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.

"I appreciate the reliability, as they perform exceptionally well and we never experience any issues with them."
"We deployed four PowerEdge C6100 when we needed to reduce the power consumption and the amount of heat generated in our data-center."
"The initial setup is not complex. It's a user-friendly tool."
"It was not complex to deploy."
"It is a scalable solution."
"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 product is very user-friendly and has many resources at the enterprise level."
"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."
"The most valuable feature of the Lenovo Flex System is the storage system."
"It comes at a good price. We didn't face any problems with this product."
 

Cons

"Dell PowerEdge C- Series can be improved in a couple of ways. While it is a powerhouse for dense and scale-out workloads, the complex I/O and component upgrades due to each server node being compressed into a narrow removable sled make parts replacement difficult."
"The price must be improved."
"Customer service and support have been generally helpful but can be slow due to the need to navigate different specialists."
"The solution’s pricing could be cheaper."
"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."
"It would be easier if data center management and disaster recovery were combined."
"Using Dell PowerEdge C- Series has not affected the overall flexibility of my operations or business."
"It does not have the same module flexibility that was present in IBM Blade. On the Blade System, I was able to choose between the Cisco module, or BMC module. Since the switch to Lenovo, I have not had the same choice of modules, only the BMC modules."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"The solution's firmware and driver upgrades are a bit difficult."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"The installation was not easy."
"I had some difficulties with the initial setup."
"The product could improve its integration capabilities."
"Flex System's integration with the XClarity Management System could be improved."
 

Pricing and Cost Advice

"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."
"When we talk about pricing it is the cheapest on the market that I have found."
"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."
"The price could be reduced."
"PowerEdge C is very expensive, but personally, I think it's worth the price."
"The product costs can be high, especially for disks and other components."
"There is a need to pay towards the annual subscription-based licensing model offered by the solution. The product is moderately priced. Price is a critical issue, and it is always good to have moderately priced solutions."
"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 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."
"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."
