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.

Quotes from Members

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

Pros

"For what we use blades for, it was, and still is, the best solution."

"I really appreciate the integrated Onboard Administrator, the iLO (Integrated Lights-Out) modular network, and the SAN Switches."

"Being modular and being able to replace parts as needed, is easy without taking systems down."

"Users with feedback in terms of workload performance have reported that a job that typically took 3 or 4 hours to run took a few minutes."

"For us, the best feature of the BladeSystems is the plug-and-play capability."

"HP is very aware of and adaptable to our market."

"I did a trade study on this, I think HP has a big offering in terms of the number of blades that they offer and the amount of blades they can fit in a chassis, so I think they're actually ahead of the game compared to IBM and Sun/Oracle, and some of the other ones I've seen with Dell."

"From my experience with HPE and the BladeSystem, I could obviously recommend it."

More HPE BladeSystem pros

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

"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."

"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 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."

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

More Lenovo Flex System pros

Cons

"With our initial purchase, we bought three chassis and maybe 15 or 20 blades. Out of that, we had probably a 20% failure rate within the first few weeks."

"They could include some embedded software for container technology."

"I would like to see lower consumption of electricity and there are some problems in our computer room regarding the cooling."

"If you compare it with Lenovo systems, the pricing is too high."

"Technical support is great, once you get to it"

"The only con I can think of with using HP ProLiant is the limited parts of the old servers."

"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."

"I’ve had some recent issues when doing hardware and simple memory upgrades. When I pull out and put back a blade, the system has a tendency to shut down random blades in the chassis."

More HPE BladeSystem cons

"The installation was not easy."

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

"I had some difficulties with the initial setup."

"The product could improve its integration capabilities."

"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."

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

More Lenovo Flex System cons

Pricing and Cost Advice

"The price of HPE BladeSystem could improve. They need to reduce the price to be able to compete better with other vendors, such as Dell."

"There is a one-time purchase for the HPE BladeSystem."

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

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

"The price could be cheaper."

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

"We have been satisfied with the price. However, there are additional costs for support."

"The price for HPE BladeSystem can vary between $100,000 to $1 million or above. The price can be high."

More HPE BladeSystem pricing and cost advice

"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 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."

"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."

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