Composable infrastructure has transformed our virtualization and has reduced costs and downtime
There are a few primary limitations and areas for improvement in Dell PowerEdge MX- Series. First, complex networking and VLAN configuration presents a challenge. Setting up Dell Smart Fabric Services can be complex for teams transitioning from traditional rack environments. Dell could improve the OpenManage Enterprise module's user interface to make advanced VLAN tagging, uplinking, and multi-chassis networking configuration more intuitive for general system administrators. The second improvement area is the high upfront cost, which is a barrier to entry. The initial capital investment for Dell PowerEdge MX- Series chassis and its corresponding high-bandwidth fabric switches is very steep. While it provides long-term return on investment at scale, Dell could improve its pricing model or offer lower-density starter configurations to make it more accessible to mid-market organizations. The last area I would like to highlight is the standards. Single-width compute sleds such as the MX760c have constrained space, limiting native high-power GPU options inside the blades. Heavy artificial intelligence workloads require specialized third-party expansion modules that take up fabric slots. Integrating dedicated, high-density PCIe Gen 5 and Gen 6 accelerator slots directly into standard-width compute blades would make it more suitable for modern generative artificial intelligence applications.

Quotes from Members

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

Pros

"It allows us to consolidate our infrastructure very efficiently, enabling us to deploy eight servers in a seven-unit density."
"The tool's most valuable features are high availability and scalability. Its integration is easy."
"PowerEdge has high functionality, especially for automation on the firmware, which allows us to receive alerts for issues."
"Dell PowerEdge MX- Series enhances my IT department's operational efficiency through several valuable features, including modularity that allows for easy scaling and good planning, and advanced networking capabilities with SmartFabric that make upgrades plug and play while it takes care of everything."
"The networking features for administration and working with the server are valuable."
"The density achieved by the M630 while maintaining good performance allowed us to cut our hardware footprint by more than half."
"The biggest advantage of Dell PowerEdge MX- Series is that its availability is very high, as we did not face any issue during these four years and the uptime was more than 99.8%, so the customer is very happy with this product."
"The Integrated Lights-Out (iLO) support is notably better than that of other servers."
"Flex System's best features are its performance and stability."
"It comes at a good price. We didn't face any problems with this product."
"One of the most valuable features of this solution is its ease of use."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The product is very user-friendly and has many resources at the enterprise level."
"The initial setup is straightforward."
"It's stable, it works well, and we have had no problem with it for a long time."
 

Cons

"The costing could be improved as it is somewhat expensive."
"One area for improvement is VLAN configuration."
"In terms of improvement, it should also offer a hyper-converged option."
"The caching is a bit weak, which can make the hardware non-responsive, especially on hypervisor layers like ESXi or Hyper-V."
"The ever-increasing boot time due to ever-increasing POST checks with every new generation makes maintenance tasks somewhat of a headache."
"The firmware updates for the product need improvement."
"Dell PowerEdge M needs to run AMD CPUs on it."
"I did not have any problem with the initial pricing or cost setup with Dell PowerEdge MX- Series, but I had some problems with ongoing maintenance and getting regular updates from Dell."
"The solution's firmware and driver upgrades are a bit difficult."
"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 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 price of the Lenovo Flex System could improve."
"Flex System's integration with the XClarity Management System could be improved."
"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 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."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"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."
"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."
"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 cost varies significantly depending on the server's configuration and can range from $10,000 to $60,000 for the same server line family."
"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."
"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."
"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."
