Cons

"The initial setup of Fujitsu Primergy BX400 Series was complex."
"It can have more automation."
"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."
"It is much better to use “normal” servers. The initial investment for a blade server is very high and creates dependency."
"It is much better to use “normal” servers. The initial investment for a blade server is very high and creates dependency."
"I had some difficulties with the initial setup."
"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 solution could improve by providing more integration with other platforms."
"The price of the Lenovo Flex System could improve."
"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 most valuable feature of the Lenovo Flex System is the storage system."

"The product could improve its integration capabilities."
 

Pricing and Cost Advice

"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."
"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."
