Non Global zone types

There are Two types Non-Global Zones.

1) Sparse root zone
2) Whole root zone

Sparse root zone:

A Sparse root zone optimizes sharing by implementing read-only loopback filesystems from the global zone and only installing sub-set of the system root packages locally. The majority of the root filesystem is shared from the global zone. Generally this model would require about 100mb of disk space

Whole root zone:

All of the required solaris packages are copied to the zones private filesystem.
