Goal

Kernel zones differ from other non-global zones in that they are configured with a fixed amount of physical memory which is dedicated for use by the kernel zone

See:  http://docs.oracle.com/cd/E53394_01/html/E54751/gpeaz.html#VLZKZgpecg
...
...
The physical memory assigned to a kernel zone is allocated in its entirety when the zone boots. The memory allocated is for the exclusive use of the kernel zone. Once a kernel zone is booted, all of the memory specified in the capped-memory resource appears to be in use to the host operating system.
...
...

Also, as the name implies, Kernel zones  runs their own kernel and therefore their own ZFS subsystem.

 This Document will explain how to configure and limit the memory used by the zfs ARC in both the global and kernel zones.
