"Cisco's technical support team is very good."
"Cisco technical support is great."
"The most important aspect of Cisco ACI in my opinion is the ease of management. Other solutions, like traditional solutions and pricier solutions—or even fabric and PAT—you have to do many configurations on a box-to-box basis, With Cisco ACI, you go on the AP and do some "next, next finish" installer."
"The most valuable feature is the throughput that it offers."
"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."
"The stability is quite good."
"We had different networks and combined them with ACI so we could have the control of one controller-based network. Also, everything is combined now."
"I have found VMware NSX to be easy to use."
"Overall, I would say the solution has been quite stable."
"It gives more security and micro-segmentation. It helps to set network configurations in an easy way."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
"The most valuable features are security and dynamic routing."
"The most valuable features are stability and low cost."
"I have found the solution to be stable."
"The most valuable features are the micro-segmentation and integrated security options."
"It would be great if ACI would include the next generation firewall feature."
"I would like to be able to test the upgrades in a simulation before implementing them in production because not everyone has a lab."
"Before version 5, you could manage your firewall or load balancer from the AP. It was very basic and now they removed the whole features in the new version, so you cannot manage your load balance or firewall from your AP on L2, L4, and L7 services."
"Its graphical user interface (GUI) is not as user-friendly as it could be."
"Training for this product is available from institutions but it is not available online where you can get users trained easily."
"From my point of view, troubleshooting issues relating to ACI can be a little bit complicated to perform."
"Technical support needs to be more helpful. It's rare that you get a knowledgeable person."
"Our company had a lot of issues with the starter kit."
"Quite a complex solution."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
"The technical support could use some improvement."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"In the future, the solution should be compliant with internet NIC."
"Everybody needs a network to connect to, and VMware doesn't readily provide one."
"We have been satisfied with the technical support. They were able to solve our problems. However, they could be faster."
"VMware NSX only supports some platforms like KVM."
