This can impact your other work to do on that machine severely.
However, if that is only a fileserver, ZFS will manage to keep
some memory available so that the machine will not swap if
nothing else interferes. Insofar Damians comments on unused
RAM are correct. But if you know you need space for something
else often, see my remedies for this problem in this thread:
