Thanks for the Summary
Two quick notes.
1. Paul Dagnelie from Klara systems was looking for Interest and
funding to Port OpenZFS features back to illumos.
If you do not want Illumos ZFS to be a dead end, either integration of
important OpenZFS features in Illumos or a full switch/re-merge of
Illumos ZFS with OpenZFS seems inevitable for me. (The OpenZFS user
discussions around a possible OpenZFS LTS shows that the Illumos
stability aspect is a concern there too but Illumos as sort of OpenZFS
bloody/LTS similar to OmniOS is propably out of resource capabilities).
I would prefer a re-merge helping to concentrate on unique
Solaris/Illumos aspects like the in many ways superiour (over SAMBA) SMB
server or Comstar and similar Solaris goodies.
Both methods are not easy as you see in Qnap ZFS that is a "freeze" of a
2019 OpenZFS without newer features ported since. This is ok for now but
not helpful for the next years, looking at whats on the OpenZFS agenda.
2. Do you know if Zettalane is sponsoring some work as stakeholder or
is interested in doing so? Either with OmniOS Assiciation or intersted
in funding with the new Association?
I do not know.
I would hope, they help to improve Illumos ZFS and not only use it.

*Highlights from yesterday's OpenZFS developer conference:*
*Most important OpenZFS announcement: AnyRaid*
This is a new vdev type based on mirror or Raid-Zn to build a vdev
from disks of any size where datablocks are striped in tiles (1/64 of
smallest disk or 16G). Largest disk can be 1024x of smallest with
maximum of 256 disks per vdev. AnyRaid Vdevs can expand, shrink and
auto rebalance on shrink or expand.
Basically the way Raid-Z should have be from the beginning and
propably the most superiour flexible raid concept on the market.
*Large Sector/ Labels
*Large format NVMe require them
Improve S3 backed pools efficiency
*Blockpointer V2
*More uberblocks to improve recoverability of pools
*Amazon FSx*
fully managed OpenZFS storage as a service
*Zettalane storage*
with HA in mind, based on S3 object storage
This is nice as they use Illumos as base
*Storage grow (be prepared)*
no end in sight (AI needs)
cost: hd=1x, SSD=6x
*Discussions:*
mainly around realtime replication, cluster options with ZFS, HA and
multipath and object storage integration
*already in current OpenZFS (and sadly not in Illumos ZFS)
*Draid (for very large vdevs, massively improves resilver time)
Fast Dedup (improves dedup)
Special Vdev has slog and dedup vdev functionality (perfect for
hybrid pools)
vdev rewrite (rebalance, reorganize vdevs)
direct io (improves NVMe pools)
