ZFS does not require gigs of RAM to work, it's ARC that does. You can have ARC disabled, but then ZFS performance isn't that good.

- ryao 12y agoARC would be perfectly happy with small amounts of memory. ZFS ' ARC implementation will free memory as required by the system (provided that the Linux kernel asks) and grow when memory is not in use up to zfs_arc_max. The limit is completely configurable and can be set to something small like 64MB.
