Provides a flexible connection to a server that enables us to easily handle a server when it goes down
Pros and Cons
- "It provides a very flexible connection to a server. When you go into history and the VPC, it provides a very flexible connection from it. Once a server goes down I can instruct it easily. So the network actually keeps quality even if onsite it is down."
- "There is some room for improvement when it comes to the frequency on the network."
What is our primary use case?
How has it helped my organization?
It helps for data servers.
What is most valuable?
It provides a very flexible connection to a server. When you go into history and the VPC, it provides a very flexible connection from it. Once a server goes down I can handle it easily. So the network actually keeps quality even if onsite it is down.
What needs improvement?
There is some room for improvement when it comes to the frequency on the network.

For how long have I used the solution?
We've been using Cisco Nexus 9000 for two months.
What do I think about the stability of the solution?
I don't work in security so I do not deal with this subject. I just make the network available. I think it's probably good. From the networking point of view, we just provide them the network that is going to be Cisco 9000, but they are using the servers. I have not gotten any complaints. We just deployed less than two months ago.
How are customer service and support?
The technical support is very good. I really like the way Cisco handles support. I am building this 9000 network. I had a lot of issues because of the vast complications you find setting up a network. I knew I could get help from Cisco.
Which solution did I use previously and why did I switch?
We switched to 400G. We provide 100G on our network. I needed something which can carry 100, so next time this has that option. That is the reason we went with this partner.
Which other solutions did I evaluate?
As a customer of Cisco, we always have had meetings with them on their new products. We tell them what kind of solution we are looking for and Cisco says for this solution you need this kind of thing.
What other advice do I have?
I would recommend this product. It does not give me any headaches. That is the best thing. There are lots of products, but when you use this, it does not give you any headaches.
It is good because when we went to purchase this, we did not have all the information and knowing that there are a lot of options with all those differences, we had some issues, but it is obvious that this solution is going to do everything that we need. That is fine.

Senior Network Design Engineer at Kent State University
Significantly increased our throughput and added redundancy to our data center
Pros and Cons
- "We leverage Cisco DCNM a lot, which allows us to automate."
- "Our only complaint is about the licensing because it can always be a little more cost-effective."
What is our primary use case?
This solution is used in our data center. It is our layer-two switches that connect all of our servers to the data center firewall. Our data center is a little bit different than most in that we're only layer-two in the data center.
How has it helped my organization?
We have increased the throughput of our datacenter. Where before we had switches that were two, one-gig LAG uplinks, we now have eighty-gig. This means that the underlying, layer-two network is not going to be the bottleneck of our data center anymore. It's going to be the other peripherals like our F5 and our Palo Alto that need to be upgraded to provide more throughput.
What is most valuable?
We leverage Cisco DCNM a lot, which allows us to automate. We're working toward allowing the server administrators to configure their own ports for their new servers that they're spinning up in the data center.
What needs improvement?
Our only complaint is about the licensing because it can always be a little more cost-effective.
What do I think about the scalability of the solution?
The scalability of this solution is great. We couldn't afford to buy the ASIC solution, so we bought the Nexus 9Ks and put them in a Spine-and-Leaf topology. We then made each of the leaves their own vPC peers as well, so it allows us to have redundancy between servers.
How are customer service and technical support?
Our local Cisco engineer was amazing during the whole process. He assisted us many times when installing and configuring the system. He also gave us advice on DCNM and how to set it up.
We've opened one tech case where we had to replace a switch because we believed there was a port that was bad. We had the new switch within one business day, so technical support has been awesome.
Which solution did I use previously and why did I switch?
We had Cisco switches in our data center that were reaching their end-of-life in a few years. We also had other vendor switches that were coming up on end-of-life, and we as a team, with our manager, decided that we wanted a one-vendor solution. It would make troubleshooting a lot easier because we wouldn't be opening up multiple tech cases to solve problems. Cisco provided the best solution for us.
How was the initial setup?
The initial setup of this solution was only complex because we didn't have Nexus switches in our data center. We had a multi-vendor data center and the Cisco switches that we did have in there were the Catalyst series. So, it was only complex for us because we were learning a new platform. After we got through the learning phase, it was very simple and easy to set up.
What about the implementation team?
We handled the implementation in-house and asked our local Cisco engineer for help when needed.
What's my experience with pricing, setup cost, and licensing?
We have a three-year subscription for our licensing fees. For us, this product is perfect for what we need and it came at the perfect price point.
Which other solutions did I evaluate?
Arista and Juniper were both on the shortlist. We bought a few Juniper QFX series switches, and we did not like the product at all. We were investigating Arista, but Cisco came in with an awesome pricing plan for us, and a data center solution that met our needs. It was a lot cheaper than Arista, which is why our manager went with that selection.
What other advice do I have?
This product has absolutely surpassed our expectation of throughput. The network team used to be blamed for slowness in the data center, but now we can confidently say that it has nothing to do with us. We're providing the organization with eighty-gigs of throughput in all directions to the firewalls. Troubleshooting poorly-performing applications is easier now because we can say that the bottleneck is not in the data center.
We could be doing much more with our Nexus 9K switches, but they are not doing as much as they are capable of because we only have layer-two in our data center. This is the way our data center was set up and how the executive team wants it to be run. In larger data centers and larger companies, they're using the full capabilities.
My recommendation for anybody who is researching this solution is to ask for a demonstration from your local Cisco support. We had an awesome support engineer who did a demo with us. He brought in four switches and set up DCNM. We got to see the benefits of how DCNM would help us. We're transitioning to more automation because we have fewer people than we did, so the DCNM product is awesome. It used to be a twenty or thirty-minute process to add a VLAN in our data center, and now it takes approximately three minutes. The Cisco DCNM and the 9K switches were the beginning, to show what we can start doing as a network team to leverage the technology that we have.
I would rate this solution a ten out of ten.

