Has supported future scalability with seamless deployment
In terms of potential room for improvement regarding Dell PowerEdge M, I would want to see something such as dense nodes and additional storage, as well as multiple network connectivity on the blades. The functions that I would want to see from Dell are not limited to just what I mentioned, but currently, I feel no additional features are needed. I suggest adding an additional network card within the blades, specifically for connectivity.

"The networking features for administration and working with the server are valuable."
"The most valuable feature of Dell PowerEdge M is iDRAC."
"It's great for managing overall infrastructure."
"The initial setup is straightforward."
"What I like about Dell PowerEdge MX-Series is the whole integration, where you do not have a lot of cables, which is a strong point compared to others on the market."
"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 solution integrated well."
"The functionality is reliable and requires minimal support."
"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."
"The initial setup is straightforward."
 

Cons

"Technical support is not good."
"More interconnections with third party equipment and limited I/O selection."
"Dell PowerEdge M needs to run AMD CPUs on it."
"I would like to have additional HPC and AI capabilities on general Dell PowerEdge servers."
"I suggest adding an additional network card within the blades, specifically for connectivity."
"The last year, we experienced problems with support, as Dell decreased staff in Latin America, impacting support quality."
"I believe that the tool’s support team is an area with certain concerns where improvements can be made."
"There is no specific feedback on improvements directly from our usage."
"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."
"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."
"Flex System's integration with the XClarity Management System could be improved."
"The solution's firmware and driver upgrades are a bit difficult."
"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."
"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

"It was budget friendly."
"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."
"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."
"The pricing of PowerEdge Next is higher than it was before."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"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 solution's pricing is slightly higher."
"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 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."
"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."
