Hybrid workloads have gained resilience and deliver reliable performance for critical data

The main issues are the acquisition cost, which is really high, and when it is necessary to replace parts, the cost is also a bit high. I think there are points for improvement in support as well. What was missing to reach a perfect rating is exactly the high acquisition and maintenance cost of these servers. Cost is really a sticking point. There is a relatively high cost, both for acquisition and for licensing some Dell software, such as the paid iDRAC licenses. I believe the cost, depending on how I use it and the workload I need, is worth it. However, I cannot forget that it is, in a way, an expensive solution.

This application is not working at our premises, because of some problem with the hardware itself. So although we brought it with our systems, and we used it to manage all the systems: the storage, the switches, and everything, nevertheless we have to support every part alone and enter the interface in one-by-one."

"Forced restarts due to free upgrades is an issue that needs to be resolved. We can manage this as we have high availability and redundancy, but without that it could be a real problem."

"I had some difficulties with the initial setup."

"The product could improve its integration capabilities."

"PowerEdge C is a reasonably priced product, and the pricing depends on how many years you need the product. The cost also includes the support."

More Dell PowerEdge C- Series pricing and cost advice

"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."

"The is an annual license cost to use the Lenovo Flex System. If the price was less expensive and flexible overall and for additional features, our customers would be happier."

"We are just paying the operational cost, which is not much."

"There is a one-off payment to buy the equipment and the support is purchased annually."

"The 14 blade server allows significant room for upscaling before having to invest in another chassis. You would have to purchase another chassis much sooner in the case of an eight or nine blade server."

"We have the whole maintenance for the 3 years, starting the deployment. We also have the VMware license for 3 years and I think we have another license to buy. There are no additional costs besides licensing."
