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.
TAIYAB HASAN - PeerSpot reviewer
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."
"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."
"When compared with SolarWinds, it is more user-friendly, and tasks can be completed more quickly."
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"You're building a scalable solution, a secure solution, and a stable end-to-end solution; these are the main measurable benefits VMware NSX provides to the users."
"This is the most scalable product of its type."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."
"I rate the scalability as ten out of ten."
"To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product."
"They have a lot of support and specialists who can meet with the customer."
 

Cons

"Level one administration task can be defined in Micro Focus Network Automation but it could be more simplified."
"Compatibility of the devices needs to be enhanced, as it seems to be limited."
"The tool performs slowly."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"It lacks full knowledge of physical side of the network topology."
"It was stable for one year, there was no impact. In the last two months, we had two big incidents."
"VMware NSX can improve the migration tools from the older environments to the new environment. For example, the NSX-V has become a legacy solution, it's out of support, but customers are able to keep using it. For migration purposes, it's better for them to provide a proper tool. It will be easy to migrate from an old environment to a new one."
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds."
 

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."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"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."
"The licensing fees are expensive and we pay on a yearly basis."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The price of VMware NSX is reasonable."
"The price of VMware NSX is very good compared to other solutions."
"We are using the free version of the solution."
"The price of this product is too high."
