Executive SummaryUpdated on Dec 7, 2025

Dell PowerEdge MX-Series and Lenovo Flex System both cater to the enterprise server market. Dell seems to have the upper hand in terms of high-density compute solutions and advanced management tools, while Lenovo leads in user-friendliness and cost-effectiveness.

Features: Dell PowerEdge MX-Series is known for its modular design and scalability, robust virtualization capabilities, and advanced power control tools like iDRAC and OpenManage. It excels in consolidation and resource management, making it optimal for cloud environments. Lenovo Flex System offers a strong storage system and enterprise-level resources, providing high resource consumption capacity before upscaling is needed, and is praised for its stability and user-friendly interface. Its pricing metrics are also attractive.

Room for Improvement: Dell PowerEdge MX-Series could address chip creep issues and improve iDRAC access processes. Interconnectivity with third-party equipment and broader networking options are areas of potential enhancement. Lenovo Flex System needs improvement in integration capabilities and management software and could benefit from more intuitive management tools and increased module flexibility compared to IBM's offerings.

Ease of Deployment and Customer Service: Both Dell and Lenovo systems provide a satisfactory on-premises deployment experience. Dell's customer service receives mixed reviews, indicating some challenges with support consistency. Lenovo's support is generally rated highly as knowledgeable, though reliance on firmware updates can be a source of frustration for both.

Pricing and ROI: Dell PowerEdge MX-Series prices fluctuate based on configuration, necessitating negotiation but providing a solid ROI due to performance and reliability. It is more expensive due to newer technologies like PCIe 5. Lenovo Flex System offers reasonable pricing relative to its quality, with good value and significant upscaling room within its blade server, also delivering compelling ROI by leveraging cloud and virtualization advancements effectively.

Data Center Engineer And Server Administrator at a consultancy with 10,001+ employees

Reliable hardware has kept critical data center services running nonstop with minimal intervention

I wanted to highlight that sometimes the patches from the firmware are not compatible with the hardware, which can crash the operating system and mess up the RAID configuration. If the patches are corrupted from the software level, we can roll back from safe mode, but if they crash on a hardware level, the whole box goes down, and it is very difficult to get the server online. The product cost is fine, but the licensing cost is much higher. For the licensing regarding Dell storage and warranty, if they could give us some discounts for extending the warranty on a Dell part, that would be beneficial for my organization.

More Lenovo Flex System pros

Cons

"We have had some issues with the vendor's support that we have received. When you open up a support case with Dell they send a partner to assist you and in our experience, they are lacking knowledge about the solution. There are times when you need professional support from the vendor that knows the solution well."

"Dell support should be faster."

"There is room for improvement in scalability."

"More interconnections with third party equipment and limited I/O selection."

"I wanted to highlight that sometimes the patches from the firmware are not compatible with the hardware, which can crash the operating system and mess up the RAID configuration."

"The set up is complex"

"It requires time to transition to the new generation."

"Regarding firmware updates, the complexity of seeing the compatibility matrix with the operating system and all the firmware that we have to install in Dell PowerEdge MX- Series blade servers, the chassis, and switches inside is challenging."

More Dell PowerEdge MX- Series cons

"The product could improve its integration capabilities."

"The solution could improve by providing more integration with other platforms."

"The most valuable feature of the Lenovo Flex System is the storage system."

"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 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."

"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."

"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."

More Lenovo Flex System cons

Pricing and Cost Advice

"The solution's pricing is slightly higher."

"If we would not have gone with the vendor we might have been charged unnecessarily for packages we did not need."

"The pricing of PowerEdge Next is higher than it was before."

"The product is budget-friendly. The initial cost for each server was around 10,000 euros. It's a standard price, not too high or too low."

"It was budget friendly."

"I know we get three years basic, and the on-site licensing model for business seems fine. I wouldn't pay for a support plus or anything."

"The cost varies significantly depending on the server's configuration and can range from $10,000 to $60,000 for the same server line family."

"Dell PowerEdge M price is comparable to other solutions but cheaper than IBM. However, the IBM solution is a higher grade solution whereas Dell PowerEdge M is a medium-level solution."

More Dell PowerEdge MX- Series pricing and cost advice

"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 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 price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."

"We are just paying the operational cost, which is not much."

"There is a one-off payment to buy the equipment and the support is purchased annually."

"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."
