Depends on what you're running.

I must refute this calumny.
ZFS likes RAM and will use it to the extent possible. It can be
ordered to use a specific (maximum) amount. Deduplication
requires lots of RAM, but hardly anybody actually wants ZFS's
deduplication.
On the nearest server to hand, ZFS is currently using about 2GB
of RAM to support 10TB of available disk space.
