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.

With many servers in one, these blade servers are easier to manage
The service could be improved by faster servers, more widely available VMs, and more storage in one place. Then, in the event of a blade failure, we could start our VMs on another blade in a couple of minutes. This is why we wanted to buy storage. But now, we want to buy a twin server with 24 VMware discs to create test storage. The next product release should allow more servers to be controlled simultaneously.

"The solution does not scale well."

Pricing and Cost Advice

"The pricing is great; very competitive. That's the reason we bought hundreds of them."
"If price isn't a concern, I would recommend it."
"It's abundantly clear that the specific licensing requirements will be dictated by the intricacies of the machinery we deploy."
"The price is good for the quality of the Dell PowerEdge Rack Servers."
"This is an expensive solution."
"The high cost of Dell PowerEdge Rack Server licenses is attributed to the pre-installed Windows Server operating system from Microsoft."
"The pricing of Dell PowerEdge Rack Servers has been a little problematic. It was sticker shock with our most recent purchase compared to the previous one, and there's a gap in pricing at our current level because what we do isn't very compute-intensive, resulting in a mismatch where we fit into an in-between category without an exact solution available."
"We would prefer it if the pricing were for half the cost. We have been expanding our company, and my boss stated that we must save money."
"The product is not expensive."
