FreeNAS 0.7: powerful and not dead

Parent article: FreeNAS 0.7: powerful and not dead

The way I look at it by the time CoreNAS gets off the ground and is ready to
be used, then so will BTRFS. Which will effectively render the whole 'ZFS'
thing mute.

Also, I wonder how well ZFS works with just 128MB of RAM. I know that Sun
says not to use ZFS on systems with less then 1GB of RAM and recommends
64bit architecture for best results. Does anybody here have experience
trying to get a couple TB worth of ZFS storage on a low-end machine?

No, and would be interested in seeing it. However a baseline node configuration of >1G memory seems reasonable for such a product, today.

I'd imagine that you can't use ZFS on such a machine; hopefully FreeNAS's menus warn you or forbid you from trying.

BtrFS is still far behind ZFS in terms of both features and stability, but I really hope that it will catch up one day. When it supports Raid-Z/Z2, file/block deduplication and having a fast SSD LFU-cache that always holds the most used blocks, I will switch in an instant.

Well most those things are the point behind Btrfs.

It's raid features:

Dedupe is being talked about as far as I know and is a goal of the project,
and it has optimized mode for working with SSD. So on and so forth.

Btrfs is still about a year away, I figure. And when you make a major change
to a project, like going from FreeBSD to Debian for CoreNAS stuff, it's
going to take at a minimum several months to create a working product and
that is why I figure that it's likely that by the time CoreNAS is out the
door Btrfs will be in a usable state.

128MB of RAM is an absurdly low amount for a NAS server. You might as well run a webserver on an Apple IIgs while you're at it. Performance will be terrible regardless of filesystem type, since you can't take advantage of prefetching and caching.

My Netgear ReadyNAS (Linux/SPARC) has 1GB of RAM and it's over a year old. Surely the hardware available now has more than 128MB of RAM.

Although, I do agree with your sentiment, I'll see you're ][gs and raise you a ][e.

The CoreNAS website seems to be available now and filling up with info:
