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

"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 solution delivers what it promises. You look at the specs and it delivers them."

"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."

"From my point of view, the biggest return on investment when using this product is the reliability and low downtime that I have had with them, the ease of management, and automation."

"The solution's stability is good...The solution's scalability is good."

"The stability is good, it also lasts a relatively long time, our customers are typically looking for something that will hold up for about five years, and this solution does that, as it's not buggy, there aren't glitches, and it doesn't crash or break down."

"The IDRAC is a selling point. It gives you an easy way to manage the system, services, and installation."

"Dell PowerEdge R-Series scales with the growing needs of my company as we add more servers and expand the clusters, making the process straightforward."

More Dell PowerEdge R-Series pros

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

"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."

"OpenStack allowed for mass uploading of images to Akamai cloud services."

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

"It created a reusable library with OpenStack features."

"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."

"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."

"The solution is stable."

More Rackspace OpenStack pros

Cons

"The physical design could be improved as it is heavy and quite large when racked."

"They should reduce its size. Because the CPU power is more now, they can reduce the size of the servers. Currently, we have a 2U server. If possible, they can make a 1U server."

"The grade store disks sometimes break, indicating an area for improvement in longevity and reliability. They need to improve the durability of the disks."

"I would improve the Dell PowerEdge Rack Servers by enhancing the GUI and providing a better hands-on experience for quick fixes on the servers, as most of the work is done by a vendor coming in to fix the systems."

"Lately, we feel that we need an improvement in our servers. Surprisingly, we have seen some servers here that do meet these characteristics. They are slightly smaller servers."

"There might be room for improvement in terms of efficiency, particularly with PowerEdge servers."

"System security can be improved. They can add more power and security for ESXi version 7."

"I realized during the session that we had a lot of back and forth before we finally arrived at the solutions."

More Dell PowerEdge R-Series cons

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

"The line migration is a problem."

"I cannot comment comprehensively on how Rackspace OpenStack can be improved, as I do not find that much difference; however, some areas can be improved, such as support for OEMs deploying highly specialized real-time telecom and media workloads."

"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."

"The pricing of Rackspace is quite high in the Vietnam market."

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

"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."

More Rackspace OpenStack cons

Pricing and Cost Advice

"We have a strong agreement in place with our parent company, that typically ensures favorable pricing terms for us, although occasionally we may need to negotiate with Dell representatives for further discounts to provide competitive pricing to our customers."

"We do use Dell's OpenManage console. It is easy to use this console for lifecycle management or PowerEdge servers."

"The more complex the server requirements, the more expensive it gets."

"I don't see any issues with respect to licensing. It's power-efficient, so it's beneficial to the customers price-wise. There are no costs in addition to the standard licensing fee."

"We have a contract with the OEM of the equipment for licenses, so we possess all OEM licenses for the Dell software. We have licenses for Linux and VMware software, with a special price and an annual contract for updates of Linux and VMware. Additionally, we have an Oracle database on the Dell PowerEdge Rack Servers."

"The overall pricing and licensing are fair according to the market."

"You can't have computed performance without using more power. That said, when I consider the power consumption and performance of the MX740c, depending on how much memory you install on each blade, you get the best bang for your buck."

"The high cost of Dell PowerEdge Rack Server licenses is attributed to the pre-installed Windows Server operating system from Microsoft."

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

"The pricing is low."
