Executive SummaryUpdated on Feb 3, 2025

HPE NonStop and Lenovo Flex System compete in the enterprise computing solutions market. Customers often favor HPE NonStop for its scalability and high availability. However, Lenovo Flex System is noted for broader integration capabilities and modern architecture, offering a compelling value proposition for many.

Features: HPE NonStop is recognized for its fault-tolerant systems, ensuring 24/7 uptime for mission-critical applications, along with strong workload management capabilities. It also offers linear expandability, allowing businesses to double processing power easily.

Room for Improvement: HPE NonStop can refine its integration capabilities and modernize its architecture to compete with contemporary systems.

Vice President of It Operations at a computer software company with 51-200 employees

With a perfect record for uptime, the solution ensures a return on investment

Since it is a legacy tool, there is a need to change it for flexibility. I think now it has improved because the security is very good. It is very secure for the performance of the machine critical application service, and it is very good. I don't know how to speak more on improvement needed because it's a good enough tool. However, depending on the application, it's limited. Not a lot of applications run on HPE NonStop. It is not flexible because I know that because of the compatibility of Java with HPE NonStop. When we are using Java, the performance is not good.

Provides a high initial ceiling before upscaling is required, user-friendly and rich in resources, but has occasional stability issues

The solution should come with cloud native applications to prepare for cloud based solutions. 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. The level of customer support needs to be improved. There is currently an issue with Lenovo switching out SAN switches from the chassis, which will cause problems for people who already have a set up with the SAN switch connected to the central storage. This could require an entirely different network, adding an additional cost for the user.

Cons

"It would be helpful if they brought the price down."

"HPE NonStop could improve by having infrastructure management."

"It is not flexible...Not a lot of applications run on HPE NonStop."

"The solution could improve by providing more integration with other platforms."

"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 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."

"The most valuable feature of the Lenovo Flex System is the storage system."

"The solution's firmware and driver upgrades are a bit difficult."

"The product could improve its integration capabilities."

Pricing and Cost Advice

"HPE NonStop is definitely on the higher end."

"The price of the solution is too high. If they lowered the price substantially it would open up more opportunities. It's considered a replacement for the old 9000 boxes of HP. If it had a lower price, we would be able to compete in the financial, and other sectors and other solutions such as Terraform. Having a high price makes other solutions more attractive."

"On a scale of one to ten, where one is very cheap, and ten is very expensive, I rate the pricing an eight."

"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."

"There is a one-off payment to buy the equipment and the support is purchased annually."

"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."

"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."

"We are just paying the operational cost, which is not much."
