ZFS 2.3.0 deduplication and nvme benefits available?

[intel]

Hi, does StarWind vSAN Free come with ZFS 2.3.0 which included many improvements in deduplication with `fastdedup` and nvme skipping l2arc?

I would like to test vSAN and compare it to native proxmox using the same file system version, there already is a way to get zfs 2.3.1 in proxmox: https://forum.proxmox.com/threads/zfs-2 ... le.160639/

For now, VSAN runs an older ZFS version that hasn't been updated for a while, as we are more focused on newer NVMe-oF solutions. We plan to update to the latest ZFS on Linux later this year, Q2-Q3.

thanks for the reply.

> newer NVMe-oF solutions

Which filesystem do these NVME-oF solutions employ? I thought NVME-oF is more about a transmission protocol than the underlying filesystem but this is the first i hear of it. so curious

NVMe-oF is the protocol, you are right.
To maximize performance, NVMe-oF-connected devices are put on RAW, unformatted disks.
p.s. Join our public NVMe-oF target beta (submit your request here https://www.starwindsoftware.com/support-form).

ZFS continues to support block-level deduplication in version 2.3.0. However, it’s still resource-intensive and not recommended for all workloads.

Good point
