FreeNAS vs OpenSolaris ZFS Benchmarks

We have received a lot of feedback from members of the IT community since we published our benchmarks comparing OpenSolaris and Nexenta with an off the shelf Promise VTrak M610i. One question we received from several people was about FreeNAS. Several people asked “How does FreeNAS compare to OpenSolaris on the same hardware?” That was an excellent question, and we decided to run some tests to answer that question.

NOTE: This article was written in 2010 using FreeNAS 0.7.1.  We have a new article with much newer benchmarks from 2012 posted about FreeNAS 8.3 at We strongly encourage you to read both this article and the newer article before passing judgement on FreeNAS, because there were significant performance improvements made in FreeNAS in recent versions.

Benchmarks Comparing OpenSolaris, Nexenta, and a Promise VTrak

We ran some benchmarks using IOmeter (running on Windows 2008 R2 on our test blade) to compare OpenSolaris running on our ZFSBuild project hardware, Nexenta running on exactly the same hardware, and a Promise VTrak 610i box. We ran all of the benchmarks over gigabit ethernet.

Here are screenshots of the IOmeter config:

Initial InfiniBand Performance Testing

We’ve gotten the InfiniBand network mostly up and running, and have been doing some performance tests with the included WinOF InfiniBand performance tools. Needless to say the results are nothing less than stunning. This is the fastest transport that we’ve ever had available to us to use in the DataCenter. › Continue reading
