The world’s number one open-source operating system, TrueNAS brings the performance and features of the legendary OpenZFS file system in an easy to use package. Available in two free and open-source software versions, TrueNAS also comes as a professionally-supported Enterprise solution when coupled with iXsystems branded hardware.
We could write volumes about all the benefits of TrueNAS and why it should be in your workplace. For the sake of brevity, however, we’ve narrowed it down to ten things your CIO should know about TrueNAS before deciding on a storage solution. 1. It’s Both a SAN and a...
NOTE: This is historical content that may contain outdated information. The ZFS file system provides data integrity features for storage drives using its Copy On Write (CoW) technology and improved RAID, but these features have been limited to storage drives...
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...
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-grade, open source file system. Unfortunately, the file systems used by other vendors and projects rarely...
One of the more beneficial features of the ZFS filesystem is the way it allows for tiered caching of data through the use of memory, read and write caches. By optimizing memory in conjunction with high speed SSD drives, significant performance gains can be achieved...
The TrueNAS Unified Storage appliance provides a centralized storage repository for all your data, allowing for great savings in the total disk space required and making management simple. Having all your information in one place offers many advantages, but you are...
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...
We are pleased to announce that industry analyst firm DCIG just gave the TrueNAS Z20 and TrueNAS Z30 an “Excellent” rating in their 2015-2016 Midsize Enterprise Storage Array Buyer’s Guide. This is an outstanding testament to the growing recognition that TrueNAS is...
I am often asked if the two storage controllers in a TrueNAS high availability configuration are active/active or active/passive. They’re neither. They’re “active/standby.” Allow me to explain the difference. In the case of an active/passive and active/standby disk...
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.