Network Engineer at Applied Materials
Responsive technical support but need better certifications and training
Pros and Cons
- "The setup was very easy, but managing it in operations was very complex."
- "We lag on the configuration. The changes make a difference in troubleshooting."
What needs improvement?
We really lag on the AC infrastructure where the configuration and the changes make a difference in terms of troubleshooting.
The product improves us when we see an expert and L1/L2 engineers for support. We have a dependency there. A simple configuration makes a big difference. It can create more chaos inside the network. We need to make sure when we make changes in one platform and it impacts other platforms, that the technical problems don't reach the end users.
There should be better certifications. More training should be provided before we get into this product.
What do I think about the stability of the solution?
We are just migrating to Cisco Nexus as a newer product. We are looking for similar features in Arista. We are closing the gap from Cisco ASA to an Arista ASA environment. This gives us a very stable network when compared to Cisco.
How are customer service and technical support?
I get very good support from Cisco. The response was very fast when compared to other vendors.
Which solution did I use previously and why did I switch?
I advise anyone to invest in a new solution because we do a periodic refresh every three years. For any product we buy, we ensure it is in the warranty and it is the leader in the market.
We go through the Gartner studies to understand the leaders in the market. Then, we get the solutions from the partners and go over them. We do a case study with the other competitive companies on the product they use and their experience with it.
How was the initial setup?
The setup was very easy, but managing it in operations was very complex. The VLANs are different. We have a network outside and inside of the ASA infrastructure.
It is not possible to provide privileged access to L1 or L2 engineers. If you provide L3 access, there is a chance that they mess up the network by making smaller changes that you don't want.
What about the implementation team?
We implemented Cisco Nexus through a consultant.
Which other solutions did I evaluate?
Another option was Aruba Networks.
What other advice do I have?
On a scale of 1 to 10, I would rate this product a 6 or 5. The reason is that we are into Cisco for a long time. They have been very good supporters since we began the network environment.
For any technology on the education part, for the training and decisions, there are more resources available than when compared to other partner products. Planning technology through Cisco for our training sessions and getting it implemented with other products is what we do now.
Currently, we are assessing the leaders in the market for the data-container environment and SD-WAN solutions. VeloCloud was suggested by colleagues of neighbor companies.

Principal Engineer 2 at Charter Communications, Inc.
Has good performance, flexibility, configuration, and cost
Pros and Cons
- "The most valuable feature of Cisco Nexus is the performance, flexibility, configuration, and cost. It's not a traditional pricing model from Cisco. They've offered our company a considerable reduction in price. That makes Cisco Nexus now very competitive with other vendors."
- "One improvement needed is support for Multi-CAD scale that we were concerned about. We're not hitting any limits at this point."
What is our primary use case?
Our primary use case for the Cisco Nexus is for a VXLAN environment with some video multicast.
How has it helped my organization?
I don't think we've been using Cisco Nexus long enough to know accurately how it is improving our organization. Our first deployment was about a month ago.
What is most valuable?
The most valuable features of Cisco Nexus are the performance, flexibility, configuration, and cost. It's not a traditional pricing model from Cisco. They've offered our company a considerable reduction in price. That makes Cisco Nexus now very competitive with other vendors.
What needs improvement?
One improvement needed is support for Multi-CAD scale that we were concerned about. We're not hitting any limits at this point. There were concerns about the amount of server capacity that was going to be available. We like to see things that are already there as opposed to being told where they will be.
What do I think about the stability of the solution?
The stability of Cisco Nexus thus far has been excellent. We had some initial issues with some non-Cisco optics, third parties claiming compatibility when they weren't compatible.
What do I think about the scalability of the solution?
We've not had a scale-out yet. Cisco Nexus looks very valuable. We're starting to deploy them in other environments as well.
How are customer service and technical support?
Cisco technical support for the 9000 is good. During our issues, we had excellent technical support. The support issues required around 40 hours. We had Cisco engineers available for the entire time. It was impressive.
Which solution did I use previously and why did I switch?
In the production of our network, we've grown in scale, and that's really what it came down to. Previously we wouldn't have thought that a Nexus product was comparable to some of the other vendors, like Arista and Juniper. But the features of the 9000 brought it into line with the capabilities of other vendors that we used.
How was the initial setup?
The setup is straightforward. Nexus uses options that our engineers are familiar with. The advantages were that we could leverage the knowledge that we already had.
What other advice do I have?
On a scale of 1-10, I would rate it a 9. Cisco is very competitive with the other companies that are out there. I would recommend them. We've had very good luck.
Cisco is a leader. They help us with the deployment at a lower cost.

