CentOS Linux vs. FreeNAS

In any role where you need raw server power, CentOS Linux is extremely well suited. It is extremely stable, and in my experience, probably the most stable of the Linux distros available. It has a very wide base of support from 3rd party sources for additional functionality that do not come already in the CentOS Linux distribution itself. It is not as appropriate for situations that are customer facing or end user facing. For those, I recommend Ubuntu Linux. But for everything server & compute related, I recommend CentOS Linux.

FreeNAS is well suited for most storage serving scenarios, whether it be for an office file server, backup destinations, data replication across the internet, or as backend storage for virtual machines. It can serve various types of clients via a plethora of standard protocols and can easily integrate with existing infrastructure using LDAP authentication and so on. It's pretty simple to use (it helps to have at least a basic understanding of the underlying technologies) and almost maintenance-free. One scenario that springs to mind that it may not be appropriate for (yet) is as S3 storage. However, S3 functionality was added in a recent release and may have improved greatly since then. I'm sure it will eventually work very well for this.

• First of all, CentOS is one of the most secure and stable OSes straits from the box.
• High performance on the average hardware.
• In most of my scenarios—easy and quick deployment.
• Huge KB community that helps to build and support different services on CentOS.
• Versions lifecycle.

• The FreeNAS web interface is modern looking. It makes tasks like provisioning drives into raid volumes easy.
• The ZFS raid option allows you to add in an SSD as a cache drive to increase performance.

• CentOS is not a great desktop platform. Although some would disagree with that statement, I think that CentOS is better suited to life as a server.
• Since CentOS is community-supported some software vendors will not officially support it because it isn't Red Hat.

• Not good for beginners as it requires deep understanding of networking and storage.
• Most of the good and required features are not available in free version.

Again, written documentation is excellent, even on the older versions. The support community is the best. It is comprehensive and I would say that it global because it transcends national boundaries. Also, you find all types of people using CentOS to do all sorts of things so you are bound to find someone to talk to if there are problems.

There were some things that can be found by other users on forums and Google and some things that were not.

CentOS is based on RHEL, so it really came down to the costs when making the selection between our options. RHEL offered more support and features, but nothing that we specifically needed. CentOS is fully customizable, something Windows Server was also lacking in many ways. The stability and speed was unmatched in comparison to Windows, and we were not utilizing any Windows-specific software to require us to use the Microsoft alternative. My years of experience have also made it a breeze to set up and configure new CentOS instances, leading me to stay where I'm comfortable.

FreeNAS effectively uses all resources really well and it is highly recommended for in premises NAS. It has unlimited ROI as it is really free and open-source. The only payment we need to pay is when we need any support from those guys. FreeNAS helps us to effectively do our work with the legacy systems as it manages all the components really well. FreeNAS although rebranded to TrueNAS will still be there until our legacy systems run.

• CentOS's support of RPM packages makes it very easy to replicate RHEL servers for development or testing in cheap / free environments
• CentOS's minimalistic desktop environment requires additional tweaking / packages if you want to have a usable desktop environment with the niceties of other modern distributions. As a result, if developers want to use CentOS, they'll need to spend more time customizing it than other distros.
• CentOS's easy customization from the command line lends itself well to our virtualization infrastructure where setup can be easily scripted to modify CentOS's configuration files.

• Low-Cost Network Attached Storage
• Provides additional network storage to support client & business operations
• FreeNAS secures our data using custom encryption keys
