I was planning on making an atom board a file server for my home, and I have two options: soekris net6501 2GB RAM and intel board powered by the 330 atom (says 2GB limited as well). My plans are
to use from 4 up to 8 disks, and they should be 2TB at least.

As its for home use, some p2p software and mostly music listening and sometimes movie streaming.

should 2GB be that bad, that I should drop it and use UFS instead ?

I may run any version of FreeBSD on it, was planning on 9-STABLE or 9.1.

In the same time I have a couple of hosts successfully running zfs on 768 Megs and on 1 Gig of RAM. Both i386. And they aren't affected by the periodic weekly for some reason. And they are used only as fileservers.

So when I see all these advices to add a gazillion gigabytes of RAM to use zfs - I don't see the connection.

The connection is performance and/or lack of tuning.

At home I haven't a problem to run a system with ZFS and 768MB and 1GB (well, the 1GB system has hardware problems, so it is degraded to a toybox to test things now, but ZFS is still rock solid on it). At a place where more than a handfull of people would access such a system in a way where the performance of big file transfers matter (not streaming, not just watching a movie on one system, ...), I would also recommend more RAM.

Bye,
Alexander.
