Systems Administrator at Lico Innovations B.v.
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.

Quotes from Members

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

Pros

"They are very stable. They are rock solid. I am happy with them."
"These servers have maintained a level of uptime that is needed by the business and that satisfies the business owners and makes them very happy."
"The solution is easy to use and has good performance."
"All the customers that I have implemented PowerEdge for are very happy and like the performance."
"I would describe my experience with Dell's support for PowerEdge solutions as great, as we had to get a motherboard replaced, and the replacement part arrived the next business day, which was impressive."
"The most valuable features are resiliency, reliability, easy installation, maintenance, and compatibility with other systems or servers."
"They have superior customer support compared to Supermicro, which does not cater to enterprise-level needs."
"The real advantage to Dell when I look at some of the other competitors is the support."
"It created a reusable library with OpenStack features."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"Customer Service: Top. Technical Support: Top"
"Administrators are very comfortable with the functionality and services OpenStack offers."
"There are many services that can be directly used which are not available in VMware."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"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."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
 

Cons

"Although PowerEdge's price is high."
"They should improve the centralized management interface. When you are going to deploy something, for example, VMware or RedHat, it should be easier to deploy a lot of servers. Now you have to do one at a time."
"There are certain aspects, features, and functionality on the motherboard that need improvement."
"Its price could be better."
"It would be nice if the rack servers had an HCI solution as an option."
"Its pricing could be better."
"There is room for improvement in certain aspects of the deployment process as it is a bit complex."
"I would like to see the pricing improved."
"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."
"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."
"It should have a single dashboard for cloud management and on-premises systems"
"The deployment process could be easy."
"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 seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The pricing of Rackspace is quite high in the Vietnam market."
"So for the main stability, there have been a couple of issues that I've experienced."
 

Pricing and Cost Advice

"Compared to other vendors, the prices are much lower."
"We have not compared them with others. The price is okay, but they can always be a little bit cheaper."
"The main reason I choose Dell there is cost. Dell is cheaper than HPE. Why would I want to pay a premium for an HPE product when I'm getting the same amount of support, the same amount of data protection, and the same amount of performance from Dell?"
"The server is a one-time purchase, but the support is on a subscription basis."
"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."
"PowerEdge is not a cheap product. It's a quality product, but there is always competition. If you want to buy a server, you need an operating system, and most of it is Microsoft. A bundled solution costs less than a separate operating system and hardware."
"Dell's solution was cheaper than HP's solution."
"PowerEdge pricing is equivalent to that of all the others in the market."
"I use it as an open-source tool."
"The pricing is low."
