ZFS Hardware and Software Requirements and Recommendations
Make sure you review the following hardware and software requirements and recommendations before
attempting to use the ZFS software:
A SPARCTM or x86 system that is running the SolarisTM Nevada release, build 27 or later.
The minimum disk size is 128 Mbytes. The minimum amount of disk space required for a storage pool is approximately 64 Mbytes.
Currently, the minimum amount of memory recommended to install a Solaris system is 512 Mbytes. However, for good ZFS performance, at least one Gbyte or more of memory is recommended.
If you create a mirrored disk configuration, multiple controllers are recommended.
