CTO at Miraj
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

"In three years, we have not had any issues with enclosures nor with server instability."
"Support is excellent and I can see a natural growth in their product."
"It was fantastic and we averted a crisis."
"I think the most valuable features that my management usually worries about are price, reliability, and its ability to be repaired and/or debugged."
"They are reliable, and it's relatively easy to manage them. They also regularly provide patching for the servers."
"The solution uses a smaller space in our data centers, uses less feeder and network cable which reduces costs, and is very easy to troubleshoot if we have issues."
"We feel it is the best fit and the most reliable product that we can use and it is a reasonable price."
"If you're looking for a solution that has near 100% uptime, these blades provide that."
"It comes at a good price. We didn't face any problems with this product."
"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 product is very user-friendly and has many resources at the enterprise level."
"One of the most valuable features of this solution is its ease of use."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"I have found the solution to be quite stable."
"The most valuable feature of the Lenovo Flex System is the storage system."
"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."
 

Cons

"It needs to be easier to help build OpenStack solutions."
"We are very happy with what we have, but HPE is not going to continue with BladeSystem. It will be discontinued so we will have to change to another product shortly."
"All around, it would be nice if the solution were cheaper."
"There are limitations in writing exploiter features because of the sanctions."
"​Storage capacity could be enhanced."
"The latest version of this system is called Synergy from HPE, and it comes with more advanced features. This is currently the most advanced solution available in the market. One of its key features is its energy efficiency, which optimizes energy usage."
"Customers are always looking for more performance, just trying to get more out of them."
"We are looking for a new product more inline with our goal."
"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 product could improve its integration capabilities."
"The price of the Lenovo Flex System could improve."
"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."
"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 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."
"The solution's firmware and driver upgrades are a bit difficult."
 

Pricing and Cost Advice

"Add OneView and ILO advanced to the base product. Don’t adjust the price, but just include them."
"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."
"The licenses for HPE BladeSystem are perpetual."
"The product’s price is high compared to one of its competitors."
"The HPE BladeSystem is an expensive solution."
"With regards to the prices, they need to adapt to the current needs of the country."
"BladeSystem is a little bit cheaper."
"We have an annual license."
"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."
"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 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."
