CentOS Linux vs. FreeNAS

I have been a CentOS user for over 10 years and remain loyal to the core OS. When it comes to stability and speed, there's no other OS I'd recommend over it. I base this recommendation on my personal experience, as I have multiple development and production servers running the CentOS software today. It's running on newer and older hardware with ease, and the price is right!

FreeNAS suited really well in managing our legacy systems and it handled all our network flows really well, less maintenance is required on our part. FreeNAS also gave the option to switch to TrueNAS for free as now its support is limited. The major issue that we faced was with the installation as it is really complex and required lots of time. Rest all is good and FreeNAS still works well on our systems.

• 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.

Incentivized

• It's not as intuitive as it could be
• Some packages can be quite old compared with other distributions
• Breaking changes appear often when packages are obsoleted usually with no supported transition path (this is a general *NIX problem, but it's more accentuated in CentOS)

Incentivized

• 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.

Ubuntu Linux is another candidate that we've evaluated. It stacks up well against CentOS Linux, however it does have some quirks we need to deal with such as package management and stability. For the most part, the server version of Ubuntu is stable, but we stick with CentOS Linux because it seems to have a slight edge over Ubuntu in that realm as well. I have colleagues at other firms that are wholesale Ubuntu server infrastructure, and they are very happy with it and Ubuntu is favorable there. With the changes that have occurred or may still yet occur at CentOS Linux, we may go down the path towards Ubuntu. But for now, CentOS Linux is where we are parked and will remain for the foreseeable future.

Before swapping to FreeNAS, we'd been using plan old Linux servers running Samba and NFS with ZFS storage underneath. This worked really well for our requirements at the time but required a lot of administration when new versions came along, or new users had to be added or drives needed replacing, and so on. FreeNAS did away with 95% of that work and does a much better job too.

Incentivized

• Since CentOS is free, our developers and engineers can use it without regard for dipping into project budgets.
• We can spin up a CentOS VM, use it and then destroy it without having to worry about licensing headaches.
• CentOS can run on just about any hardware platform: server, laptop, old hardware, etc. so that makes it less expensive in that we don't have to buy specialized hardware for it.

Incentivized

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