Supports flexible hosting needs through seamless upgradability and strong monitoring capabilities
The most valuable features of Dell PowerEdge R-Series for me are the feature richness and the upgradability. I really love the way that it is so dynamically applicable for every situation, and they manage to have an all-in-one solution for every single situation. Dell PowerEdge has supported the growth and operational success of my company through its great compute power and price-to-performance ratio. Every time Dell is at the top of its game for us, and there is just no other brand for us that is able to reach that kind of price-to-performance ratio. Dell PowerEdge R-Series has features that specifically cater to the needs of my small company, such as iDRAC. The iDRAC system is a complete feature set for managing servers and hardware technically and monitoring-wise. It really fits in our system and our ecosystem, and monitoring-wise, it is excellent. They have all these sensors available via different protocols and end points, which I love, and the ability to manage and control everything via the iDRAC interface is just a welcome bonus. In our use case, Dell PowerEdge R-Series is very flexible. It is another computer which helps a lot because of the durability over time. They keep running, making scalability for getting more of those resources in our environment so easy.

Private cloud control has deepened my DevOps automation and strengthened security practices
For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners. We can also work on improving the user interface; the Horizon dashboard is functional, but compared to AWS, Azure, or Google Cloud, the UI feels somewhat dated. A more modern, intuitive interface with better navigation would enhance the overall user experience, especially for new users. Improving the documentation, including more real-world deployment examples, troubleshooting guides, and architecture best practices, would make onboarding much easier. Faster upgrades would also help; Rackspace OpenStack upgrades can sometimes be complex, so simplifying the upgrade process and minimizing downtime would assist organizations in maintaining their environments more easily. Additionally, improving monitoring capabilities would be beneficial, with advanced monitoring and analytics dashboards providing administrators deeper visibility into performance, capacity, and potential issues without relying heavily on third-party tools. Adding more managed services, similar to what public cloud providers offer, could reduce operational overhead while still allowing customers to retain the flexibility of a private cloud. Lastly, integrating AI could be valuable, with AI-driven recommendations for capacity planning, security monitoring, and automated troubleshooting improving platform management.

Pros

"PowerEdge servers powered by Intel are highly stable; some of them have stayed on for two years without ever rebooting."

"The rapid rail system is valuable. We have staff working at night to perform installations, and the nature of our business involves real-time transactions with changes made outside of regular hours."
"It's required for our business. Dell PowerEdge Rack Servers benefit our organization as we build satellites and use images from Earth to check the planet's health and constellation for telecommunication purposes."
"The most useful opinion about Rackspace OpenStack is that it is very flexible, first of all, and the most important feature is that it is feature-rich."
"The documentation was plentiful and very helpful.​"

Cons

"Its price could be better."
"There can be more visibility on the equipment remotely."
"Different types of applications that are now trendy in the market, like AI, are still big topics that are not mapped correctly in the server and storage environment. Knowing those kinds of activities and definitions will help us more to position these kinds of servers for the client."
"I would increase the life cycle management and those life cycle management tools."
"When interacting with customer support, it defaults to Arabic because of our region. However, most of the experts here are not familiar with Arabic. We would like English as an alternative language for easy interaction."
"On the negative side, I must say that the price of Dell PowerEdge R-Series is an issue."
"The pricing can be better. These are expensive machines."
"The rate controller interface is difficult to get to without installing additional software. It would be helpful if they had preinstalled software to make that easily accessible."

"It could use more examples in different languages (API use cases).​"
"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."
"The pricing of Rackspace is quite high in the Vietnam market."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"So for the main stability, there have been a couple of issues that I've experienced."
"We are moving from Rackspace OpenStack to CloudStack due to the requirement of human resources and technicality. There are lots of moving parts in Rackspace OpenStack."

"The pricing and licensing are fair."
