We performed a comparison between Cisco Nexus and VMware NSX based on real PeerSpot user reviews.
Find out in this report how the two LAN Switching solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."This solution improves network speed and provides high availability for our users."
"The scalability of the solution is well beyond anything I would ever need."
"The most valuable feature of this solution is its reliability."
"Its easy management is most valuable. It is easy to use, easy to manage, stable, and very reliable."
"The most valuable feature of this solution is its stability."
"The most valuable features are the access layer security, OpenConfig, and OpenFlow."
"This solution streamlines how we have to configure things because we can do everything from one device, whereas if we had individual devices we would have to go to each one and configure them manually."
"The most valuable feature of this solution is stability. We have a pretty large campus."
"Has a great firewall."
"It operates on a logical level, providing a comprehensive and centralized way to manage your network resources."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
"VMware NSX offers some of the best features for security, such as micro-segmentation."
"NSX extends Layer-2 scalability on Layer 3, covering the vRO and extending the capability on Layer 3 by decapsulating using a new mechanism. NSX-V was designed to use with VMware products and Success 360, providing more flexibility toward different levels of cloud, containers, and components. NSX-T gives you the ability to stretch your network across different view locations. If you have multiple sites, you can connect them using NSX-T."
"Overall, for me, it's a good solution and has been working well."
"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."
"Overall, I would say the solution has been quite stable."
"The initial setup was somewhat complex."
"In the Nexus 3500, you can't do per-port Jumbo frames, so you have to enable it as a global configuration."
"Stability is not really up to the mark."
"One of the biggest challenges, which I see is that there's a constant evolution in the product. For example, our configuration is based on what is known as traditional data center implementation. Today there is the ACI deployment and to implement, to migrate from one technology to another, that's challenging both from a configuration perspective and also from a cost perspective."
"We lag on the configuration. The changes make a difference in troubleshooting."
"The only issue that I have with this product is finding help on different commands when I'm trying to make a change."
"Nothing is perfect."
"It would be nice if the solution offered multiple types of port support."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"VMware NSX should be able to scale for different customers, even the big ones. Its scalability needs improvement. Stability for it should also be improved."
"It needs to be cheaper."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"Its licensing model could be VM based."
"Lacks integration with other solutions."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
