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.

Quotes from Members

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

Pros

"PowerEdge servers have high CPU processing power, and the support is also good."
"Technical support has been helpful."
"The performance is good."
"I like the feature that allows for a backup and that is suitable for me."
"With the tool, we can easily upgrade and ensure compatibility between operating systems, hardwares and drivers. Among other features, the hardware also stands out because it is certified and aligns with the processor manufacturers like Intel. This enables them to offer the latest options which are not available with other suppliers."
"The security of the product is very good."
"It was not complex to deploy."
"The hybrid solution is much more stable than other products."
"The Lenovo Flex System is very stable."
"The functionality is reliable and requires minimal support."
"It comes at a good price. We didn't face any problems with this product."
"The initial setup is straightforward."
"The product is very user-friendly and has many resources at the enterprise level."
"Flex System's best features are its performance and stability."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"One of the most valuable features of this solution is its ease of use."
 

Cons

"For improvements, the iDRAC application isn't very intuitive to handle."
"Its customer service could be better."
"The VxRail should be opened to allow other virtualization platforms to be used."
"There has been an increase in quality issues."
"A feature that needs to be added is the ability for full container storage."
"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 product’s pricing could be a little cheaper."
"The current memory 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."
"The most valuable feature of the Lenovo Flex System is the storage system."
"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'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."
"The solution could improve by providing more integration with other platforms."
"The product could improve its integration capabilities."
"Flex System's integration with the XClarity Management System could be improved."
 

Pricing and Cost Advice

"The cost depends on the configuration."
"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 don't handle the financial aspects, so I don't know the exact costs, but in terms of the value it brings, it's worth it."
"The price of the solution is reasonable."
"The product costs can be high, especially for disks and other components."
"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."
"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."
"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."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
