Featured Reviews

Naveen Radhwani - PeerSpot reviewer
Offers great performance and customization for application servers
There are a few bugs in PowerEdge C that require some configurational settings to be done with the help of a support team when we reconfigure the solution. This is one area where they can improve the performance of the server or implement some application improvements in the solution to make it easier for end users to implement properly.
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

"One of the main features that attract customers to buy their products is the great management tool and almost zero failure rate, making it easy to use."
"It's a good product. Virtualization on it is good."
"Every new version is better than the previous one."
"The security of the product is very good."
"PowerEdge servers have high CPU processing power, and the support is also good."
"The product has high performance and no downtime."
"It was not complex to deploy."
"It is a scalable platform."
"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."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The Lenovo Flex System is very stable."
"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 initial setup is straightforward."
 

Cons

"Customer service and support have been generally helpful but can be slow due to the need to navigate different specialists."
"It should be improved in terms of future expansion. We should be able to have additional free slots for future extensions in terms of memory."
"The VxRail should be opened to allow other virtualization platforms to be used."
"A feature that needs to be added is the ability for full container storage."
"There could be some more ports added in the future."
"The product’s pricing could be a little cheaper."
"HP is a little bit lower in terms of price."
"An area where the product lacks and needs to consider improvement is by allowing it to integrate with some AI tool for monitoring."
"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 most valuable feature of the Lenovo Flex System is the storage system."
"The product could improve its integration capabilities."
"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."
"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

"Despite the slightly higher price, we prefer Dell due to the high quality of their products."
"When we talk about pricing it is the cheapest on the market that I have found."
"The price could be reduced."
"PowerEdge C is very expensive, but personally, I think it's worth the price."
"I would rate the pricing 4 out of 10, in terms of its cost expense."
"The licensing cost of PowerEdge C is very high."
"PowerEdge C is a reasonably priced product, and the pricing depends on how many years you need the product. The cost also includes the support."
"PowerEdge C is a product that is priced at a medium range, so it is not too expensive."
"We are just paying the operational cost, which is not much."
"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 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."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
