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.

"The overall rating for Dell PowerEdge Rack Servers is ten out of ten."
"Dell PowerEdge R-Series demonstrates tremendous robustness, which is one of the main reasons for continued use."

Cons

"Dell PowerEdge R-Series could be improved in the area of the connection with the OpenManage Mobile App, as it hangs a bit sometimes."
"In Pakistan, the vendors or the partners of Dell are not providing a good environment. They need to improve their support and hire partners that have certified support sources."
"Power consumption is probably on everyone's top of mind regarding Dell PowerEdge Rack Servers; they use a lot of power and create a lot of heat. Also, the noise levels are pretty high, though I'm not sure if there's anything that can be done about it."

"There might be room for improvement, especially in the software aspect, such as firmware updates."
"On the negative side, I must say that the price of Dell PowerEdge R-Series is an issue."
"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."
"It should have a single dashboard for cloud management and on-premises systems"

"The deployment process could be easy."
"It could use more examples in different languages (API use cases).​"
"The pricing of Rackspace is quite high in the Vietnam market."
 

Pricing and Cost Advice

"Dell is pretty good. good. I had a conversation with Dell a while ago due to a vendor. We got much better pricing from a competitor. When I looked at another company, Dell called me and asked why am I looking at someone else when they have a distributor. I told them that their pricing was not good, so Dell went back to the distributor, and we got much better pricing"
"It has generally been very competitive. It is not the best, but it is very competitive."
"The pricing and licensing are fair."
"Dell is somewhat more expensive than HPE."
"The pricing is very competitive."
"This solution is reasonably priced and licenses are easy to acquire."
"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."
"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."
"I use it as an open-source tool."
"The pricing is low."
