Flow monitoring has improved planning for east-west traffic and real-time capacity decisions

Cisco Nexus Dashboard Fabric Controller (Formerly DCNM) helps to understand the flows and data plane capacities, which are the primary use cases. Usually, people struggle with east-west traffic flow when they need to decide on firewalls or products. People typically understand north-south traffic flows but usually miss the east-west traffic flows in data centers. I was focusing more on this so that people can accordingly plan, such as after F5, the number of servers, the number of sessions needed, and whether we need to plan the interface for groups from the line capacity perspective. This kind of information was valuable to us. The real-time telemetry feature was beneficial. When experiencing performance issues, I could determine if there were any issues related to flows or areas where bottlenecks were occurring.

A valuable, impressive, and portable product that saves time and has great scalability and stability

It just saves time. We have run into situations where contractors come in, and they plug in a WiFi device that is handing out DHCP addresses, which affects the rest of the network. To be able to quickly identify from where the problem is originating, you need a network tool that can identify the device that is doing this. It just brings into clear focus the exact issue when there is a problem or outage. When there is a crisis and you've several people wanting to know an estimate of when things are going to be back up and running again, you need to have answers. I have been at places that didn't have a tool like that. I know one place that had an outage for almost a week, and it was craziness. It turned out to be just a bad cable. That's all it was. They were having trouble with their email server, which was an on-premise email server, but emails were taking six hours to appear. The whole problem was because of a bad network cable. When I plugged in the Fluke analyzer, it analyzed and told me immediately that there were transmission errors on this one port from one switch. It told me this within 10 minutes. It is an incredible product.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The monitoring system in this product is valuable, providing a clear indication of what's going on in the network and the server processing, power, etc., and the user interface is also very good and very informative."

"Data Center Network Manager is absolutely stable."

"The solution is very stable and it has never crashed on us."

"The product makes the management of our environment simpler."

"We have had a good ROI from Data Center Network Manager, and there is also a facility on Cisco's website to calculate the ROI from adopting this solution."

"The monitoring capability is the best in Cisco Data Center Network Manager. It helps me improve network management tasks and optimize processes."

"The most valuable features of Cisco Data Center Network Manager are consistency and the core server. The teams have had a good experience."

"More than good enough as we have new clients everyday connected using this product"

More Cisco Nexus Dashboard Fabric Controller (Formerly DCNM) pros

"I think it cuts down the time to resolution drastically for an environment that would not have the ability to do these packet captures."

"It has streamlined and simplified troubleshooting complex networking problems that would be nearly impossible to uncover with other products."

"For me, just resolving our one VLAN problem really makes it worth it."

"When we do a capture, it gives us the details of where the problem is and what it could be."

"The pre-site survey and the AirMagnet site survey help my company in pre-sales and post-sales."

"I like the fact that it can map my whole network when I plug it into my router, my switch, that it can literally discover nodes and clients."

"OptiView XG helps us troubleshoot problems faster than we would normally be able to."

"It's the one product that we go to when we have a problem or need to get information, because it can do so much."

More OptiView XG [EOL] pros

Cons

"Data Center Network Manager is a little complex because it includes a lot of hardware to be installed, so making this simpler would be an improvement."

"It's very costly."

"It would be nice to have the ability to more easily collect information from other software when doing some types of analysis."

"The solution needs to improve reports."

"I do not believe it integrated well with different infrastructures for hybrid environments."

"The initial setup is challenging."

"If the customer thinks about using additional solutions, Cisco should make sure they are not left out."

"The visibility of applications is not great, which is why we study upscalability."

More Cisco Nexus Dashboard Fabric Controller (Formerly DCNM) cons

"It can’t scale to even one user because it crashes when you're using the AirMagnet survey tool, or even running reports."

"Hardware is unreliable. It's already crashed on me several times."

"Ease of updating, automated updating. Basically, based on the unit right now, maybe get it to be a little bit smaller, lighter."

"I would like a built-in tap feature which doesn't interfere with the network, and it allows you to see what is happening there."

"The reports I got back from the guys I sent to training said the guy spent more time telling stories, war stories and that type, rather than actual training about the product."

"With the cost it's hard to justify having more than one in our school."

"It's bulky; it's a big tablet. The physical dimensions need to change a little bit; it needs to be more portable."

"We use the tablet version, and I'd like it to have a longer battery."

More OptiView XG [EOL] cons

Pricing and Cost Advice

"The price of Cisco Data Center Network Manager is expensive compared to other vendors on the market."

"I would say that the pricing offers great value for the money."

"On average, Data Center Network Manager's pricing isn't too costly unless you choose a premier license."

"When we purchase a Nexus box, the MDS CM license comes with it."

"The product is licensed with contracts that work on a yearly basis rather than a monthly model."

"We usually opt for a yearly plan, commonly for three or five years upfront. Some customers may not utilize all the features included in the product, and this can lead to them paying for functionalities they don't need."

"The solution is very expensive."

"The tool is always expensive, but their service, product quality, and support are good. We're happy with it, but it's still an expensive solution. There are cheaper alternatives but no similar platform across all domains."

"Its price was a bit excessive. The device that I had died. It is under warranty, and they want $20,000 for another one. I just don't want to spend that kind of money, so I'm trying to find an alternate solution. They have annual maintenance on it, which probably was 10% a year, so it all starts to add up."
