OpenZFS: A Brief Background When ZFS, the “Zettabyte File System”, was first developed by Sun Microsystems for the OpenSolaris project, a standard development path of creating a new version number with each new on-disk format change was the optimal way to go. After...
Category: FreeNAS
The former name of TrueNAS CORE, FreeNAS was the original iXsystems solution for cost-effective ZFS storage.
Docker Done Right
Yes, that is a bold statement. The Docker application containment architecture is all the rage right now and FreeBSD just may prove to be the ultimate Docker platform thanks to its 15+ years of containment experience and the unrivaled OpenZFS file system. As one Twitter user put it, “#docker has now had more security issues […]
How OpenZFS Provides Data Integrity Where Other File Systems Don’t
The most important feature customers expect from a storage array is data integrity protection. This is why we base TrueNAS and FreeNAS on the OpenZFS enterprise, open source file system. Unfortunately, the file systems used by other vendors and projects rarely take...
Why We Use ZFS
One of the key pieces of technology underlying TrueNAS and FreeNAS is the ZFS filesystem. In 2001, developers at Sun Microsystems began work on ZFS and officially released it as part of OpenSolaris in 2005. Three years later, a port of ZFS was released as part of...
FreeNAS in Production
I work as a Network Administrator in a shop where we deploy 60+ ESXi VMs on a half dozen host servers. We heard about FreeNAS from my predecessor who implemented it where he is now employed. My boss asked me to evaluate FreeNAS as it is time to replace one of our existing SANs. I […]
FreeNAS 10 Hackathon
Last week, FreeNAS developers from around the globe arrived for 2 weeks of face-to-face discussions and coding sessions for FreeNAS 10. Yes, Virginia, there will be a FreeNAS 10, divided into a series of planned milestone releases (M2-M5) for those who would like to assist in testing and development, or merely just to follow along […]
We’re Expanding!
As you may know, last year saw an increase in demand for our storage and server products and that demand continues to grow. When we started out, we were just a small group of close-knit people. Over the years, we steadily added more and more talent to our company and before we knew it, we […]

Lies, Damn Lies, and Benchmarks
If you’ve noticed, we don’t publish IOPS or latency numbers for TrueNAS or FreeNAS storage. Now, we realize if you’re comparing storage solutions by looking at brochures and fact sheets, this might be frustrating, but I assure you we don’t do it because we’re hiding anything. In fact, it’s quite the opposite. We do it because it’s in your best interest.
A Complete Guide to FreeNAS Hardware Design, Part IV: Network Notes & Conclusion
Network FreeNAS is a NAS and/or IP-SAN (via iSCSI)…which means everything happens over the network. If you are after performance, you are going to want good switches and server grade network cards. If you are building a home media setup, everything might be happening over wireless, in which case network performance becomes far less […]
