Local servers have delivered long-term ERP and virtualization performance while reducing cloud costs
In terms of improving Dell PowerEdge R-Series, to be honest, the product has so many options that I find it very difficult to improve it in terms of product itself. Of course, there will always be some technological evolution and new components, but what the product offers in each generation, and I've already followed five or six generations of Dell PowerEdge from generation 11 up to generation 17, it has always kept pace with technological innovation. In terms of storage, it's always extremely in line with what the market is offering. In terms of memory, each new generation always follows the newest RAM trends. Processors also have both AMD and Intel options. I believe the product already has very high maturity. The availability of redundant power supplies and the availability of off-band management via iDRAC are excellent. The product is already extremely solid and reliable. The most I could perhaps say is that sometimes in some operations, I find iDRAC a bit slow, but that's a characteristic of off-band management because performance comes from a separate card that has its own processor and its own memory, so sometimes it's not as fast as I'd expect from the machine itself. Overall, there really isn't much to say because the product is extremely robust and efficient.

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 reliability of its hardware and the support they provide are valuable."
"Dell's customer support is very good, especially since we have premium support for next-day hardware service."
"It's a very user-friendly solution."
"It's helped us reduce unplanned downtime."
"Dell PowerEdge R-Series is basically install and feel at home, so to speak, and I find that really great."
"The ability to manage them all from a central position makes my life a lot easier, and it means I can get a lot more done faster."
"Using Dell PowerEdge R-Series generally helps reduce unplanned production downtime due to their reliability."
"The Dell platform works very well, we are very happy with it, and if price isn't a concern, I would recommend Dell PowerEdge Rack Servers."
"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."
"Rackspace OpenStack has positively impacted my organization by bringing us much closer to our customers based on the supportability this platform provides, and it has unique features which are very useful for our customers."
"Customer Service: Top. Technical Support: Top"
"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."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
 

Cons

"There are no items I want to improve on Dell PowerEdge R-Series; maybe just a discount."
"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."
"In terms of storage, bigger storage capacity for Dell PowerEdge R-Series would be an improvement."
"Its pricing could be better."
"The price is acceptable but could be improved."
"Dell PowerEdge R-Series does not help us grow the company or grow the work."
"They could make the service tags larger as I get older."
"The GUI could be improved. I primarily work with the command line, which enables you to do many things faster."
"As a beginner, I find some difficulties in understanding Rackspace OpenStack, as it can be complex without a foundational grasp of cloud and networking concepts."
"The pricing of Rackspace is quite high in the Vietnam market."
"In terms of what needs to be improved, I would say the support. Rackspace might have some good support but the open source OpenStack doesn't have support because there are too many versions coming and too many people are customizing it."
"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."
"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 seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The pricing for Rackspace OpenStack is sometimes not competitive according to other market products, as sometimes the price is high for some components like Advanced Cluster Management (ACM) and Advanced Cluster Security, which are very costly add-ons, not the main license."
"It could use more examples in different languages (API use cases).​"
 

Pricing and Cost Advice

"It is expensive. The price needs to be more competitive. Additional licenses are required to enable some of the features for scalability."
"Dell is priced better than alternative solutions."
"This is an expensive solution."
"The licensing comes with a warranty."
"I don't know about the product's licensing part. Price-wise, it is an okay product. I believe that the cheaper the better, but I think that the product's price is okay."
"At present, the pricing seems a bit high for us."
"The pricing is fair enough."
"When you compare public cloud solutions to PowerEdge in terms of cost, initially the cost of Dell servers or Dell technology was really high. However, right now it's on par or, maybe, even cheaper when we use Dell hardware. If we don't swap it out in three years and if we stretch it to four or five years, then we can get even more of an ROI versus cloud cost."
"The pricing is low."
"I use it as an open-source tool."
