Tom van Mil - PeerSpot reviewer
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

"I appreciate Dell solutions because they are reliable, and we know what we are getting; if we do need support, it is quick."
"The biggest benefit I see from using Dell PowerEdge is the ease of use."
"The most valuable features of Dell PowerEdge Rack Servers are their worldwide support, which is very accessible along with receiving assistance from professionals and specialists, and the continuous innovations that make it an amazing product in this era."
"We like their quality. I have also dealt with HPE and other manufacturers. In terms of service, Dell is optimal."
"I chose Dell PowerEdge R-Series because of the ease of administration, the simplicity, and the continuity of administration over the years."
"Dell PowerEdge has supported the growth and operational success of my company through its great compute power and price-to-performance ratio."
"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."
"Dell PowerEdge Rack Servers are user-friendly."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The documentation was plentiful and very helpful.​"
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The solution is stable."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The initial setup isn't too difficult."
"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."
"Administrators are very comfortable with the functionality and services OpenStack offers."
 

Cons

"The price is very high."
"They need improvement in spare part availability in Argentina, but the servers are very good from a hardware point of view."
"In terms of the iDRAC software, when selecting systems, especially multiple systems to upgrade, there's really no way to confirm that specific systems are selected."
"Maybe on the education side, working with third-party sellers on how easy their products are could probably help."
"The solution could still use some more analytics."
"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."
"I need more transparency on how OpenManage can help me with our company being an SMB. I want more documentation for SMBs regarding Dell PowerEdge Rack Servers."
"I realized during the session that we had a lot of back and forth before we finally arrived at the solutions."
"The pricing of Rackspace is quite high in the Vietnam market."
"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."
"It should have a single dashboard for cloud management and on-premises systems"
"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."
"The line migration is a problem."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The deployment process could be easy."
 

Pricing and Cost Advice

"They are fairly priced."
"The pricing is very competitive."
"It's a one-time licensing fee for the device and we pay a quota per year for the support."
"It has generally been very competitive. It is not the best, but it is very competitive."
"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."
"When you compare public cloud solutions to PowerEdge in terms of cost, initially the cost of Dell servers or Dell technology was really high. However, right now it's on par or, maybe, even cheaper when we use Dell hardware. If we don't swap it out in three years and if we stretch it to four or five years, then we can get even more of an ROI versus cloud cost."
"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."
"The pricing for PowerEdge servers is reasonable."
"I use it as an open-source tool."
"The pricing is low."
