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 scalability of Dell PowerEdge Rack Servers is excellent."
"The best feature of Dell PowerEdge R-Series is not just one aspect, the entire product is very robust, we have been using it for many years and we are receiving lots of positive feedback from our customers."
"We actually have not had any failures in the last 7 years regarding availability."
"The ease of installation is valuable. The physical side of installation is quite intuitive and has got better by leaps and bounds. The hardware has always been fantastic, and it has always been reliable."
"Great value for money is definitely provided."
"It's helped us reduce unplanned downtime."
"I would estimate we save two to four hours a week, depending on what's happening, such as if we need to spin up a new server, which would contribute to more time if done the old way."
"We want to ensure that we have 24/7 availability with Dell PowerEdge R-Series, and we have pretty much had that with the servers over the years."
"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."
"Rackspace OpenStack positively impacts my organization by making processes easier since I do not need to manage all servers manually because it efficiently manages server operations and maintains proper data, which saves time."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"In my experience, Rackspace OpenStack delivered a stable, flexible, and reliable private cloud environment."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"The solution is stable."
"Customer Service: Top. Technical Support: Top"
"There are many services that can be directly used which are not available in VMware."
 

Cons

"I do not have any input. My servers are quite old. Newer systems are more sustainable in terms of energy consumption. I need to consider more power-saving and sustainable options."
"After purchasing the product, customers have not been getting the support that they need in the early stages of getting set up."
"The only aspect that might raise it to a ten is the response time for quote turnaround; it used to be one day, however, it now seems to take longer since the merger of Dell and EMC."
"I would like enhanced latitude in the machine assembly process."
"If I rated the support two years ago, it would have been a high eight or maybe a nine; in the last six months, it has likely dropped to a six or seven out of ten due to a lot of churn in Dell, particularly with their sales force and engineering teams."
"Dell PowerEdge R-Series can be improved on the cost if they can lower the price, and of course, more security."
"The pricing structure could be improved."
"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."
"The pricing of Rackspace is quite high in the Vietnam market."
"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."
"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."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"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."
"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."
"The line migration is a problem."
"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."
 

Pricing and Cost Advice

"They are affordable. Even during our recent procurement, the cost of Dell servers was lower than that of HPE."
"It's abundantly clear that the specific licensing requirements will be dictated by the intricacies of the machinery we deploy."
"PowerEdge pricing is equivalent to that of all the others in the market."
"The pricing for Dell PowerEdge Rack Servers is on par with everything else at the moment."
"I am satisfied with the pricing of the Dell PowerEdge Rack Servers and would rate the cost as seven out of ten, with ten being the best."
"They are fairly priced."
"The cost structure associated with Dell PowerEdge Rack Servers aligns closely with the prevailing norms established within the information technology hardware sector."
"I'd like them to be cheaper, but that's not the world we live in and that's not where the pound is at."
"I use it as an open-source tool."
"The pricing is low."
