The primary use case is for data center switching. This is what it was intended to do.
Systems Engineer at a tech services company
You can automate it. It also has a lot of insight into monitoring and traffic.
Pros and Cons
- "It scales very well. When you increasingly scale with it, it makes the product easier to work with."
- "The interface is sometimes slow. I receive a lot of weird errors when I try to install apps, such as contract apps, which should give me a nice visualization of all the contracts. However, it just doesn't load, etc."
What is our primary use case?
How has it helped my organization?
I am a partner, and I implement the solution for other organizations.
What is most valuable?
- It scales very well. When you increasingly scale with it, it makes the product easier to work with.
- You can automate it.
- It has a lot of insight into monitoring and traffic. However, this could also be improved.
What needs improvement?
The interface is sometimes slow. I receive a lot of weird errors when I try to install apps, such as contract apps, which should give me a nice visualization of all the contracts. However, it just doesn't load, etc.
I would like more thought put into the way the graphic part of the monitoring is rendered. When you have a lot of contracts, you can't understand the graphics because they are so loaded.

Project Manager at Radio France
The product makes sense from a compatibility point of view since our network is entirely Cisco products
Pros and Cons
- "The stability is perfect. We have had no problems with Cisco ACI."
- "The initial setup was a bit complex."
What is our primary use case?
We use it to design and manager our network. There are a lot of places inside the building, and we have to bring the new network everywhere to help us.
How has it helped my organization?
We use Cisco everywhere in our network, so it makes sense from a compatibility point of view.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
The stability is perfect. We have had no problems with Cisco ACI.
What do I think about the scalability of the solution?
We have not thought about scaling at this time.
How are customer service and technical support?
As the project manager, I don't call the technical support.

Network Architect at a computer software company with 10,001+ employees
Reliable, very scalable, and makes it easy to do global configurations
Pros and Cons
- "It is very easy to do the configuration after you know how to work with the product. It is global, so you change one interface, and changes are reflected on every switch."
- "Its graphical user interface (GUI) is not as user-friendly as it could be."
What is our primary use case?
This is software-defined networking. So, all the configuration done on a customer network is done with this application.
I am using the version before the latest version.
What is most valuable?
It is very easy to do the configuration after you know how to work with the product. It is global, so you change one interface, and changes are reflected on every switch.
What needs improvement?
Its graphical user interface (GUI) is not as user-friendly as it could be.
It is quite expensive.
For how long have I used the solution?
I have been using this solution for about a month.
What do I think about the stability of the solution?
It is stable and reliable.
What do I think about the scalability of the solution?
It is quite scalable. It is one of the most scalable products we have come across.
We have five people who are using it in our company in Portugal.
How are customer service and technical support?
We haven't had any need.
Which solution did I use previously and why did I switch?
We were using a different solution, but it was not for software-defined networking. It was for a different type of networking.
How was the initial setup?
It is very complex. All the configuration that needs to be done on the Cisco ACI is very complex. We have to create base policies for all the network devices and then implement it. Afterward, it is rather easy, but the implementation part is a long and complex process.
After it is deployed, it is rather easy because all the configuration is done automatically. You only need to do regular visits to see that it is working and do some regular tests. It is not that difficult.
What about the implementation team?
We took Cisco's help.
What's my experience with pricing, setup cost, and licensing?
It is quite expensive. It is not at all on the cheap or medium side.
What other advice do I have?
I am quite new to this product, and I am still learning it. My recommendation would depend upon the size of the organization. It is one of the flagship products of Cisco, but it is not a product that you can implement for any customer. It is more suitable for medium to large enterprises.
I would rate Cisco ACI an eight out of 10.
Which deployment model are you using for this solution?
On-premises

Technology Consultant at a tech services company with 51-200 employees
Good performance throughput and technical support
Pros and Cons
- "The most valuable feature is the throughput that it offers."
- "Training for this product is available from institutions but it is not available online where you can get users trained easily."
What is our primary use case?
I am a technology consultant and my company is implementing this product for data center networking.
What is most valuable?
The most valuable feature is the throughput that it offers.
What needs improvement?
Training for this product is available from institutions but it is not available online where you can get users trained easily. It would be better if the training for our users was easier to get.
Cisco ACI should have better integration with a hypervisor such as VMware, Hyper-V, or KVM. This would give us a one-window solution for our networking, compute, and storage.
For how long have I used the solution?
I have been working with Cisco ACI for about two years.
What do I think about the stability of the solution?
Our customers are very much satisfied with the stability. We do not have any issues with it.
What do I think about the scalability of the solution?
It is scalable, although it depends on the design and the customer.
This is not a product for small-scale users. If we have customers with large data center requirements, we offer them Cisco ACI. For example, it is not for small enterprises without a lot of services running in their data center.
Scaling is easy because we can add, as required. While it depends on the design, scalability is not normally an issue.
How are customer service and technical support?
We have received technical support when required and we are pretty satisfied with the support we get.
How was the initial setup?
The initial setup is okay. It is not very complex, although I would not say it is very user-friendly because it is different from what we have been using. The best way to put it is that for me, it is new and it is straightforward.
A complete deployment, including the migration from their existing system, will take approximately two months.
What about the implementation team?
Initially, we had Professional Services assist with hour deployment.
What's my experience with pricing, setup cost, and licensing?
This is an expensive solution.
What other advice do I have?
Overall, this is a good product but if it had better integration then I would rate it a full ten out of ten.
I would rate this solution an eight out of ten.
Which deployment model are you using for this solution?
Private Cloud

