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.

Quotes from Members

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

Pros

"Pushing the network configuration to bulk devices. This saves a considerable amount of time that the engineer spends in pushing the network configuration."
"When compared with SolarWinds, it is more user-friendly, and tasks can be completed more quickly."
"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."
"VMware NSX is a very good solution. It's also a scalable solution."
"The Distributed firewall is simple to add to the network and rules are easy to implement."
"NSX can reduce costs and has good service. It is easy for you and your users to use."
"The solution's customer service is good."
"The most valuable features of VMware NSX are the tight integration with the VMware Hypervisor natively and the management console. We have a lot of other integrations where you are able to see the virtual machine's end-to-end visibility."
"You can easily integrate this with other VMware products. It is a robust solution."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"The most valuable feature of VMware NSX is the high bandwidth."
 

Cons

"The tool performs slowly."
"Compatibility of the devices needs to be enhanced, as it seems to be limited."
"Level one administration task can be defined in Micro Focus Network Automation but it could be more simplified."
"I would rate NSX's stability eight out of ten - there's room for improvement."
"The feature it can improve is essentially application-based load balancing with intelligent load distribution for applications that require redundancy and high availability."
"Lacks integration with other solutions."
"The scalability is not perfect."
"The integration with other brands is not the best."
"The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of knowledge."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
"The solution could benefit from improvements in its pricing and scalability."
 

Pricing and Cost Advice

"Pricing is reasonable, but if you compare it with other network Operation Management tools that are available on the market, it's expensive."
"The cost of the solution is a bit high."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"I would rate the pricing of VMware NSX as seven out of ten"
"The solution is free and the price for the support can be expensive."
"The solution is very expensive."
"There is a license required for this solution, we pay annually."
"The price is pretty high."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
