Fatai Akinwande

Specialist Datacenter and Server at IHS Towers

Enables you to manage all resources from a single dashboard using the OneView feature

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.

Syed Ibrahim

Assistant Manager Systems - IT Infrastructure at a transportation company with 10,001+ employees

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

"In terms of improvements, I'd suggest enhancing the stability of the HPE BladeSystem, especially regarding network connectivity.

Aside from that, the system is superb and has been reliable."

"The price of the solution has room for improvement."

"The response time in terms of getting technical support assistance could be improved."

"I would prefer to have changes in the compatibility of the blade servers with the new ones designed by HPE, as the top team's version does not have it."

"HPE has a replacement system called Synergy, though it’s a more high-end system than the old C7000."

"HPE BladeSystem could improve the communication between the server and the storage."

"The integration and price of HPE BladeSystem could be improved."

"We sometimes have compatibility issues depending on the browser that you are using. For example, sometimes you have to switch between Edge, Mozilla, Internet Explorer, or Chrome to have things operating correctly."

More HPE BladeSystem cons

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

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

"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."

"Flex System's integration with the XClarity Management System could be improved."

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

"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."

"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 product could improve its integration capabilities."

Pricing and Cost Advice

"It is not expensive, really, in this class of server products."

"I need to pay for the license, and it is expensive. We make yearly payments."

"It is expensive. There are no additional costs. We are able to get good discounts anyway from HPE, but if the price can come down, we'll be happy."

"The price could be cheaper."

"The pricing is competitive."

"I would recommend this solution for large enterprises. Medium-sized companies would find it difficult to afford the HPE BladeSystem's overall capital expenses."

"We have an annual license."

"The HPE BladeSystem is an expensive solution."

More HPE BladeSystem pricing and cost advice

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

"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."

"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."

"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."

"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."
