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.

Cloud storage and email have supported our association but usability and search still need work
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. I didn't really feel there was anywhere I could go if I had questions in order to live chat or reach out to someone; if that exists, it wasn't made apparent to me. Being able to search keywords and having what you're looking for come up, whether it's an email or in the drive, could definitely be improved, and making it work better with cell phones and improving the setup to be more user-friendly would be helpful.

Quotes from Members

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

Pros

"The initial setup is very good, not complex at all."
"Dell support is the best."
"Dell PowerEdge Rack Servers are very good for our solution. It is the best option on the market and the best solution so far. I would rate Dell PowerEdge Rack Servers a ten out of ten."
"When we moved to PowerEdge Rack Servers, we converted all the physical legacy servers to the virtualized server, reducing operational cost, maintenance, and improving availability of the environment by 30 to 40%, while increasing functionality from 92 to 93% up to 98 to 99%."
"I would evaluate the support from Dell as exceptional."
"We haven't faced any problems with the power supplies. The consumption of power is robust. We still have slots for the new hard discs for availability and upgrading RAM, but the machine itself has been working nonstop for ten years."
"Using Dell PowerEdge servers has absolutely helped reduce unplanned production downtime; before we had them, we experienced unplanned downtime approximately once every two months, and after we implemented Dell PowerEdge R-Series, there has not been any downtime, resulting in a 100% reduction of unplanned downtime from hardware."
"The most valuable feature, when I compare Dell PowerEdge Rack Servers with other brands available, is the price versus performance, as I get more for what I pay, and mostly, we use this for our CAD workloads."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"The initial setup isn't too difficult."
"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."
"It created a reusable library with OpenStack features."
"There are many services that can be directly used which are not available in VMware."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"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."
 

Cons

"Dell can improve or speed up the deployment process with more intuitive dashboards, a more intuitive installing process, and maybe more detailed guides that can help the end user to install and implement their servers and racks."
"The only aspect that could be improved is the price. The product is extremely good, so it is always priced high."
"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."
"The product must provide more options to add GPUs to the machines."
"My experience with pricing, setup cost, and licensing has been positive until recently, but the prices increased significantly."
"The way we can manage the environment through the solution's GUI could be improved."
"We realize that the power supply may be a weak link when running high loads constantly."
"We have storage and would like to manage more backups without adding extra storage devices. Maybe it's already there. I need to look at it more."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"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."
"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."
"The line migration is a problem."
"It could use more examples in different languages (API use cases).​"
"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."
"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."
 

Pricing and Cost Advice

"The product's pricing is not good."
"The more complex the server requirements, the more expensive it gets."
"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."
"Dell is priced better than alternative solutions."
"We weren't paying very much, but it was at the end of the lifecycle. We are now using the VxRail hyper-converged infrastructure, and the pricing was very similar for the same amount of power but with easier automation."
"The pricing is very good because there are a lot of types of PowerEdge Rack Servers. You have the R540, R640, and R740. The prices are very scalable through the specific server, e.g., small businesses can take the R640 while large businesses can take the R740 or R840. Thus, Dell technologies touch on every organization."
"The tool's pricing is very good."
"They are fairly priced."
"The pricing is low."
"I use it as an open-source tool."
