2. ZFS Distributions
Unlike storage appliances that are based on their own distribution of BSD, Illumos or Linux,
napp-it is a „Nasifier“ for some general-use enterprise operating systems that you can keep up to date like
Based on Solarish
- Oracle Solaris 11.3+ (commercial OS)
- OmniOS (free and stable Solaris fork with a commercial support option)
- OpenIndiana Hipster (unstable but with a desktop option)
Based on Linux
- Ubuntu
- Debian
Linux - support is limited to ZFS management, Autosnap, Autoscrub and AutoJob features
and does not include the advanced features of the Solaris release.
Between ZFS distributions you can move ZFS pools with the follwing restrictions
- From/to Oracle Solaris: Pools must be V28, ZFSv5
- From BSD based systems: Possible with GEOM or with GPT partitions spanning the whole disk
- Beside that: OpenZFS distributions must support same features. No problem with current releases.
What is the preferred napp-it distribution
Napp-it is developed under OmniOS and this is the default distribution:
Without a special reason to select something other, you should use OmniOS with napp-it.
The reasons for OmniOS
- active development with a stable every 6 months
- long term stable editions
- minimal OS, just enough for a fully functional ZFS server for best stability
- free but with a commercial support option
- Just enough ZFS Storage OS, the ZFS server with the smalles footprint, reason of its stability
The reasons for a Solarish based ZFS System
- 100% focus on ZFS that was developed for Solaris 10 years ago and is most stable and complete there
- a complete storage OS from one hand, not the toolbox with a core OS and many options and vendors
- stable support for mirrorred ZFS boot systems with boot environments (restore a former bootable OS state)
- WWN enumeration of disks (disk unique identification) to keeps disk id identical over controller, server or OS
- fault management with active hot-spares that replaces faulted disks automatically
- SMB, NFS and iSCSI integrated in the core OS and maintained by Oracle or Illumos (OmniOS)
- virtual networking with virtual switches and virtual nics with vlan support
- service management SMF with service auto restart
- Solarish CIFS server with NFS4 ACL (more Windows NTFS alike than Posix ACL) and AD support,
Windows SID as extended ZFS attribute (Permissions stay intact after a restore to another AD server),
- ZFS snaps as Windows „previous version“, stable and just working out of the box since years
