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.

Quotes from Members

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

Pros

"The availability is excellent."

"Dell PowerEdge servers are powerful. They don't break, and I love that. In my career of over 30 years now, all the Dell servers we've ever used out of the box have never broken."

"Using PowerEdge rack servers has allowed us to use less space. Previously, we used the regular servers, but PowerEdge rack servers take up less space and are easier to handle."

"The user interface is very simple, and the support team is always happy to answer any questions we have. They are very easy to contact."

"Using Dell PowerEdge R-Series servers has helped reduce the total cost of ownership because we know what to plan for when doing a server update and we know what to get in order with newer processors and storage."

"I rate Dell PowerEdge Rack Servers as a nine out of ten overall."

"Dell PowerEdge servers have absolutely helped to reduce unplanned production downtime, with incredible reliability and uptime that keeps customers coming back, even when they want to do a refresh, because they know it is a reliable system."

"The solutions accelerated GPUs have helped to support demanding workloads and to reduce data processing time in our organization."

More Dell PowerEdge R-Series pros

"Administrators are very comfortable with the functionality and services OpenStack offers."

"It created a reusable library with OpenStack features."

"Rackspace OpenStack impacted my organization positively in that the drive helped me keep files in an organized folder, and obviously we needed email addresses to be able to communicate with each other and for outsiders to be able to email us."

"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."

"There are many services that can be directly used which are not available in VMware."

"The documentation was plentiful and very helpful."

"The open-source nature of OpenStack provides significant value."

"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."

More Rackspace OpenStack pros

Cons

"The pricing of Dell PowerEdge Rack Servers has been a little problematic. It was sticker shock with our most recent purchase compared to the previous one, and there's a gap in pricing at our current level because what we do isn't very compute-intensive, resulting in a mismatch where we fit into an in-between category without an exact solution available."

"The performance could be a bit better."

"Dell PowerEdge Rack Servers have higher hardware costs compared to HPE ProLiant servers, which are cheaper."

"Non-vendor-specific things could benefit Dell PowerEdge R-Series. Dell has a lot of OEM material, obviously, because it is an OEM provider, but it could benefit from more AMD, more ARM, and more across the line."

"The solution could still use some more analytics."

"The choice of CPUs, RAM configuration, and modifications is very large, partly even a bit too large, because I sometimes get lost in the configuration options, but nothing negative really stands out to me at this point."

"I do not have any input as such. There can be a bit more expansive AI portfolio, but I have not worked on any AI projects with Dell, so I might not be up to date in knowledge."

"There are a lot of data platforms around, but it would be helpful if we could perform some basic data operations on the server so we don't need an extra vendor. Azure is their Microsoft Cloud solution, and they collaborate with data companies like Databricks. We are also on the cloud and work with Databricks, but they could add some basic features so an enterprise doesn't need to go for extra Databricks to do their data things."

More Dell PowerEdge R-Series cons

"Rackspace OpenStack can be improved because it wasn't clear that you have to cancel 30 days before; otherwise they charge you for the month."

"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."

"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."

"OpenStack is difficult for the novice in terms of beginning to use cloud tools."

"It could use more examples in different languages (API use cases)."

"The line migration is a problem."

"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."

More Rackspace OpenStack cons

Pricing and Cost Advice

"The licensing comes with a warranty."

"The main reason I choose Dell there is cost. Dell is cheaper than HPE. Why would I want to pay a premium for an HPE product when I'm getting the same amount of support, the same amount of data protection, and the same amount of performance from Dell?"

"The pricing is very competitive."

"The pricing is great; very competitive. That's the reason we bought hundreds of them."

"The cost structure associated with Dell PowerEdge Rack Servers presents itself as a potential point of contention for budget-conscious consumers, as it could be more strategically positioned to compete within the broader marketplace."

"Dell is priced better than alternative solutions."

"It's a one-time licensing fee for the device and we pay a quota per year for the support."

More Dell PowerEdge R-Series pricing and cost advice

"The pricing is low."

"I use it as an open-source tool."
