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 scalability of the solution met our needs."
"The management platform is great."
"With the tool, we can easily upgrade and ensure compatibility between operating systems, hardwares and drivers. Among other features, the hardware also stands out because it is certified and aligns with the processor manufacturers like Intel. This enables them to offer the latest options which are not available with other suppliers."
"PowerEdge C is the best server I have worked with. I like that it's user-friendly. PowerEdge C performs very well."
"Dell PowerEdge C- Series is a contemporary solution and the best solution."
"Since we changed to Dell PowerEdge C- Series, we have not encountered any downtime or hardware crash in the last two to three years, which has been very helpful for me."
"The product has high performance and no downtime."
"The best feature Dell PowerEdge C- Series offers is the speed, as it is much faster compared to other servers I have used and has positively impacted my organization as it is great and very good."
"It's stable, it works well, and we have had no problem with it for a long time."
"The most valuable feature of the Lenovo Flex System is the storage system."
"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 functionality is reliable and requires minimal support."
"The Lenovo Flex System is very stable."
"It comes at a good price. We didn't face any problems with this product."
"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."
 

Cons

"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."
"It would be better if the solution provided simplified storage and hardware with an integrated one-tier architecture."
"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."
"The current memory could be improved."
"Its customer service could be better."
"The solution’s pricing could be cheaper."
"Although Dell PowerEdge C- Series excels at high-density computing, it has major compromises that prevent it from achieving a perfect score."
"I don't see the possibility of mixing LFF drives with SFF drives in a particular machine."
"I had some difficulties with the initial setup."
"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 could improve by providing more integration with other platforms."
"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."
"The product could improve its integration capabilities."
"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."
"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."
 

Pricing and Cost Advice

"The cost depends on the configuration."
"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."
"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."
"PowerEdge C is a product that is priced at a medium range, so it is not too expensive."
"I would rate the pricing 4 out of 10, in terms of its cost expense."
"The licensing cost of PowerEdge C is very high."
"The price could be reduced."
"We are just paying the operational cost, which is not much."
"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."
"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 price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
