Reliability and reasonable pricing enhance data center management

I researched on peerspot.com about IT solutions, specifically about HPE BladeSystem and HPE Synergy, because we are already using HP servers in our state data center. In HP Cloud System, we are using a converged infrastructure to connect LAN and SAN connectivity across the network. Regarding Virtual Connect technology, there is a noticeable impact on network management. For day-to-day operations, we use various applications such as Zoom and Microsoft Teams to connect virtually. Using HPE BladeSystem Virtual Connect technology in HP Cloud System, we achieve efficient network management with well-defined LAN and SAN connectivity. We already have a defined modular architecture in place designed by the HP team for our data center. My company name is National Institute for Smart Government, also called NISG, under the National e-Governance Division. My title is Technology Management Consultant. I would rate HPE BladeSystem as an eight out of ten.

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.

Quotes from Members

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

Pros

"The solution is very fast and the power consumption is great."

"Virtual Fabric and interconnects are easy to configure and maintain."

"The virtual connect and network management port is a valuable feature."

"It is a stable, dependable solution."

"The most valuable feature, of course, is its size as I can build a huge compute resource on it."

"The benefit is the density and the capability for global harmonization on the hardware, because all the hardware chassis are the same. We can also purchase the same network cards too, chassis by chassis, so it gives us a global solution."

"The feature I find most valuable is the ease of use."

More HPE BladeSystem pros

"The functionality is reliable and requires minimal support."

"It comes at a good price. We didn't face any problems with this product."

"The product is very user-friendly and has many resources at the enterprise level."

"The stability and speed are always good. The processor is good and it's still working with our loads."

"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."

"The Lenovo Flex System is very stable."

More Lenovo Flex System pros

Cons

"Really look at it closely, but really look at the Synergy product as well. That seems to me like that's the next evolution of the BladeSystem."

"We had a few hard drives that crashed, and we couldn't find them locally. We've tried internationally, but we are still struggling to get its spare parts. This is the main challenge that we have faced with this solution. Fortunately, the other drives are still working. There should be easy availability of spare parts. I should be able to request a quotation online from HPE for things that I am not able to get locally. Currently, I can order online, but when I type the serial number, most of the time, it is rejected. I don't know why it is happening. It could be because the company that sold us the system didn't buy it through the normal HPE channel. HPE should assist us as users to get the spare parts. Its security needs to be beefed up. I would like some security features. It was also challenging for us to set it up because we didn't get enough training from them."

"The connectivity speed 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."

"OA updates and upgrades have to be made simpler."

"There have been some hardware failures with them. These failures have since been solved by HPE support partners."

"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."

"Higher bandwidth interconnects could be introduced."

More HPE BladeSystem cons

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

"I had some difficulties with the initial setup."

"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."

"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."

Pricing and Cost Advice

"it would make everyone happy if the solution were less expensive."

"Add OneView and ILO advanced to the base product. Don’t adjust the price, but just include them."

"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."

"With regards to the prices, they need to adapt to the current needs of the country."

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

"The pricing is competitive."

"The licenses for HPE BladeSystem are perpetual."

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."

"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."

"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."
