Quotes from Members

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

Pros

"The most valuable feature of the solution is its stability."
"Fujitsu Primergy BX400 Series has two processors."
"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 functionality is reliable and requires minimal support."
"The Lenovo Flex System is very stable."
"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."
 

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."
"The product could improve its integration capabilities."
"Flex System's integration with the XClarity Management System could be improved."
"The solution's firmware and driver upgrades are a bit difficult."
"The most valuable feature of the Lenovo Flex System is the storage system."
"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."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"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."
"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."
 

Pricing and Cost Advice

"No license is required to operate the product."
"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."
"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."
"We are just paying the operational cost, which is not much."
"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."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
