HPE Networking Switches (formerly branded HP ProCurve) were Hewlett-Packard Enterprise's network / LAN switching option, that has been discontinued in favor of the company's Aruba switches.
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.
HPE Networking Switches are great for most any scenario. They are great with low network load and also high network load. They are not exactly the cheapest solution, so they aren't suited for budget conscious users. They are made to work 24/7 with no interruptions, and they have lived up to that promise for us.
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.
The Enterprise management software always seemed less intuitive than the default software.
More of the parts could be supported across a wider variety of models.
Add-on modules should be cheaper than buying a new switch with modules already installed. So they could really do to serve their customers better with pricing options.
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.
HP is a Great balance of everything you need, from cost, quality, and manageability. I have worked with Cisco, Dell, and Ubiquiti, as well as many other brands. Each come with their own Pros and Cons, but are all good products. In the end, I go with HP because the product has never done me wrong. Perception is everything. Downtime makes people question the credibility of the IT managing the systems. HP has never put me in a bad spot where the quality of IT is questioned.
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.
