But I've also seen sites that recommend 8 GB for ZFS. Has anyone here run it with 2 GB (or less)?
I use ZFS pool (mirror) with 2TB of data on system that has 1 GB RAM, works good.
The minimum for ZFS I would say is 512 MB with ARC limited to 128 MB.
Of course its best to use as much memory as possible with ZFS, 4 GB is optimal minimum, but more then 256 GB RAM is still welcome
