Performs well, good port flexibility, and scales out easily
Pros and Cons
  • "The most valuable feature is performance."
  • "There is an ongoing problem with the limitation of the TCAM table, which is that it doesn't have enough memory to allow you to be really granular with your policy."

What is our primary use case?

I am an engineer and work primarily with our data center network and data center security. The Nexus switch is a data center switch and I have a lot of recent experience with it. My company is a solution provider and this is one of the products that we sell to our clients.

What is most valuable?

The 9000 series works really well in the spine-and-leaf architecture and gives you capabilities up to 400 gig.

The most valuable feature is performance. Not many customers are using the 400 gig speed yet, but you do have flexibility as if you're going to run the ports at 10 gig, 40 gig, or 100 gig. That port flexibility is really important.

What needs improvement?

There is an ongoing problem with the limitation of the TCAM table, which is that it doesn't have enough memory to allow you to be really granular with your policy. Without enough memory, it requires manual manipulation if you exceed or get near to the TCAM limits. They have improved it, but in the early days, it took down some companies.

For how long have I used the solution?

I have been using Cisco products for many years and have experience with the Nexus line since it was first released.

What do I think about the stability of the solution?

These switches are very stable.

What do I think about the scalability of the solution?

The spine-and-leaf architecture is very scalable. If you need more ports to plug servers in, you add more leaves. If you need more throughput then you add more spines.

All of the switches at the top are the spine, and those plug into those are the leaves, and then the servers plug into the leaves. It's highly scalable, because if you have more servers then just purchase two more switches. If you need more throughput and better performance, then you just purchase two switches for the spine. You can continue to scale out the model very simply.

Which solution did I use previously and why did I switch?

The Nexus 9000 platform is by far the best-selling and most popular, and there are a couple of reasons for that. It's less expensive than a 7K or 5K solution and in fact, we hardly sell the 5Ks anymore. The 9000 really works well in the spine-and-leaf, which is the current architecture.

How was the initial setup?

The initial setup is really straightforward and if you use ACI, running on top of the Nexus 9K, you don't really have to do anything but plug the switches in. The software manages all of the policy.

Without ACI, setup requires the use of the command line, which is the same as it's always been.

What about the implementation team?

The maintenance can be handled by one person or a small team.

What's my experience with pricing, setup cost, and licensing?

The Nexus 9000 is very competitively priced. 

What other advice do I have?

The Nexus Dashboard is a relatively new product that is in the portfolio for the data center. It hosts the multi-site orchestrator and has functionality for self-healing and self-optimizing of the data center network. It's Nexus' best work.

My advice for anybody who is considering this solution is that if you're looking to cut costs in the data center, there's not that big of a difference between a Cisco switch and other switches. But, when it comes to things like storage, between the most expensive and the least expensive, there's a lot of different pricing in there. So, I wouldn't cut costs on your switches. I would suggest looking at other areas where you can cut costs.

I would rate this solution a ten out of ten.

Valuable data center features, continual feature refinement, highly scalable and stable.
Pros and Cons
  • "Cisco is refining the features all the time and you can see this in all the different vendors."
  • "They could improve on having different technologies between product models."

What is our primary use case?

I use the solution in the customer's companies. I have used many different version of the solution. 

What is most valuable?

I find all the data center features to be most valuable, such as VXLAN and OTV. The ACI and FEX connectivity are good features too. Cisco is refining the features all the time and you can see this in all the different vendors.

What needs improvement?

They could improve on having different technologies between product models. The management dashboard could be better if it could handle the Catalyst and the Nexus at the same time. If Cisco could find management connectivity between the DMA center and the ACI connectivity this would be helpful.

For how long have I used the solution?

I have been using the product for more than ten years.

What do I think about the stability of the solution?

The solution is stable.

What do I think about the scalability of the solution?

I have found the scalability good with this product.

How are customer service and technical support?

The support we received was excellent.

Which solution did I use previously and why did I switch?

I have worked previously with Catalyst version 6500, 4500, and 3750 series, most of them.

How was the initial setup?

The setup of the solution was easy.

What's my experience with pricing, setup cost, and licensing?

The price of the product is reasonable.

What other advice do I have?

In all the benchmarks and testing that I did, I found the best solution to be Cisco. I recommend the product. They have a good product with all the features that are required. 

I rate Cisco Nexus a nine out of ten.

One of the most stable solutions, with good support from Cisco
Pros and Cons
  • "The most valuable features are extensions and recorded scalability."
  • "The initial setup wasn't simple or user-friendly."

What is most valuable?

The most valuable features are extensions and recorded scalability.

What needs improvement?

Areas for improvement would be the delivery timeline for the actual model, the length of which means we have to sacrifice a range of models because we can't wait six months for delivery.

For how long have I used the solution?

