Doesn't have many proprietary protocols but some models have stability issues
We had stability issues with Alcatel-Lucent OmniSwitch Ethernet Switches 6250. One issue is with licensing. When migrating from TDM to VoIP/ToIP solutions integrated on the same architecture, Alcatel-Lucent OmniSwitch Ethernet Switches don't have the same skill level or follow the same development path as companies like Cisco. They started integrating these solutions later, which is why there's a noticeable difference in advancement. Their main focus has been IP PBX solutions like OXO and OXE. They developed their IP environment and switches later, but not as deeply as other vendors. For example, they use Aruba access points and controllers for wireless solutions rather than developing their own portfolio. A specific challenge I've faced is with access points. Due to country code restrictions, the model sold in one region (like Europe) may not work properly in another. This affects channels and features related to the electronic environment specific to each country. To resolve this issue, I've had to reconfigure access points with the correct country code. The solution uses basic protocols. It doesn't have proprietary features like Cisco's EIGRP or advanced BGP features; it's based on standard protocols.

"The most valuable feature for me is the stability of the switches."
"OmniSwitch Ethernet Switches' best features are it's easy to deploy, manage, and maintain, with services coming through one vendor."
"The solution doesn't have many proprietary protocols like Cisco's. It mainly uses standard protocols like VRRP (similar to Cisco's HSRP), Spanning Tree, and Rapid Spanning Tree, which can sometimes cause integration issues."
"The most valuable feature for me is the stability of the switches."
"It's easy to extend the stack, We don't use the smaller switches, but it's going well for the rest."
"Enables direct access to clusters."
"It is a very easy-to-use product."
"The most valuable features of Mellanox Switches are the powerful hardware and the software is open. They're using Linux operating system. You can do and install many things, and it performs well."
"The most valuable features of this solution are its functionality."
"The biggest advantage is that the vendor is the only one providing no-drop traffic."
"The tool is very configurable because it runs on a Linux operating system."
"The most valuable features of Mellanox Switches are the size, power consumption, and the vast amount of features."
"From what I've been told, a valuable feature of Mellanox switches is they're quite user-friendly."
 

Cons

"I could see them possibly creating a more intuitive software. It's very user-friendly, but there are some things that aren't very intuitive when programming the switches."
"technical support response time is sometimes very slow."
"The product would be better if it were completely compatible with other switching products."
"The network connection should be improved."
"The commands for the switches could be easier as I find them more complex compared to those of Cisco."
"OmniSwitch Ethernet Switches would be improved if cloud-based technology was provided in the Gulf region."
"We had stability issues with Alcatel-Lucent OmniSwitch Ethernet Switches 6250. One issue is with licensing. When migrating from TDM to VoIP/ToIP solutions integrated on the same architecture, Alcatel-Lucent OmniSwitch Ethernet Switches don't have the same skill level or follow the same development path as companies like Cisco. They started integrating these solutions later, which is why there's a noticeable difference in advancement."
"There needs to be better integration with the interface."
"Mellanox Switches were easier before Nvidia bought Mellanox and then their new version of the operating system changed. They started with Ennui, and now they only use Linux. If they returned to their previous CLI it would be a good option for starters. The new CLI is more difficult to use but more powerful than the older one. It has its advantages."
"The configuration is a bit different from Cisco, and therefore, for me at least, there's a bit of a learning curve."
"Sometimes, it can have some bugs from the past if I am an old user. However, it is stable now."
"If you compare this solution with Cisco, utilization in Cisco is more popular and it is more friendly."
"The scalability is working fine at the moment, but there's always room for improvement. As of right now, I don't know of any improvements to suggest."
"Mellanox Switches could improve by adding some features that can make it easier for integrating the switches in some managing and monitoring platforms, such as Elastic or similar software for monitoring data with the data center in a more holistic way."
 

Pricing and Cost Advice

"The pricing is reasonable compared to Aruba and HPE."
"The licensing for OmniSwitch Ethernet Switches is a one-time purchase with no additional costs."
"It is an expensive solution."
"Pricing is cheap compared to other vendors. When we benchmark the tool against Meraki, Cisco, and others, it is usually more affordable."
"The price of Mellanox Switches is reasonable compared to other solutions. The price and quality ratio was very good. There is a one-time license purchase that is needed."
"The pricing is very competitive. The licensing costs are fine."
"It's an open-source solution."
"There is a license to use the switch ports of Mellanox Switches."
