Modular platform has delivered flexible AI, VDI, and private cloud with higher efficiency
The biggest advantage of Dell PowerEdge MX- Series is its flexibility. The main advantage is its flexible chassis-based architecture. The biggest advantage is its composable architecture as I mentioned. I can add compute sleds without changing the storage on demand. From the point of deployment, workloads can be provisioned rapidly by using the centralized management tool. The impact on sustainability in Dell PowerEdge MX- Series involves improving energy efficiency. Dell reports substantial power efficiency across new generations, which helps reduce data center energy consumption. The iDRAC and OpenManage tools provide power monitoring and optimization features. Dell PowerEdge MX- Series uses shared power supplies that reduce hardware deduplications and improve overall resource utilization as compared to standalone servers.

Quotes from Members

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

Pros

"In my perspective, I do not have much negative feedback about Dell PowerEdge MX- Series, as the features are great."
"The good part is it's a rack-mounted modular enclosure where we get all the combination of networking, compute, management, and power, which helps in scalability as much as possible in one particular box."
"Dell PowerEdge MX- Series is highly scalable and highly stable."
"The solution offers remarkable flexibility, reliability, and extensive software support."
"The initial setup is straightforward."
"The density achieved by the M630 while maintaining good performance allowed us to cut our hardware footprint by more than half."
"Regarding technical support from Dell, I find them to be one of the best support providers in the industry right now."
"Dell PowerEdge MX- Series addresses diverse organizational needs through its versatile capabilities, handling many different workloads, functioning as traditional servers, serving as standalone servers for backup archives, and supporting customers when they need to install VDI applications, which demonstrates the comprehensive benefits the solution brings to organizations."
"The Lenovo Flex System is very stable."
"Flex System's best features are its performance and stability."
"I have found the solution to be quite stable."
"The initial setup is straightforward."
"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."
"The product is very user-friendly and has many resources at the enterprise level."
"It comes at a good price. We didn't face any problems with this product."
"We use the solution as a compute model to run the compute load on servers."
 

Cons

"I would like to see a broader range of chassis networking options."
"There is room for improvement in scalability."
"I have not noticed any specific improvements needed as most updates are done by the OEM over time."
"The last year, we experienced problems with support, as Dell decreased staff in Latin America, impacting support quality."
"One area for improvement is the connectivity, specifically the backplate and switch connections."
"Dell PowerEdge M needs to run AMD CPUs on it."
"The ever-increasing boot time due to ever-increasing POST checks with every new generation makes maintenance tasks somewhat of a headache."
"One area for improvement is VLAN configuration."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"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."
"The installation was not easy."
"The price of the Lenovo Flex System could improve."
"Flex System's integration with the XClarity Management System could be improved."
"I had some difficulties with the initial setup."
 

Pricing and Cost Advice

"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 pricing of PowerEdge Next is higher than it was before."
"It was budget friendly."
"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."
"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 cost varies significantly depending on the server's configuration and can range from $10,000 to $60,000 for the same server line family."
"If we would not have gone with the vendor we might have been charged unnecessarily for packages we did not need."
"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."
"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 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."
