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

"They are reliable, and they hardly break down; they are fast, and they serve us very well."

"When comparing the HPE ProLiant DL Servers to the HPE BladeSystem, the HPE BladeSystems are compact and need less space for installation, can provide the same computing as the HPE ProLiant DL Servers in the same unit, and are a lot easier to manage."

"We use a lot of HP products, in fact, and so HP is a big partner of ours, and it makes things in our organization run more efficiently and with less interruption when we run the BladeSystem with our other HP solutions."

"It was fantastic and we averted a crisis."

"Probably the most value there is the compactness and the density you can get into the data center."

"The solution has high performance."

"The product has been simple to set up."

"This product saved the data center space (only use 10 U Spaces for max 16 servers) and has better performance for the VMware, vCenter, and vMotion."

More HPE BladeSystem pros

"We are using Lenovo Flex System for our internal platform where we store our operating systems, Windows, Linux, and VMware, and then virtualize our machines."

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

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

"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 functionality is reliable and requires minimal support."

"I have found the solution to be quite stable."

"The Lenovo Flex System is very stable."

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."

"We would like to see faster processing and more memory."

"The scalability is limited because you only have a 16-server by chassis."

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

"The profiles need a complete rework, the way the profiles and networks are assigned to the blades isn’t user friendly and is often a hindrance."

"The servers are a little bit huge, so it would be great if they could renew the size."

"The only issue I’ve encountered has been with pre-sales support (i.e. getting accurate quotes to purchase systems)."

"If the hardware offered higher efficiency, that would be an ideal situation for our company."

More HPE BladeSystem cons

"The price of the Lenovo Flex System could improve."

"The product could improve its integration capabilities."

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

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

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

"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 user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."

"The installation was not easy."

More Lenovo Flex System cons

Pricing and Cost Advice

"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 pricing is competitive."

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

"BladeSystem is a little bit cheaper."

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

"We have an annual license."

"The chassis itself, with no blade server inside, so expensive. The C7000 model costs around $100,000."

"The product’s price is high compared to one of its competitors."

More HPE BladeSystem pricing and cost advice

"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."

"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."

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

"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."
