Centralized profiles have simplified host deployments and have reduced configuration errors
I would say a form factor could improve Cisco UCS X-Series. We are in a life cycle replacement phase, and we face a situation where we have to upgrade the hardware, but to get to the next series, you have to upgrade all of it. The chassis, the backbone components, including fabric interconnect components that provide the networking, all have to be replaced at the same time. You cannot mix and match things. So you get to a situation in your life cycle replacement that you need to upgrade, but it does not make sense economically to just buy a newer blade when the whole life cycle replacement is on the horizon, and you are forced to just replace it all top-down. I would say a form factor that is more universal and is not going to require an overall hardware refresh would be beneficial.

Quotes from Members

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

Pros

"Cisco UCS X-Series scales with the growing needs of my organization very well, as much as you need it to with no issues whatsoever, and it scales whenever we need it to."
"The features I appreciate most with Cisco UCS X-Series are profile, profile deployment, and the ability to orchestrate configurations across all of the compute."
"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."
"It's stable, it works well, and we have had no problem with it for a long time."
"One of the most valuable features of this solution is its ease of use."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The functionality is reliable and requires minimal support."
"I have found the solution to be quite stable."
"The Lenovo Flex System is very stable."
 

Cons

"We are in a life cycle replacement phase, and we face a situation where we have to upgrade the hardware, but to get to the next series, you have to upgrade all of it."
"Cisco UCS X-Series can be improved with a longer lifespan. The products go end-of-support and end-of-life quicker than I would prefer."
"The installation was not easy."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"Flex System's integration with the XClarity Management System 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 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."
"I had some difficulties with the initial setup."
"The product could improve its integration capabilities."
"The solution's firmware and driver upgrades are a bit difficult."
 

Pricing and Cost Advice

Information not available
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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 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 price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
