Arista Extensible Operating System (EOS) vs. Oracle Solaris

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.

It's good for environments that need to operate 24/7 due to its stability, as I mentioned before. It's also very good for enterprise applications that can't afford unscheduled downtime, for truly high-priority environments. I don't think it would be recommended for small companies with people who have no prior knowledge of the tool, as the learning curve is quite steep.

• 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.

• Preferred Operating System to run Oracle Databases
• Performs well with Java and Oracle applications
• Great for Virtualizations.

• 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.

• It seems that Solaris is becoming an afterthought at Oracle.
• Oracle should be more vocal in their commitment to Solaris
• Support Costs

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

You need to take the time to learn it. It is a massive product.

The support teams are well trained and responsive. Patches are rolled out regularly and are easy to deploy and backout.

Stress testing and timing is key. You need test systems that mirror the live environments. User testing must be reflected in peak loads.

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.

We used Windows Server quite a bit because of the ease of use for the team, file sharing, Active Directory, and systems integrated with Windows; learning was easier, and the interface was more user-friendly. On the other hand, Oracle stood out for its stability because we provide services that keep environments up and running 24/7.

• 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.

• Possibility to migrate old servers protecting previous inversions
• reduces implementation times and accelerates time to obtain value in the market.
