Relied on consistent support and efficient hardware to streamline engineering test environments
Currently, it is sometimes challenging when a component gets out of fashion or is no longer available at end of life, to quickly get a drop-in replacement. I would appreciate an XE version of the server where we have some drop-in replacements lined up beforehand, and we already know how to validate them. Right now, when this happens, we have about three months to validate the new systems, and that is usually a little short notice for us. I am already happy we get the time we get. I do have something to say about customer service and support. From time to time, we need to get special licenses or extended warranties or other items, especially for end customers. I think that could be streamlined. Right now, there is a human factor in it; there is not a click and buy option. This could save Dell some time to iterate that as well. If we have a technical question, it can take a little time, especially if we are trying to reach the Dutch support line. Usually, we still get redirected to a UK representative, which is acceptable because I speak English, but some of our customers are a little less happy. It would be beneficial if there were more local technical support. All of our questions get answered usually within a day or two, which I consider pretty quick. If it is high priority or critical, it gets answered within a couple of hours.

Quotes from Members

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

Pros

"The optimization of hardware and the ability to extend the hardware are valued features."
"I chose Dell PowerEdge R-Series because of the ease of administration, the simplicity, and the continuity of administration over the years."
"One of the key reasons we integrate Dell PowerEdge Rack Servers, particularly the ID Rack model, is for its remote monitoring and administration capabilities."
"The hardware itself is pleasant to work with. The management ability, particularly the out-of-band management, seems quite nice. The ecosystem tooling is also pleasant to work with. Additionally, Dell offers good support, and the servers are reliable."
"The solution is easy to use and has good performance."
"Using PowerEdge rack servers has allowed us to use less space. Previously, we used the regular servers, but PowerEdge rack servers take up less space and are easier to handle."
"Using PowerEdge helped to reduce unplanned production downtime by 20% to 25%."
"What truly impresses me about Dell PowerEdge Rack Servers is their unwavering commitment to customer service, providing great assistance throughout the entire product lifecycle."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The open-source nature of OpenStack provides significant value."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"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."
"The solution is stable."
"The initial setup isn't too difficult."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"The documentation was plentiful and very helpful.​"
 

Cons

"In older models, for instance, Melanox adapters remain a necessity, and they have sporadically caused complications."
"The server itself is good, but sometimes, the salesperson forgets to sell us the right controller. It is related to sales. It is not related to the technical part."
"Dell PowerEdge Rack Servers could improve in clarity when specifying options; for instance, the difference between power supplies can sometimes be a little challenging to understand if you don't already know."
"Dell PowerEdge R-Series can improve on its flexibility; having more flexible options would be beneficial."
"The GUI could be improved. I primarily work with the command line, which enables you to do many things faster."
"I would like to see more information about server health and the server's state, on the front. HP has a little screen that shows server utilization, how many disks there are inside, and the power consumption. HP also shows an alert if there is a malfunction of any device inside."
"I don't know much about the new Intel CPUs, but they need to put more than two CPUs in the servers. It may be an Intel limitation, but I'm not sure."
"I haven't seen ROI from Dell PowerEdge Rack Servers."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"So for the main stability, there have been a couple of issues that I've experienced."
"It could use more examples in different languages (API use cases).​"
"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."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The line migration is a problem."
"The pricing of Rackspace is quite high in the Vietnam market."
 

Pricing and Cost Advice

"The product's pricing is not good."
"It's not a very expensive solution."
"The solution's analytics helped to decrease production downtime by at least 30%."
"I wouldn't say the solution's pricing is the best, but it's very competitive."
"They are affordable. Even during our recent procurement, the cost of Dell servers was lower than that of HPE."
"The cost structure associated with Dell PowerEdge Rack Servers presents itself as a potential point of contention for budget-conscious consumers, as it could be more strategically positioned to compete within the broader marketplace."
"This is an expensive solution."
"The pricing is very competitive."
"I use it as an open-source tool."
"The pricing is low."
