For system administrators, the greatest improvement of Solaris ZFS over traditional file systems is the ease of administration.
Solaris ZFS takes a single command to set up a mirrored storage pool and file system. For example:
# zpool create home mirror c0t1d0 c1t2d0
The preceding command creates a mirrored storage pool named home and a single file system named home. The file system is mounted at /home.
With Solaris ZFS, you can use whole disks instead of partitions to create the storage pool.
You can use the /home file system hierarchy to create any number of file systems beneath /home. For example:
# zfs create home/user1
In addition, Solaris ZFS provides the following administration features:
Backup and restore capabilities
Device management support
Persistent snapshots and cloning features
Quotas that can be set for file systems
RBAC-based access control
Storage pool space reservations for file systems
Support for Solaris systems that have zones installed