Network Manager at a university with 501-1,000 employees
Integration with vCenter saves us time and effort
Pros and Cons
- "The integration with vCenter means that when I create something on the network, it only has to happen one time instead of many times for our many virtual hosts."
- "There should be an alternative "ACI Light" solution for smaller-sized enterprises."
What is our primary use case?
We use this solution for our data center infrastructure. We are a small, private university, supporting a mix of cloud and on-premise applications.
How has it helped my organization?
This solution saves us time. The integration with vCenter means that when I create something on the network, it only has to happen one time instead of many times for our many virtual hosts.
What is most valuable?
The most valuable feature is the integration with vCenter, as it makes it easier for the systems and network to interoperate.
What needs improvement?
I would like to see simpler contract building, engineering, and architecture.
There should be an alternative "ACI Light" solution for smaller-sized enterprises.
For how long have I used the solution?
Three years.
What do I think about the stability of the solution?
This solution has been very solid. We've had no problems in the three years that we have been using it.
What do I think about the scalability of the solution?
We haven't really grown or changed the network since this solution was installed, so I cannot comment on scalability.
How are customer service and technical support?
Technical support for this solution is great. The ACI guys have been some of the best technical support people that I've worked with at Cisco. They just seem to know things better than the other groups within their support infrastructure.
How was the initial setup?
The initial setup of this solution is complex. Our environment is not very complex, but the product itself is very complex. It takes a lot of steps to configure.
What about the implementation team?
We used a partner that Cisco recommended to assist us with the implementation.
We were one of the first implementations, and I think we were used at the lab during our installation. Some of the things that you learn over time were not known, so it could have been done better.
What was our ROI?
We have seen partial ROI. However, that is probably more our fault than the product's fault because we haven't leveraged the tools that are there.
Which other solutions did I evaluate?
Three years ago when we were starting with this process, the industry said that software defined networking was the way we had to go. At the time, this is the only solution that was available.
I was one of the proponents of this solution.
What other advice do I have?
My advice for anybody considering this solution is to really look at the size of your organization. Ours is kind of in the middle in terms of size, between large and small. So, ACI may be a little bit of overkill for the size of the shop that we have. If you have a large organization then it's a good product. If, on the other hand, you are a little shop, it is probably more than you need.
This is a good solution, but no product is perfect.
I would rate this solution an eight out of ten.

IT Network Engineer at MANGO
Has improved communication between my endpoints in the data center but the setup is complex
Pros and Cons
- "The biggest benefit has been that it has improved communication between my endpoints in the data center."
- "I would rate this solution a five out of ten. Not a ten because I don't have good training for this solution. I am now implementing Cisco ACI in the company. It's not 100% on the network. It's on 25% approx, more or less."
What is our primary use case?
Our primary use case is to interconnect both data centers in my corporation.
How has it helped my organization?
The biggest benefit has been that it has improved communication between my endpoints in the data center.
What needs improvement?
I would like to see better training. I don't have good training with this product. If I did, I probably would be able to solve all of the problems during the installations.
What do I think about the stability of the solution?
It's very stable.
How are customer service and technical support?
Their technical support is fantastic. Whenever I have a problem, our partners at Cisco support answer quickly.
How was the initial setup?
The initial setup was complex. If I didn't have my partner's support, I probably couldn't deploy Cisco ACI in my data center.
What about the implementation team?
We implemented through a partner. I trust our partner, and I trust any of their recommendations and their deployments.
What other advice do I have?
I would rate this solution a five out of ten. Not a ten because I don't have good training for this solution. I am now implementing Cisco ACI in the company. It's not 100% on the network. It's on 25% approx, more or less.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

What do I think about the scalability of the solution?
It has very good scalability.
How are customer service and technical support?
Their technical support is very good. We had a problem and Cisco gave us the best engineer to resolve the issue.

What about the implementation team?
We used our own company to deploy the network.
What's my experience with pricing, setup cost, and licensing?
It's expensive but the product is very good. I have never found another partner like Cisco with a solution like this and with great support.
Which other solutions did I evaluate?
We also looked at Juniper but their solution isn't stable so we didn't go with them.
What other advice do I have?
I would rate it a seven out of ten. It's a good product, and Cisco has a very good support team and very good network engineers.
Of course I would recommend this product. We work with Cisco because they have many possibilities to work with very good support.
