Cisco NX-OS is probably the best way to build a reliable data center network to prevent downtimes. While other solutions provide only the basic SRv6 architectures for networks, Cisco NX-OS goes an extra mile to help enable Data Center interconnection (DCI) with your WAN to tone down on the network complexity. NX-OS from Cisco would also bring in more flexibility on how you manage your networks and scale more easily.

Ease of use and learning is easier. The documentation for CIsco NX-OS is very good as it was in the market for many years. There are very good case scenarios and wiki pages written by well-experienced experts. These pages will provide quick resolution techniques for the most occurring frequent problems and misconfiguration issues.

This easy solution can be a great help for the big companies on easy multiple data processing and effective networking solutions for the various departments and also generating the real-time data reports with Cisco NX-OS is excellent.

Cisco NX-OS offers excellent capabilities for performance acceleration and easy to manage multiple business network operations and a very secure environment that provides multiple different features and is very easy to get started. Cisco NX-OS offers capabilities on easy use of API which allows effective interaction with the OS and configuration is very easy.

The Cisco Nexus and [Cisco] NX-OS are really well designed for datacenter purposes. It's doing VDC so you can split a single physical box into multiple logical (in cases of multi-customer environments, for instance). The FEX Nexus 2K [is] really easy to configure and to be associated with Nexus 5K and doing high-performance work.

The software NX-OS is a very good IOS developed by Cisco. It is very easy to configure and administrate these NX-OS devices. A lot of improved and high availability HA on the NX-OS. A lot of features and added advantages while we use the devices which have NX-OS. overall we are very happy with the product and we recommend it to all to start using.

Cisco NX-OS is designed to run on data centre switches, and for me the key benefit is the ability to merge Ethernet and fire channel management into a single switch hence reducing cabling and management. However we don't require fibre channel at present so these are just being used for the fact they offer 10GbE on every port, which is still a useful feature in the data centre core.
Given we don't use the fibre channel features, having to learn the difference in commands from iOS is a little frustrating at times.

Cisco NX-OS is an excellent option for a core switch if you need solid resilience. It provides a solid level of security for a core switch as well. If you aren't going to be running multiple connections from wiring closets or VM infrastructure then a less pricey option would be recommended unless you need the port bandwidth. Personally I think the VPC functionality within NX-OS is relatively easy to use and works well.

Due to the separation of features and the ability to enable each feature when you need it, using Cisco NX-OS decreases the processing on the switch and the memory use as well. The switches become more powerful and can handle much more traffic and sessions than normal switches. The ease of commands makes it simple to use.

One of the scenarios is to use in the DC network in the unified fabric, where automation plays a significant role. As NX-OS supports programming languages build in, the automation tasks can be run easily. It is also possible to integrate the DC network with DevOps tools. It is less appropriate to use it in the access switches in the DC.

We use Nexus 3Ks for switching in data centers where we host with 1G and uplink is 10G. This may not be appropriate where we need more host port throughput. NX-OS has a very simple design and CLI to use, but we need to have either reloads or code upgrades to fix the memory leak issues.

It is well suited if you have full-blown Cisco solution deployments across the globe because of its compatibility with other Cisco species or technologies. Also, it has a lot of innovative functionalities that you will not find on other network OS from efficiency to security compliance to routing and management effectiveness. If you are looking for an all-purpose OS, go for it, but if you are just requiring specific services that can be found on other network OS, go for that because Cisco is not cheap.

Cisco NXOS is well-suited to our customers in financial institutions like banks and insurance companies. It gives high availability and supports a high amount of traffic, that's why it is well suited to be the core of banking technology. It is less appropriate for small and medium enterprises because of its cost.
