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.

Cons

"The initial setup of Fujitsu Primergy BX400 Series was complex."
"It can have more automation. In addition, Fujitsu should have a broader portfolio, not specifically in terms of the service solutions, but more in terms of the big picture. A broader portfolio would be nice for providing different solutions for the customers."
"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."
"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."
"Flex System's integration with the XClarity Management System could be improved."
"The solution could improve by providing more integration with other platforms."
"The product could improve its integration capabilities."
"I had some difficulties with the initial setup."
More Lenovo Flex System cons
 

Pricing and Cost Advice

"There are special licenses that are connected to the usage. We installed Fujitsu Primergy BX400 Series for a high PC solution, and for this reason, some Microsoft licenses and other special licenses were embedded or bundled to the Fujitsu solution."
"No license is required to operate the product."
"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 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."
"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."
