Comparison of Solaris Volume Manager Configurations to ZFS Configurations

In Oracle Solaris 10 releases, you could create redundant volumes for UFS file systems by using Solaris Volume Manager. Solaris Volume Manager is a traditional volume management product with a layer of volume management and a layer of file system management.

ZFS, available in Oracle Solaris 10 and Oracle Solaris 11 releases, eliminates volume management altogether. Instead of creating virtualized volumes, ZFS aggregates devices into a storage pool. The storage pool describes the physical characteristics of the storage (device layout, data redundancy, and so on) and acts as an arbitrary data store from which file systems can be created. File systems are no longer constrained to individual devices, allowing them to share disk space with all file systems in the pool.

In Oracle Solaris 11, you can easily create a redundant ZFS storage pool in one command. ZFS provides two types of redundant configurations, mirrored pools and RAID-Z pools. RAID-Z configurations have similar features to RAID-5.

ZFS dynamically stripes data across all non-redundant, mirrored, and RAID-Z configurations.
