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.

"The product's initial setup phase was easy."
"Dell PowerEdge C- Series is a contemporary solution and the best solution."
"We deployed four PowerEdge C6100 when we needed to reduce the power consumption and the amount of heat generated in our data-center."
"The management platform is great."
"One of the main features that attract customers to buy their products is the great management tool and almost zero failure rate, making it easy to use."
"One of the most valuable features of this solution is its ease of use."
"We use the solution as a compute model to run the compute load on servers."
"We are using Lenovo Flex System for our internal platform where we store our operating systems, Windows, Linux, and VMware, and then virtualize our machines."

"Flex System's best features are its performance and stability."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The functionality is reliable and requires minimal support."
"It comes at a good price. We didn't face any problems with this product."
 

Cons

"The price must be improved."
"For improvements, the iDRAC application isn't very intuitive to handle."
"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."
"There is no return on investment or cost reductions in the long run after implementing Dell PowerEdge C- Series."
"There has been an increase in quality issues."
"I don't see the possibility of mixing LFF drives with SFF drives in a particular machine."
"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."
"So far, the accuracy and reliability of output with Dell PowerEdge C- Series are acceptable; I find 70% satisfactory, but I still need another year to make a complete determination."
"The solution's firmware and driver upgrades are a bit difficult."
"Flex System's integration with the XClarity Management System could be improved."
"The installation was not easy."
"The solution could improve by providing more integration with other platforms."
"The product could improve its integration capabilities."
"I had some difficulties with the initial setup."
"The price of the Lenovo Flex System could improve."
"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

"The price could be reduced."
"I don't handle the financial aspects, so I don't know the exact costs, but in terms of the value it brings, it's worth it."
"PowerEdge C is a product that is priced at a medium range, so it is not too expensive."
"The price of the solution is reasonable."
"The cost depends on the configuration."
"We buy licenses for the solution's advanced features."
"PowerEdge C is very expensive, but personally, I think it's worth the price."
"When we talk about pricing it is the cheapest on the market that I have found."
"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 are just paying the operational cost, which is not much."
"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 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."
