As a supplier of fabric networking, Extreme offers a portfolio of Ethernet and IP fabric solutions. Whether to transform a campus, data center, metro, or WAN, Extreme Networks Wired Access - Switches (ExtremeSwitching) fabric technologies aim to ensure a faster, more flexible, and more secure foundation for businesses.
Cisco FabricPath seems to be well suited for larger datacenters where you need the scalability and flexibility that's provided. We've been able to provide our customers with much more bandwidth than they previously had throughout our datacenter and with applications generating much more east/west traffic now rather than large volumes of north/south traffic FabricPath and the nexus switches have given us the ability to provide our customers with the bandwidth that's needed to serve today's applications.
It works very well in environments where you need to stack multiple switches together for additional ports, while providing a single management IP to configure vs configuring numerous switches independently. Their vast portfolio has products that would be well suited for access switches, core switches, and distribution switches. For core/distribution, I would not use their cloud management platform however due to its limitations in options.
It's been fairly easy for people to learn and work with.
It has simplified network administration by utilizing Fabric Extenders which are all configured from the same switch and treated as an extension of the switch rather than as a separate entity.
There hasn't been a single problem with the code or hardware that hasn't been resolved in a timely fashion. You get technicians who know the product and who will work with you to get things fixed. That being said, I never ran into a problem with Cisco tech support either. I love that both groups were willing to teach me as they fixed things.
In comparison to Cisco ACI, Cisco Catalyst, and Juniper EX Switches the Nexus switches have stood their ground and we've been fairly happy with them. I like that similar to Cisco's ACI and the Juniper EX switches that I've worked with I can manage multiple chassis from one place. ACI can do this on a much larger scale though. I think Juniper limited the number of devices in a single virtual chassis to 10 or less depending on the device type. ACI can do a few hundred leafs plus their fabric extenders so if you're looking for one place to manage all your devices it can scale well beyond either the Cisco FP or Juniper EX series switches, but it also has a much steeper learning curve and completely different interface. The loop prevention built into FP has been a great improvement vs our old Catalyst switches.
I found Aruba equipment to be more expensive than Extreme [Ethernet Switches] and I just was not sold that they would perform better. In my opinion, you are paying a premium for the HPE Aruba brand. We've been using Extreme back when they were called Enterasys. They were pushing network boundaries for years even before Extreme bought them. I think Extreme [Ethernet Switches] are a better quality switch.
FabricPath is easy enough to learn that the adoption on the team has been fairly quick. This allows us to quickly troubleshoot and allows us to meet and beat SLAs that demand we maintain 99.99%+ uptime for our paying customers.
Extreme [Ethernet Switches] have a long-life. You can easily get 7 years in main production life depending on when you buy in the product life-cycle.
Extreme [Ethernet Switches] are expensive, no doubt, but we also don't have "weird" network problems or other issues with the network randomly going down.
If you use fabric connect switches then the ease of managing many switches is of no concern.
