High-density servers have maximized compute efficiency and have powered critical workloads reliably
Regarding how Dell PowerEdge C- Series can be improved, I would highlight a couple of areas. While it's excellent for dense and scale-out workloads, it isn't perfect for every scenario, and the complex I/O and component upgrades pose challenges since each server node is compressed into a narrow removable sled, making physical space inside the node tight. Replacing components requires pulling the entire node out and dismantling the protective casing. PCI expansion is also limited compared to standard 2U single-node servers such as the PowerEdge R700 series, which can hold up to eight PCI slots. Dell PowerEdge C- Series typically supports only two to three slots, restricting the addition of multiple specialized network interface cards. Finally, the initial capital expenditure is heavy; acquiring a PowerEdge C chassis and its multiple sleds requires significant upfront commitment, making it less cost-efficient if you need one or two nodes now, as you generally need to commit to the ecosystem upfront.

"Technical support has been helpful."
"The solution's ease of use is its most valuable aspect for our organization, with user-friendly management, very good security, fair pricing, and useful new features added with every release."
"The best features of this solution are that it's easy to implement and manage, and I assess the balance of performance, flexibility, and scalability provided by this solution as good."
"The product stability has been excellent."
"I would encourage individuals who are looking for a simple and easily maintained solution to choose PowerEdge C."
"It's a good product. Virtualization on it is good."
"It's stable, it works well, and we have had no problem with it for a long time."
"We use the solution as a compute model to run the compute load on servers."
"The Lenovo Flex System is very stable."
"One of the most valuable features of this solution is its ease of use."
"I'd recommend Flex System to others as it's much better than any other product we've had and advise that they use XClarity for system management."
"It comes at a good price. We didn't face any problems with this product."
"Flex System's best features are its performance and stability."
"I have found the solution to be quite stable."
 

Cons

"I am uncertain about the return on investment and whether I have seen a return on investment with Dell PowerEdge C- Series."
"A feature that needs to be added is the ability for full container storage."
"There are a few bugs in PowerEdge C that require some configurational settings to be done with the help of a support team when we reconfigure the solution."
"It would be better if it worked with SMTP servers on the cloud. Right now, it only allows notifications via the SMTP server. In the next release, I would like to have a better processor."
"Using Dell PowerEdge C- Series has not affected the overall flexibility of my operations or business."
"There is some trouble with the stability part of the product, making it an area where improvements are required."
"There could be some more ports added in the future."
"Its customer service could be better."
"The user-interface needs improvement, because they have an application from which we have to manage the whole system and all the infrastructure. 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."
"I had some difficulties with the initial setup."
"Flex System's integration with the XClarity Management System could be improved."
"The product could improve its integration capabilities."
"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."
"The price of the Lenovo Flex System could improve."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
 

Pricing and Cost Advice

"When we talk about pricing it is the cheapest on the market that I have found."
"PowerEdge C is very expensive, but personally, I think it's worth the price."
"We buy licenses for the solution's advanced features."
"The licensing cost of PowerEdge C is very high."
"Despite the slightly higher price, we prefer Dell due to the high quality of their products."
"PowerEdge C is a product that is priced at a medium range, so it is not too expensive."
"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."
"I would rate the pricing 4 out of 10, in terms of its cost expense."
"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."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
"We are just paying the operational cost, which is not much."
