Multiple swap spaces after refresh Solaris 11.3 install on Sparc T5-2

Hi
The following is the output of "df -h" and "zfs list" right after fresh installation of Solaris 11.3 on Sparc T5-2 with 256GB memory. Because the server has 256GB of memory, I think Solaris created swap file system mounted on /system/volatile and /tmp, but my question is, zfs also has zpool/swap with 4G which is not much compared to the memory, do I really need this 4G swap space under zpool?
Thanks

Code:

root@solaris:/#  df -h