Helps us with troubleshooting and uptime management in keeping a healthy network but needs better granularity
Pros and Cons
- "Cisco Nexus has improved the way our organization functions through the troubleshooting. We had issues where we've seen our links saturated. We were able to determine what was being processed on the link."
- "I would like to see more granularity."
What is our primary use case?
We use Cisco Nexus primarily to check the health of our links. We use it to make sure if our links are good or not. It really helps with troubleshooting.
How has it helped my organization?
Cisco Nexus has improved the way our organization functions through the troubleshooting. We had issues where we've seen our links saturated. We were able to determine what was being processed on the link.
It has reduced the complexity of our network monitoring because I'm able to drill down quickly and figure out what's going on.
It has helped us make sure that we have the best uptime that we can have.
What is most valuable?
Although it could be better, you can get the granularity depending on the amount of time that you drill into it.
What needs improvement?
I would like to see more granularity.
What do I think about the stability of the solution?
The stability of the solution is very good.
What do I think about the scalability of the solution?
It scales very well.
Which solution did I use previously and why did I switch?
We did not have a previous solution.
How was the initial setup?
Cisco Nexus is straightforward to set up. We just pointed our logs to it. It's pretty easy.
What about the implementation team?
We used a consultant. I didn't install it, I don't know exactly how it was done.
What was our ROI?
We have seen ROI based on the fact that we have more uptime.
What other advice do I have?
On a scale of 1 to 10, I would rate this product a seven because it's helped out a lot in terms of troubleshooting.

Network Engineer Principal
Flexible, reliable, and the VPCs operate accurately
Pros and Cons
- "The flexibility, how accurately the VPCs operate as well as the redundancy built into it with the VPCs are the most valuable features."
- "There's been a little bit of bugginess in the code, but that happens."
What is our primary use case?
Our primary use case of this solution is for our data center environment.
What is most valuable?
The flexibility, how accurately the VPCs operate as well as the redundancy built into it with the VPCs are the most valuable features.
What needs improvement?
I would like to see improved ISSU.
What do I think about the stability of the solution?
It's a stable solution, but there are a few bugs here and there in it and it would be nice if they weren't there. The Mac looping is an issue as well.
The ISSUs sometimes go down.
What do I think about the scalability of the solution?
It's very scalable. You can go up or down in size as much as you want.
How are customer service and technical support?
Their technical support is outstanding. We had some issues at the core layer in our Nexus data center, and the 7Ks were hitting a bug, and we couldn't figure that out until we got really deep into debugs. Their tech support was able to resolve that.
Which solution did I use previously and why did I switch?
We had our Cisco account rep and they helped us figure out what the right solution was for us.
How was the initial setup?
The initial setup was rather complex because it was my first time deploying Nexus, and you have to turn on all the features to make them all work and that's something that you don't have in any other Cisco switch. It threw me for a loop. But once you figure out the resources and setting up the VDCs and everything, you're good.
What about the implementation team?
I deployed this solution myself.
What was our ROI?
We definitely got ROI from Nexus and a pretty short term because the pure redundancy and the uptime, is a real value add for us.
Which other solutions did I evaluate?
We were using another solution and we went with Cisco because it has more features. Also because Cisco is reliably good; nobody ever got fired for choosing Cisco.
We were looking at Arista and Juniper, but we ended up going with Cisco, mainly because of the features.
What other advice do I have?
I would rate this product a pretty solid eight out of ten because it's been pretty reliable and good and it's done what it's supposed to do. There's been a little bit of bugginess in the code, but that happens.
I would consider the cost and functionality that you need and consider this in between ACI and a Nexus deployment. Right now, ACI isn't super mature, and if you don't have people that are able to actually dig in and really learn ACI, Nexus still might be the best solution.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

What do I think about the stability of the solution?
Stability is much better than it was.
What do I think about the scalability of the solution?
Scalability is good.
How are customer service and technical support?
Their technical support is better than other companies.
How was the initial setup?
The setup can be easy and complex depending on the product and features we're using.
What about the implementation team?
We used in-house resources for the deployment.
What's my experience with pricing, setup cost, and licensing?
Our licensing costs are yearly.
What other advice do I have?
I would rate this solution a nine out of ten. Nexus is better than other switches so I would advise going with this solution.
