What is most valuable?

I like a lot about this solution. They are very high-performance switches and they are made for lossless data, so they're a good play in the customer environment.

How has it helped my organization?

This product is made for lossless data, so it's a very high-performance switch. If there's one place you don't want to lose data, it's in the data center. The 9Ks support speeds of 40-gigabit and… more»

What needs improvement?

The 9K was developed to support ACI, the software-defined data center technology. For this reason, there is no feature parity between the 9K and the 5K or 7K, which means that it is harder to position… more»

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

What needs improvement?

I would like to see a lot more integrations with the rest of the Cisco portfolio. I would like to have ACI embedded into HyperFlex, as an example.

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

Our previous solution was legacy, three-tier networking. The market is changing, and software-defined networking is becoming the way to do business. Our network was the last piece to keep up, so it… more»

What other advice do I have?

My advice to anybody researching this solution is that you have to test it. You can't take the stats on paper. Rather, you have to actually do the R&D to see it in a real environment. I think a lot of… more»

Which other solutions did I evaluate?

We evaluated solutions from Cisco, VMware, and HP. Cisco's solution, from a software perspective, may be slightly behind, but from a hardware perspective, it's the most scalable and best to support.
