FreeNAS or OpenFiler

Something caught my eye recently.  FreeNAS.  Everybody claims that OpenFiler is a much superior system in terms of performance… but the latest release of FreeNAS supports something called ZFS… and ZFS was something that I had really wanted to look at….

One advantage of ZFS is that well.. it is cheaper in the sense that we no longer need to invest in really expensive RAID cards.  ZFS works best with JBODs.  And somehow.. ZFS sounds fast…. the way they use memory to actively cache the read/writes with their adaptive replacement cache (ARC) sounds more intelligent than the default linux disk caches used by Openfiler… and hey performance ain’t that bad when it can:

FreeNAS does have a very nice graph that shows cpu utilization and network bandwidth. During a large file copy, it topped out at 800 mbits/sec with average of 400 mbit/sec so a 1 GB network card is required to fully utilize its performance.
