There are definitely people running ZFS on systems with less than 1GB of RAM. I'm not sure if anyone is running ZFS on a system with less than 512 MB of RAM.

(FWIW, at one point the amount of address space was far more important than the amount of RAM -- amd64 systems with 1 GB of RAM would run better than i386 systems with 2 GB. I'm not sure if this is still the case.)
- radiowave 10y agoBack in the days of OpenSolaris, I was absolutely running it on 512MB, including a Gnome 2 desktop. I won't claim it won any records for speed, but it absolutely worked, and the data survived a rather nasty intermittent disk controller failure. No first-hand experience with ZFS on BSD, but I believe in the early days of the ZFS port there were issues where if the system came under sudden memory pressure, ZFS might not hand its RAM back to the kernel fast enough, leading to (I guess) a panic. So this is a fit-and-finish issue with a specific port, not an inherent ZFS issue, but it seems to have fed into the whole notion of "ZFS needs bucketloads of RAM".
