Cisco ACI Scalability

Syed Ali Wajahat
Sr Network and Security Consultant (SDN & Security) at a media company with 1,001-5,000 employees
In terms of scalability there is just one limitation. When you want the security rules and features to be applied on the application NIC level - on the virtual NIC level, on the network interface level, on the application itself, on the virtualization domain - you cannot do that. The application needs to reach via API so you can apply the security policy. Then the security policies will be applied and then it can talk to other applications. This is one thing that is missing on ACI. But you cannot say that it's actually missing because that's the overlay approach of SDN; it's not underlay like NSX. View full review »

I would give the solution's scalability an eight out of ten. The scalability options are really good. You just connect the leaves to the spine and it comes up. The scalability is not an issue. The biggest environment I've worked with has two spines, spines with 16 leaves. In terms of the number of users on it, initially it was really difficult for customers to adopt the new technology because it was a wholly new concept. Now, with time, and as ACI comes out with the new features, and the stability is really strong, the adoption is really good. According to Cisco engineers, they have customers who have gone up to 6,000 users. Regarding the possibility of our customers' increasing their usage of ACI, we don't see that much indication of it, because what the customers are looking is more along the lines of having their fabric be more redundant. One of the features engineers are looking for is the Endpoint Tracker, which has had some issues. It is not that user-friendly. View full review »

Technology Support Specialist at Fujitsu
It's scalable because of the spine-and-leaf infrastructure. You can add spine and leaf. I haven't scaled it that much. We've only used three or four leaves into the ACI infrastructure. But I believe the scalability is good. View full review »

IT Evolution Manager at a aerospace/defense firm with 1,001-5,000 employees
We are not that big to reach the limit (or edges) of this technology. Its scalability is fine. It is very easy to scale. Today, doing changes to the infrastructure is a nightmare. Every single device has different programs and programmatics. However, with this tool, you simply plug and play. When you want to scale, you add one piece, and it's done. It works. View full review »
SystemsNd760
Systems Network Manager at a non-tech company with 1,001-5,000 employees
Scalability is definitely something that we're looking at, and it's one of the attractive features of ACI for us. It is easy to do. The way ACI works is it is one configuration interface. If you want to add more then you just plug it in. I would not call it plug-and-play, but they've made it to the point where it is very close. This is important to us because we just don't know how our business is going to grow, and change, over time. It's a moving target for us. If we buy something today, and then there is a demand for more capacity in the data center, then we just have to buy more devices and plug them in. We don't have to do anything else. The infrastructure just becomes available for us to use. This differs considerably from the traditional Cisco, which involved a lot of command lines and configuration. View full review »
Mark Hayden
Lead Network Engineer at a consultancy with 10,001+ employees
Scalability is great in a Cisco ACI environment. But when you're migrating from an old data center into ACI, there are some challenges. In all the people that manage it, most are just trying to throw entire networks with multiple environments on them into ACI. It's good but it also has a lot of challenges for us. View full review »
SeniorNe9978
Senior Network Engineer at a pharma/biotech company with 1,001-5,000 employees
Scalability is definitely something that we are looking at and that's one of the attractive features of ACI for us. It's one configuration interface and if you want to add more interface you just buy more gear and plug it in. It's almost a plug and play solution. We just don't know how our business is going to grow and change over time. We can buy and implement something today and they can come and say that they are doing an acquisition or some sort of growth or new business venture and we need more capacity in the data center. With ACI, if you need more capacity you can just buy more and plug them in without needing to do anything else. All of the sudden that infrastructure is there for me to use, configure, and add stuff to. View full review »

The scalability is very good, based on the spine-leaf structure. You can increase the number of leaves and you can also scale the spines. You can deploy four spines, eight spines. View full review »
PaulIlavarasu Balasekar
Technical Lead at a tech services company with 10,001+ employees
In terms of scalability, you can go with the two-spine and get very good bandwidth, but if you need more than this you can increase the spine count. If you need more devices you can increase the leaf count. Scalability is there. View full review »
Byron Hooper
Senior Network Engineer at a insurance company with 201-500 employees
In terms of scalability, we haven't grown the deployment yet and we are nowhere near capacity. But it seems like it is relatively scalable in terms of what we could use. It's a matter of what do we need. I just haven't had the opportunity to increase the scale of what we have right now. View full review »
NetworkEec9b
Network Engineer at CS Computer Systems
The scalability is impressive. I think the best thing about that is the vendor-agnostic part. In the lab, we did a VMware deployment from what I heard it doesn't matter how the VM is deployed, it can integrate with ACI and you can manage it from the Epic controller. View full review »

Cisco ACI is very scalable. There's no real length to it. If you look at ACI, you can have an endless number of layers. The size of our environment is about 2,000 nodes. It's not a huge network, it's pretty medium-sized. View full review »

Network Architect at a comms service provider with 10,001+ employees
Scalability is another point for our cloud project. We use Cisco ACI, because when we expand the network another 10 to 20 switches more, the switches are easier to implement now. We connect the new switches to the spine infrastructure, then they are the switches are ready to configure. View full review »