I've been working with this solution for a few months.

What do I think about the stability of the solution?

In terms of stability, it's so far so good - we haven't faced any big issues at this point.

What do I think about the scalability of the solution?

We want to extend out to other regions, which is very easy to achieve if compared to the typical traditional legacy layer 2 switch, layer 3 routing approach.

How was the initial setup?

The initial setup wasn't simple or user-friendly. We're still in the process of fully deploying - currently, we've been working on it for around three months.

What about the implementation team?

We used the Cisco team to implement, with whom we've had a good experience. We've also had support from HPE, who are very technically strong and able to answer any questions we have on the spot.

What's my experience with pricing, setup cost, and licensing?

I don't like the Smart Licensing models that Cisco uses.

What other advice do I have?

Cisco is one of the most stable solutions, regardless of which model. I would give this solution a rating of eight out of ten.

Which deployment model are you using for this solution?

Exceptionally stable, scalable, and helpful support
Pros and Cons
  • "The solution is stable."

    What is our primary use case?

    We are using the Cisco Nexus as our core switch for our main backbone.

    For how long have I used the solution?

    I have been using Cisco Nexus for approximately two years.

    What do I think about the stability of the solution?

    The solution is stable.

    Nowadays, every five years technology changes. However, you will find customers who are using the same Cisco switch which has a life span of five years or seven years, will still be using them for more than 10 years without raising a single ticket. This is the confidence they have in Cisco. This is my personal customer experience, it makes it difficult for us to generate business. We can do a technology refresh or a product replacement But when there is Cisco, it is tough for any person to replace that solution. Cisco has that X factor in their solutions, and specifically with networking. Nexus is definitely their bread and butter. It is an exceptional solution.

    What do I think about the scalability of the solution?

    Cisco Nexus is scalable.

    We have approximately two customers.

    How are customer service and support?

    The Technical support of Cisco is really good. It is a core switch, you require three to four hours, same business day support. They give you a good resolution within that time. They are good at troubleshooting.

    How was the initial setup?

    The installation is straightforward. If you have someone who is certified to do the implementation of Cisco Nexus they can do it quickly. 

    All other switches, such as distributed switches and access switches connect to the Cisco Nexus switch. If you have done everything correctly including the sizing, there should not be an issue at the time of installation.

    What about the implementation team?

    we have one manager and one engineer for the deployment and maintenance of the solution.

    What's my experience with pricing, setup cost, and licensing?

    The subscription model and price could be better.

    What other advice do I have?

    I would recommend this solution to others.

    I rate Cisco Nexus an eight out of ten.

    Scalable, stable and easily installable, but more expensive than Juniper switches and lacks a single switch for multiple ports
    Pros and Cons
    • "The initial setup is easy."
    • "It would be nice if the solution offered multiple types of port support."

    What needs improvement?

    Cisco Nexus could also have better documentation.

    Moreover, it would be nice if the solution offered multiple types of port support. It does not have, for example, a single switch for both internet and fiber ports. 

    For how long have I used the solution?

    I have been using Cisco Nexus for around 10 years.

    What do I think about the stability of the solution?

    The solution has demonstrated stability thus far. 

    What do I think about the scalability of the solution?

    The solution is scalable.

    How are customer service and technical support?

    The technical support is fine.

    Which solution did I use previously and why did I switch?

    For Cisco, we use Nexus and 2900.

    How was the initial setup?

    The initial setup is easy.

    What's my experience with pricing, setup cost, and licensing?

    As I deal with the technical aspects of the solution, I am not in a position to comment on the price. 

    Which other solutions did I evaluate?

    We consider Juniper switches to be more affordable.

    What other advice do I have?

    I use the solution in my own company. It works.

    There are around 500-plus devices being utilized in our organization. 

    My advice to others is that they get initial hands-on experience in a lab environment. This should involve a proper grasp of the solution's features, such as that which concerns troubleshooting and may involve a different setup. Only at this point should one enter the production stage. 

    I rate Cisco Nexus as a seven out of ten.

    Beneficial logical tenant segregation, installation straightforward, and scalable
    Pros and Cons
    • "We have found that logical tenant segregation to be the most useful feature."
    • "The software is not as mature as it could be and needs some integration improvements with other orchestrators."

    What is our primary use case?

    We use the solution in a data center farm.

    What is most valuable?

    We have found that logical tenant segregation to be the most useful feature.

    What needs improvement?

    The software is not as mature as it could be and needs some integration improvements with other orchestrators.

    For how long have I used the solution?

    I have been using the solution for three years.

    What do I think about the stability of the solution?

    When it comes to the stability we had some issues with some software features due to a release bug. The hardware itself is pretty stable. 

    What do I think about the scalability of the solution?

    The solution is scalable.

    How was the initial setup?
