Hi
We have some new hosts with 1.5T memory and this causes a zones/swap
of 1.5T to be created.
Is this necessary in the GZ ? Each VM gets its own swap so just not
sure what would be running in the GZ that would end u using that swap ?
Thanks

Hi Len,
Here's some output for example:
# vmadm list | wc -l
32
# prstat -Z

As can be seen the GZ doesn't need that much swap for itself - someone
correct me if my findings are wrong.
