It is well suited in environments that have a low change rate. Once configured, the Arista Extensible Operating System (EOS) is rock solid but changes can be a little cumbersome. The good news is that the learning curve of the Arista Extensible Operating System (EOS) commands is relative short. Many of the commands are similar to other vendors and so expertise in one command set should easily translate to Arista Extensible Operating System (EOS). Our network admins had no problem making the adjustment.
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.

Manage - Arista Extensible Operating System (EOS) is comprehensive enough that all of the commands are present to manage the device and take advantage of all of the unique features.
Scale - A single command set across multiple pieces of hardware allow us to script changes and deploy hardware easily.
Update - Arista Extensible Operating System (EOS) updates happen seamlessly and often don't require rebooting the underlying hardware thanks to it's module-by-module approach.

There are "assumptions" for lack of a better word that are baked into the Arista Extensible Operating System (EOS). While many would be considered best practice, there are others that require a great deal of workarounds for specific environments.
Some details about hardware state are hard to get inside the command structure. There aren't summarized views for many of the more routine queries.
Logging - It is difficult to output logging to a SIEM collector and also let logs remain on the device.

Many of the commands mimic or are identical to vendor commands. This makes the software incredibly easy to learn and use. My one complaint is that sometimes the details and summaries don't include a lot of details so it takes multiple commands to get all the information. Detailed output doesn't always include data included in the summary. This is relatively minor and may just be a personal preference

Cisco IOS is probably a universal standard and one that people usually use in basic network classes. Arista Extensible Operating System (EOS) is so similar to Cisco IOS that the commands to do basic configuration are nearly identical. Arista Extensible Operating System (EOS) includes a lot more detail on reporting but you do have to dig for it. Arista Extensible Operating System (EOS) also allows for much more granular configuration.
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.

No Training Budget Needed - Command set is similar to other vendors and it required no specialized training.
Reduced Downtime - Many Arista Extensible Operating System (EOS) updates can happen without rebooting the underlying hardware meaning that downtime is reduced. This makes EVERYONE happy.
Few Bugs - There are very few bugs in the Arista Extensible Operating System (EOS) production code thanks to great Q/A work by Arista.
