Cisco Nexus Review

Flexible, reliable, and the VPCs operate accurately


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. 

If you previously used a different solution, which one did you use and why did you 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.
