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 performance of Dell PowerEdge Rack Servers is very good."
"This is a quality product that can be customized for our clients."
"What we like the most is the stability, because without shutdowns our VMs and servers are up and running fine."
"The product is very stable."
"Overall, I would rate Dell PowerEdge Rack Servers a ten out of ten."
"The solution is a great service; they do their job and require minimal effort from my side as a system engineer, with very few errors or malfunctions."
"The best features of the Dell PowerEdge Rack Servers are the service, the availability of the equipment, and the relational price quality."
"The Xeon CPU makes the system work very well and fast. I like this type of CPU. It has helped to improve the performance of targeted workloads by 70%."
"There are many services that can be directly used which are not available in VMware."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"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."
"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."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
 

Cons

"I wish that Dell had a competitive product to the HPE MicroServer because if they did, I would buy them, not in their hundreds, but certainly in their tens, especially in my capacity as an MSP."
"My experience with pricing, setup cost, and licensing has been positive until recently, but the prices increased significantly."
"Support could be escalated upwards a bit faster for Dell PowerEdge R-Series. It stays too long at the lower support levels before it is passed on to real specialists."
"I have used these servers in a government project along with Nutanix, and there is a security restriction. I do not know if it is from Dell's side or Nutanix's side. From the host, you cannot read the external hard drive data inside a VM."
"I do not any have input as such, but there can be some AI capabilities."
"The physical design could be improved as it is heavy and quite large when racked."
"Customer service receives a rating of eight out of ten. A perfect ten cannot be given because there is always something that can 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."
"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."
"The pricing of Rackspace is quite high in the Vietnam market."
"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 should have a single dashboard for cloud management and on-premises systems"
"It could use more examples in different languages (API use cases).​"
"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 deployment process could be easy."
 

Pricing and Cost Advice

"Dell is somewhat more expensive than HPE."
"The solution’s pricing is competitive with other products."
"It's pretty much on par."
"The price is reasonable. You have to pay if you want quality. When we purchase something, we have to do some market analysis, and I haven't seen a significant difference compared to other solutions."
"They seem to have become more expensive. I've not done a comparison with other vendors recently. If the price increases more, we would need to do a comparison next year just to make sure that we are benchmarking our server purchases correctly."
"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."
"It's a bit of a shock when you have to find the money, but the pricing is very competitive, so I'm happy with that."
"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."
"The pricing is low."
"I use it as an open-source tool."
