RAID-Z improvements and cloud device support

Solaris 11.4 introduced few new ZFS pool versions with interesting new features or enhancements:

# zpool upgrade -v
 38  Xcopy with encryption
 39  Resilver restart enhancements
 40  New deduplication support
 41  Asynchronous dataset destroy
 42  Reguid: ability to change the pool guid
 43  RAID-Z improvements and cloud device support
 44  Device removal

The RAID-Z improvements mean that data is written more efficiently - in some cases it can now store more data in a pool than before. But even more importantly the performance (both throughput and IOPS) of RAIDZ is now close to RAID10!

What is "cloud device support"?
