Xinnor RAID

Anyone experimented with or is using Xinnor RAID for NVMe devices with PVE?

Yes! However, not Opus, which I'm not sure is quite production ready.

We have used Xiraid classic on Proxmox hosts. We were so impressed by the performance we signed up as a Xinnor partner.

Using Xiraid classic and then LVM on top, we're able to get amazing IOPs to the guests, but retain all of the Proxmox tooling (migration, backups, etc).

It's really the only way to get the IOPs available from modern DC NVMe SSDs to the guests without additional hardware (e.g. a GPU for GRAID).

We just finished a new case study with Xinnor about small block disk performance: https://xinnor.io/blog/reperio-case...solution-for-databases-and-data-applications/

The post explains what the entire system can achieve (1M+ 4k random synchronous IOPs), and allows Proxmox users to bifurcate that by using individual virtio disks that gives each virtio disk 20k-40k each.
