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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution provides good support and service."
"Dell PowerEdge C- Series has strong features including easy implementation and configuration, and it consumes less power compared to other devices."
"Using Dell PowerEdge C- Series has helped to reduce unplanned production downtime because we configure it redundantly with redundant configurations."
"Dell PowerEdge C- Series is a contemporary solution and the best solution."
"The performance is good."
"The scalability of the solution met our needs."
"I would encourage individuals who are looking for a simple and easily maintained solution to choose PowerEdge C."
"I see it is absolutely beneficial to have a return on investment after implementing Dell PowerEdge C-Series at about 20%."
"It's stable, it works well, and we have had no problem with it for a long time."
"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."
"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."
"We use the solution as a compute model to run the compute load on servers."
"The functionality is reliable and requires minimal support."
"I have found the solution to be quite stable."
"One of the most valuable features of this solution is its ease of use."
 

Cons

"The reliability needs improvement."
"The need to update the firmware and check if there is any bug in the product is one of the areas where Dell PowerEdge C falls short and needs to make improvements."
"There could be some more ports added in the future."
"It would be easier if data center management and disaster recovery were combined."
"The VxRail should be opened to allow other virtualization platforms to be used."
"I don't see the possibility of mixing LFF drives with SFF drives in a particular machine."
"The main area for improvement in Dell PowerEdge C- Series is the booting time, as when we power on, it takes time."
"They could automate or simplify it more."
"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."
"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."
"The product could improve its integration capabilities."
"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 price of the Lenovo Flex System could improve."
"Flex System's integration with the XClarity Management System could be improved."
 

Pricing and Cost Advice

"The licensing cost of PowerEdge C is very high."
"The cost depends on the configuration."
"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."
"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."
"I would rate the pricing 4 out of 10, in terms of its cost expense."
"The price of the solution is reasonable."
"Despite the slightly higher price, we prefer Dell due to the high quality of their products."
"When we talk about pricing it is the cheapest on the market that I have found."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"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."
"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 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."
