HPE Aruba Networking Switches vs. OpenText Network Node Manager i (NNMi)

These devices are rock solid, you will se them up once and not have to mess with them for years. They are work horses that don't die. We use them in an office environment and have only ever had 1 fail due to a PSU issue, we got a replacement next day and it's been working great.

Well-suited for large-scale deployment without needing more servers. Linux installation is quite stable, and Polling of a large number of devices is well managed. Less suited to Network Observability scenarios or cloud network monitoring.

• REST API capability
• Wired & Wireless 802.1x configuration easiness
• Wireless Access Points (APs) zero touch provisioning
• Its high-end family (running the AOS-CX firmware) supports a virtualization technology called VSX (Virtual Switching Extension) which allows 2 switches to present itself as one virtualized switch under Layer 2, and as 2 separate routers under Layer 3; thereby providing high availability.

• I have had issues finding monitoring software that natively supports Provision/Aruba OS. Most are designed primarily with Cisco in mind.
• HPE/Aruba switches have historically had issues with corrupt flash. This seems to be less common in more recent models.
• HPE/Aruba's switching portfolio can be confusing. Some models run on the Aruba OS while some others run on Comware. There is some overlap in these model lines so at times is can be tough to tell which switch is right.

I have not had that many issues with these products. Aruba Central has been really helpful. The Integration Capabilities allows us to use Clearpass . For individuals new to enterprise-grade networking, there can still be a learning curve associated with understanding the concepts and the specifics of the Aruba configuration.

NNMi's user interface is described as well-designed and intuitive, making it easy for users to navigate and perform tasks quickly, thereby enhancing the overall user experience. The system offers a powerful network discovery mechanism that maps out your network's physical and virtual topology, enabling you to visualize connections between devices and identify potential issues. Fault monitoring is at its best. NNMi provides a unified environment for viewing faults, availability, and performance data, consolidating essential information into a single platform.

HPE Support is very easy to reach. A knowledgable rep can be reached in a few minutes. After some basic troubleshooting if the failure is due to hardware I can receive a replacement within a day or even in a few hours.

Support is long and arduous and often are unable to help resolve the issue. We often have to do escalations or duty manager to get things moved. Even with a technical account manager, we do not see much improvement from a support point of view. This is an area where Micro Focus has a lot of improvement to do.

We used to have a lot of Cisco switches which are great, but
the support contracts and other expenses mount up quickly; one of the main
reasons for switching to HP for networking was the cost, but the hardware and
software have gotten so much better over the years.

I can’t see us changing network hardware unless the price increases dramatically.

Even though there are many products in the market such as from Solarwinds, CA Spectrum (no DX Spectrum), PRTG that offers similar or even with more flexibility the fault and performance monitoring still Micro Focus is a very nice tool when it comes to Scalability and Stability with all necessary monitoring coverage. There is no external database required and hence less issues with integration.

• I really like the idea of paying for the switches one time and just pay for support going forward. The prices are on the high end but I think it is worth it. I wish they would include all the features in one go so we would not have to pay for every new feature.

• HP NNM is very good at producing root cause analysis. MTTR is reduced with NNM.
