Allows to upload necessary firmware to your device and perform the upgrade
With OpenText Network Automation, firmware can be uploaded for specific devices. If you need to upgrade a device, you can use this tool, though it may not apply to all devices. The software allows you to upload the necessary firmware to your device and perform the upgrade. Additionally, it enables you to check multiple devices for specific configurations and automates the search process and the configuration of multiple devices.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

"Pushing the network configuration to bulk devices. This saves a considerable amount of time that the engineer spends in pushing the network configuration."
"With OpenText Network Automation, firmware can be uploaded for specific devices. If you need to upgrade a device, you can use this tool, though it may not apply to all devices."
"Micro Focus tools are mature tools, that are well developed."

Cons

"It should be more adapted to the physical side of network topology in order to prevent unavailability."
"The vendor should integrate a basic load balancer in future versions"
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"However, they should provide better documentation."
