Featured Reviews

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.
Al Vasek - PeerSpot reviewer
Supports business apps and VDI with reliable compute
The solution is all about compute. The solutions are easy to handle, priced correctly, reliable, and dependable. Cisco is similar but more complex to configure and usually more expensive. My team supports a lot of Dell, focusing on hybrid environments like Azure Stack, splitting workloads between high compute needs in databases, which are expensive in the cloud, and other workloads in the cloud.

Quotes from Members

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

Pros

"Flex System's best features are its performance and stability."
"The product is very user-friendly and has many resources at the enterprise level."
"The Lenovo Flex System is very stable."
"It comes at a good price. We didn't face any problems with this product."
"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 most valuable feature of the Lenovo Flex System is the storage system."
"We use the solution as a compute model to run the compute load on servers."
"The product has high performance and no downtime."
"PowerEdge C is the best server I have worked with. I like that it's user-friendly. PowerEdge C performs very well."
"Technical support has been helpful."
"The security of the product is very good."
"The most significant benefits, in my experience, are the configuration, reliability of the equipment, and the support of Dell."
"PowerEdge servers have high CPU processing power, and the support is also good."
"I have found the compression capability the most valuable feature."
"The scalability of the product is good since it offers high performance and capacity."
 

Cons

"Flex System's integration with the XClarity Management System could be improved."
"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."
"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."
"The solution could improve by providing more integration with other platforms."
"I had some difficulties with the initial setup."
"The product could improve its integration capabilities."
"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 product’s cost needs improvement."
"We had a few minor issues with compatibility on the latest version during the installation process."
"The price must be improved."
"There is some trouble with the stability part of the product, making it an area where improvements are required."
"For improvements, the iDRAC application isn't very intuitive to handle."
"There could be some more ports added in the future."
"It would be better if it worked with SMTP servers on the cloud. Right now, it only allows notifications via the SMTP server. In the next release, I would like to have a better processor."
"The solution’s pricing could be cheaper."
 

Pricing and Cost Advice

"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 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."
"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."
"Despite the slightly higher price, we prefer Dell due to the high quality of their products."
"PowerEdge C is a product that is priced at a medium range, so it is not too expensive."
"The product costs can be high, especially for disks and other components."
"I would rate the pricing 4 out of 10, in terms of its cost expense."
"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 licensing cost of PowerEdge C is very high."
"The cost depends on the configuration."
"We buy licenses for the solution's advanced features."
