ZFS Pool Version 10

This page describes the feature that is available with the ZFS on-disk format, version 10. This version includes support for the following feature:

• Devices can be added to a storage pool as "cache devices." These devices provide an additional layer of caching between main memory and disk. Using cache devices provides the greatest performance improvement for random read-workloads of mostly static content.

This feature is available in the Solaris Nevada Community Edition, build 78.

The Solaris 10 10/08 release includes ZFS pool version 10, but support for cache devices is not included in this Solaris release.

The related bug for the version 10 change is:
