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."From a data center implementation, with respect to competition from your data, there isn't really a product recovery for the different tests other than Cisco Nexus. For example, if you take Multi-tenancy for the data center, it's something which, I think, only Cisco has. There are some implementation from HP, but I think it's limited there."
"The most valuable features are the access layer security, OpenConfig, and OpenFlow."
"It has improved our organization because we have aggregated ports, we're able to put multiple agencies on the multiple different interfaces that we have going there. We're able to separate them out with the use of VLANs and whatnot."
"The most valuable feature is that it is high-density, ten-gig."
"The redundancy and the vPC are the most valuable features. We can integrate two switches together for file transfers; that is, we can operate two switches as one. This is because the network can be shared via a vPC trunk, particularly for devices that are not critical for redundancy."
"The most valuable feature of Cisco Nexus is speed compared to what you would get from a Catalyst Series switch."
"We got increased bandwidth, faster performance, and newer software which has improved our organization."
"Its low latency is most valuable. Its performance is good, and it is also very stable."
"The microsegmentation is a good feature. You can segment details, products, or hardware information."
"During our experience, the solution has been stable."
"The alert features are the most valuable."
"To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product."
"Any administrator with basic networking knowledge, in a couple of days, can be in full control of their networking without going through a networking engineer."
"The initial setup was straightforward. You just have to click it and follow the manuals."
"The Distributed firewall is simple to add to the network and rules are easy to implement."
"It's a beneficial tool."
"There is no feature parity between the 9K and the 5K or 7K, which means that it is harder to position the 9K to future proof them."
"I would like to see more on-device programmability, as it seems to be lacking in this platform."
"It would be great if they could make the interface a little more user-friendly, but not trade power off for simplicity."
"The only issue that I have with this product is finding help on different commands when I'm trying to make a change."
"The code quality for this solution has gotten worse and needs improvement."
"Areas in which the solution have room for improvement are the interface, management, and reporting."
"Nexus switches should be able to support network function virtualization (NFV)."
"It would be ideal if there was better integration with various other platforms."
"The solution could benefit from improvements in its pricing and scalability."
"If you're worried that NSX is too complex, I would tell you to take another look. If you compare NSX to a similar solution you might find it to be a bit more complex. Usually, the guy that comes in to implement NSX isn't the network guy and will lack the knowledge for the program. He can lack the knowledge for this program and will therefore think it's complex. You need somebody with network experience."
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"Its licensing model could be VM based."
"I would like to see automation capabilities in the deployment process."
"It lacks full knowledge of physical side of the network topology."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"It was stable for one year, there was no impact. In the last two months, we had two big incidents."
