Centralized modular platform has improved data center management and supports mission-critical workloads
The main area for improvement I see is the training process. When you use anything, how easily it is to manage is very important in hyper-converged solutions. If you compare it with VMware, it is very familiar. HPE Converged, however, is very large to understand for a new person. I am talking about training and management perspective, and user management. A system integrator and any system engineer who will operate and manage the system should find it easy to understand any configuration part and understanding part, which is currently a little bit tough. In Virtual Connect, we need some improvement. If we are going to move to hybrid, we need to easily move VM transactions from on-premises to cloud. We require a good, more easy process for day-to-day activities. Performance-wise, HPE BladeSystem is good regarding its ability to support mission-critical applications. However, reliability is all dependent on the core and memories, which will centrally control the entire blade and hyper-converged. We require more reliable things because if something goes down in the controller and center control, it is very tough to manage. We require a centralized image that will be replicated to any other device immediately, and all configurations and everything will come as soon as possible.

Quotes from Members

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

Pros

"Our requirement is 99.9999% uptime, and that is what we have experienced from these servers."
"Technical support is good to excellent; it is a solid product with a lot of years behind it and a BIG install base."
"The most valuable features are its stability, reliability, ease of management, and high performance."
"I would recommend this solution based on the robustness of the machines."
"The tool is pretty good in terms of managing data, compiling the system, and expanding the infrastructure."
"Users with feedback in terms of workload performance have reported that a job that typically took 3 or 4 hours to run took a few minutes."
"For what we use blades for, it was, and still is, the best solution."
"The product has a lot of options for checking servers and IoT ports using artificial intelligence."
"It's stable, it works well, and we have had no problem with it for a long time."
"We are using Lenovo Flex System for our internal platform where we store our operating systems, Windows, Linux, and VMware, and then virtualize our machines."
"Flex System's best features are its performance and stability."
"We use the solution as a compute model to run the compute load on servers."
"The initial setup is straightforward."
"I'd recommend Flex System to others as it's much better than any other product we've had and advise that they use XClarity for system management."
"The Lenovo Flex System is very stable."
"One of the most valuable features of this solution is its ease of use."
 

Cons

"The solution could use better management capabilities. The interface in terms of management could be much more intuitive."
"There were stability issues in the early versions, Blades G1."
"We expected more processing power, with more CPU cores and a greater number of cores per CPU."
"I'd like to see an all-in-one packet in the future."
"It would be better if the boot time during POST would be reduced."
"In terms of improvements, I'd suggest enhancing the stability of the HPE BladeSystem, especially regarding network connectivity. We once had an issue where a system didn’t communicate with the network, and it took a while to diagnose the problem. Eventually, we discovered it was a motherboard issue, but we initially thought it was the network card. Improving the onboard administratordashboard to provide more granular insights, like clearly identifying faultycomponents, would make troubleshooting much more efficient. Aside from that, the system is superb and has been reliable."
"The solution can scale. It is a bit limited, however."
"It needs to be easier to help build OpenStack solutions."
"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 user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"The solution's firmware and driver upgrades are a bit difficult."
"Flex System's integration with the XClarity Management System could be improved."
"The product could improve its integration capabilities."
"The price of the Lenovo Flex System could improve."
"The installation was not easy."
"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."
 

Pricing and Cost Advice

"There is a one-time purchase for the HPE BladeSystem."
"The product’s price is high compared to one of its competitors."
"The prices for the HPE Virtual Connect Modules are expensive compared to other I/O Modules available."
"When you purchase HPE BladeSystem you have to pay for the support service. The first three years are covered under the warranty, and for any further support, you have to pay annually. When comparing the cost of HPE BladeSystem to other vendors, the fees are less expensive."
"It is not expensive, really, in this class of server products."
"Regarding the cost, HPE BladeSystem is not cheap. The solution and its support are costly, and there are challenges with renewal and pricing, especially in Nigeria, due to the dollar rate and FX issues. However, it is reliable. I don't have specific figures for licensing costs, as the procurement and finance departments handle them."
"Add OneView and ILO advanced to the base product. Don’t adjust the price, but just include them."
"We have an annual license."
"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."
"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 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."
