automatically repairs any damage discovered during the scrub.

I already know all the warnings regarding this configuration, but since in most cases the references mentioned are experiments on small home-lab, issues on cheap hardware and so on, I would like to cover this topic in the "enterprise servers" context.

The ZFS documentation got a nice summary with points why not to use ZFS on top of HW raid:
https://openzfs.github.io/openzfs-docs/Performance and Tuning/Hardware.html#hardware-raid-controllers

So its more a decision of reliability vs performance.

But thanks for the detailed benchmarks.

edit : If you are currently using ZFS and not using mirroring with hardware RAID, or if you have no plans to revert to hardware RAID, you can ignore this.

Maybe I explained myself badly, I said that I didn't create the raid1 from the controlled server, but I used proxmox to create the raid1zfs

"host" vcpu type for Win11/Win2025 guests is slower than x86-64-v2-aes/v3 ( best is "max" )
because nested virtualization is often active because of VBS, where other vcpu type prevent nested virt.

Thanks Gabriel, after modifying the CPU as recommended, we noticed some improvements on the transfer rate.
Thank you
