Migration between data centers has strengthened core connectivity and simplified segmentation

The biggest problems during migration were corporate issues, including dependencies on other devices such as F5, HSMs, and firewalls from Palo Alto. Everything was connected over the core switches, which made this a quite difficult part to manage and to onboard the teams and to understand the impact of the migration. We encountered an issue where we have two data centers, and unknowingly we were configuring the devices with the same VPC number on both devices. By doing that, we were not able to terminate the lease lines over those core switches. According to Cisco, we had to change the VPC number of one of the data center's core switches since they are in a VPC. We are still waiting, and it has been more than five to six years just to change the VPC number and migrate back the lease line. Now we are having cabin switches for the lease line and then the core switch. That VPC number issue was quite surprising for us. However, we have a very frequent issue with Cisco Nexus, particularly with the SFPs. Every time a port or the SFP heats up, it gets faulty. We have almost sixteen Nexus switches per data center. In a year, we experience one or two port issues per annum. We have standard Equinix data centers with standard installations, but somehow the temperature is always maintained and there is no ducting, yet the ports and the SFPs heat up or become faulty. This is a very frequent issue with the SFP-based port.

Ensures reliable operation and consistent performance but lifecycle management need improvement

QFabric simplified our data center network architecture by reducing configuration complexity compared to Cisco devices. It required fewer CLI commands, making configuration quicker and easier, especially for scalable deployments. QFabric improved scalability in our data center by simplifying the addition of new switches to existing configurations. The process was straightforward to manage. Implementing QFabric can affect overall IT infrastructure costs differently based on configuration needs. For small businesses with stable configurations, costs remain unchanged. However, for scalability and expansion, additional configuration and time may increase costs. My advice for those using Juniper is to ensure staff are well-trained and certified in Juniper technologies, such as JNCIA, JNCIS, JNCIP, or JNCIE. With these skills, you can effectively manage and troubleshoot Juniper solutions, minimizing potential issues and maximizing performance. Overall, I would rate Juniper QFabric as a seven out of ten.

Quotes from Members

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

Pros

"From a functional and technical point of view, I would recommend Cisco Nexus to potential users."

"This solution provides our organization with high capacity."

"The solution has improved operations by helping us resolve bottlenecks throughout our infrastructure, as these new products have a much higher throughput that cleans traffic up and makes processes a lot smoother."

"This solution provides our organization with more business continuity and high availability because we can build them in ways with technology, like VPC, to make sure that our network is constantly up and available to our end users."

"It provides a very flexible connection to a server. When you go into history and the VPC, it provides a very flexible connection from it. Once a server goes down I can instruct it easily. So the network actually keeps quality even if onsite it is down."

"The most valuable feature of the solution is network visibility; it touches all of the switches, becomes the core switch, and all of the devices connected to it route towards it so we are able to see all of the devices."

"The most valuable feature of this solution is stability. We have a pretty large campus."

"The integrations are valuable."

More Cisco Nexus pros

"The most valuable feature of QFabric for network performance is its stability."

"The most valuable features of this solution are the fabric backplane having upwards of 160 GB of communication. It is a top-of-the-rack solution where you have your directors sitting in the main area and then you have your nodes expanded out to your multiple cabinets. It has a very good design and could be your server backbone."

"Juniper QFabric has various advantages including scalability, simplicity, performance, and flexibility."

"Technical support is good."

"It's user-friendly."

"The 40 gig backbone InterConneX was valuable for our use case. It is even faster now. QFabric has spine-leaf technology or topology, which basically makes every single hop only one hop away in terms of connecting from one device to another. It is a pretty good and robust solution. It works pretty well in terms of scalability, and their technical support is amazing."

"QFabric supports redundancy and includes all of the enterprise and service provider features that customers would want in data center or service provider network."

"It is a pretty good and robust solution, it works pretty well in terms of scalability, and their technical support is amazing."

More Juniper QFabric pros

Cons

"Documentation is often scant."

"In the next release of the solution, I would like to see varying integration between VRF (Virtual Routing and Forwarding) instances so we can integrate BGB into different VRFs in a more organized way. We have some issues with tunnels and VRFs."

"All solutions are very expensive and not an economy solution."

"One of our switches died last week and we were able to RMA it. Within four hours it arrived on time and worked."

"I really wish that Nexus and iOS commands were more similar than they are different."

"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 flexibility and configuration could be better. It is not as reliable as Catalyst."

"The initial setup was somewhat complex."

More Cisco Nexus cons

"The disruptive upgrade was an issue for us."

"Improvements could be made to QFabric's life cycle management, particularly in maintaining stable versions and extending product support."

"We are quite disappointed in Juniper switches."

"I do not use GUI's very much for switch stacks. I am always in the CLI. However, I do know that Juniper in the past has lacked on their GUI's, but they have been working on it."

"The price for Juniper QFabric could improve."

"It works too much on rebooting and there is some memory leakage."

"The pricing structure could be more budget-friendly."

"They are working on the virtualization of the actual fabric layer. They are moving away from the original spine-leaf design to a different infrastructure. Instead of having three tiers, which was the director of the interconnected nodes, they cut them back, and they still have that kind of structure."

More Juniper QFabric cons

Pricing and Cost Advice

"We have a virtual license."

"Licensing is annual or every three years. We were one of the big customers, and we used to get good prices, but the cost of the support can be improved."

"In most cases, there is a need to secure perpetual licenses to be able to use the product. When I set up the product, there isn't just a one-time cost that is involved."

"I don't like the Smart Licensing models that Cisco uses."

"The subscription model and price could be better."

"I thought that it would be less expensive."

"The licensing fees for this solution are approximately $800,000 USD annually."

"All of our costs including subscription, licensing, and support services are bundled together, and the cost is approximately $100,000 USD per year."

More Cisco Nexus pricing and cost advice

"The price for Juniper QFabric could improve. There are subscription, maintenance, and add-on feature fees."

"The pricing is high and it is possible to find better pricing option solutions on the market, but the licensing model is quite flexible."

"In terms of price, the QFabric solution is going to be probably in the middle of the road for a fabric solution."

"The pricing is high."

"Juniper QFabric is a high-level solution but it could be less expensive."

"The price is relatively high, but it offers an advantage over its competitors by providing better performance and functionality."
