Featured Reviews

Roberto Hung - PeerSpot reviewer
Excellent customer service enhances solar power data management
Our company operates in the energy sector and the Dell PowerEdge M serves our needs effectively. The equipment allows us to support SCADA and servers required by our customers. We do not delve much into the intricate configuration and parts specification. We ensure the equipment meets the operational requirements set by our clients.
Syed  Ibrahim - PeerSpot reviewer
Provides a high initial ceiling before upscaling is required, user-friendly and rich in resources, but has occasional stability issues
The solution should come with cloud native applications to prepare for cloud based solutions. 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 level of customer support needs to be improved. There is currently an issue with Lenovo switching out SAN switches from the chassis, which will cause problems for people who already have a set up with the SAN switch connected to the central storage. This could require an entirely different network, adding an additional cost for the user.

Quotes from Members

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

Pros

"It helps us to manage multiple chassis from a single website."
"The Integrated Lights-Out (iLO) support is notably better than that of other servers."
"Regarding technical support from Dell, I find them to be one of the best support providers in the industry right now."
"I rate Dell PowerEdge a ten out of ten as it is a great tool with perfect support."
"The biggest advantage of PowerEdge is that it is cost-effective, and its performance and infrastructure are much better than other competitors like Lenovo and HP."
"The solution integrated well."
"PowerEdge M allows me to manage all servers and blades from one admin console."
"The tool's most valuable features are high availability and scalability. Its integration is easy."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The initial setup is straightforward."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The product is very user-friendly and has many resources at the enterprise level."
"We use the solution as a compute model to run the compute load on servers."
"The functionality is reliable and requires minimal support."
"Flex System's best features are its performance and stability."
"The Lenovo Flex System is very stable."
 

Cons

"The caching is a bit weak, making the hardware non-responsive, especially on hypervisor layers like ESXi or Hyper-V."
"The set up is complex"
"There is room for improvement in scalability."
"In terms of improvement, it should also offer a hyper-converged option."
"It requires time to transition to the new generation."
"Dell support should be faster."
"I suggest adding an additional network card within the blades, specifically for connectivity."
"One area for improvement is the connectivity, specifically the backplate and switch connections."
"I had some difficulties with the initial setup."
"Flex System's integration with the XClarity Management System could be improved."
"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."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"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 solution could improve by providing more integration with other platforms."
"The product could improve its integration capabilities."
"The most valuable feature of the Lenovo Flex System is the storage system."
 

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 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."
"It was budget friendly."
"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 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."
"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 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."
