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

"The most valuable feature of HPE BladeSystem is its upgradability and centralized configuration."
"The density of the BladeSystem, that we can keep adding blades as we need more VMs."
"The product is good and strong."
"The solution is very easy to use; it's user-friendly and simple to navigate, the space conservation it provides is excellent, it helps compact the server, the product is quite stable, its performance is reliable, and the solution can scale so a company can expand it if it wants to."
"The HPE BladeSystem is easy to manage; it is a fantastic product that datacenter managers, cloud services providers, and server room operators should embrace because it has all you could ever think of."
"The solution is simple and easy to manage."
"These are the servers I use to host my virtual desktops and virtual servers."
"The small footprint that they have, the reliability and the ease of use are key factors."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The Lenovo Flex System is very stable."
"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."
"It comes at a good price. We didn't face any problems with this product."
"The functionality is reliable and requires minimal support."
"The initial setup is straightforward."
"The most valuable feature of the Lenovo Flex System is the storage system."
 

Cons

"On very rare occasions, instability was experienced due to driver incompatibilities or firmware maladies."
"I would like to see a better UI for configuring the VDX switches."
"We had a few hard drives that crashed, and we couldn't find them locally."
"Higher bandwidth interconnects could be introduced."
"Sometimes there are scalability issues with relatively older generations."
"All around, it would be nice if the solution were cheaper."
"It's pretty scalable, but then again, it's pretty old. It's not as scalable as the Cisco Blades that we currently have, but I'm not going to knock it because of that, it's just because it's old it doesn't have all the technology that Cisco has right now."
"The only missing piece that would be great to add to this converged solution is an integrated KVM system that comes inside the blade enclosure, that will give flexible and easy access to the different nodes in less time."
"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 of the infrastructure."
"The price of the Lenovo Flex System could improve."
"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."
"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."
"Flex System's integration with the XClarity Management System could be improved."
"The product could improve its integration capabilities."
"I had some difficulties with the initial setup."
 

Pricing and Cost Advice

"The licenses for HPE BladeSystem are perpetual."
"I need to pay for the license, and it is expensive. We make yearly payments."
"The licensing is on an annual basis."
"With regards to the prices, they need to adapt to the current needs of the country."
"Its pricing was good. We selected this solution because it was within our budget. We paid just once when we bought it. We never bought any license."
"Add OneView and ILO advanced to the base product. Don’t adjust the price, but just include them."
"We have an annual license."
"The chassis itself, with no blade server inside, so expensive. The C7000 model costs around $100,000."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
"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."
