Centralized modular platform has improved data center management and supports mission-critical workloads
The main area for improvement I see is the training process. When you use anything, how easily it is to manage is very important in hyper-converged solutions. If you compare it with VMware, it is very familiar. HPE Converged, however, is very large to understand for a new person. I am talking about training and management perspective, and user management. A system integrator and any system engineer who will operate and manage the system should find it easy to understand any configuration part and understanding part, which is currently a little bit tough. In Virtual Connect, we need some improvement. If we are going to move to hybrid, we need to easily move VM transactions from on-premises to cloud. We require a good, more easy process for day-to-day activities. Performance-wise, HPE BladeSystem is good regarding its ability to support mission-critical applications. However, reliability is all dependent on the core and memories, which will centrally control the entire blade and hyper-converged. We require more reliable things because if something goes down in the controller and center control, it is very tough to manage. We require a centralized image that will be replicated to any other device immediately, and all configurations and everything will come as soon as possible.

Used to run the compute load on servers, but firmware and driver upgrades are a bit difficult

Quotes from Members

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

Pros

"HPE BladeSystem is a scalable solution. It is a composable infrastructure which we can manage our external services. This is the one factor which I can see the server is much more suitable for the OneView console."
"The virtual connect side of networking and the manageability through that is by far the biggest win for us."
"The solution is one of the best in terms of providing an excellent ROI to its users."
"HPE BladeSystem is very reliable, it is 100 percent stable."
"It's very scalable."
"No critical outages have occurred at a blade enclosure level in over nine years of use with c7000 generations, other than a single defective OA module."
"Single point of management, redundant management components, reliability, easiness of setup and installation."
"The density of the BladeSystem, that we can keep adding blades as we need more VMs."
"It's stable, it works well, and we have had no problem with it for a long time."
"The initial setup is straightforward."
"One of the most valuable features of this solution is its ease of use."
"The most valuable feature of the Lenovo Flex System is the storage system."
"It comes at a good price. We didn't face any problems with this product."
"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."
"The product is very user-friendly and has many resources at the enterprise level."
"We use the solution as a compute model to run the compute load on servers."
 

Cons

"A single OA replacement caused 15 servers with VPC protection to be dropped off the network when the device was failed from active to passive; completely disrupting 200+ VMs and >2000 users; all when it was assured to failover gracefully."
"Alerting management could be better."
"Creating an integrated solution could make HPE BladeSystem more appealing."
"The integration and price of HPE BladeSystem could be improved."
"Access to updated drivers and firmware. They now require you to log on and have the device serial number to get to drivers."
"It needs to have backward compatibile firmware. Also, the enclosure for Generation 9 canot be paired with Generation 1 or 6 so it takes more effort to perform the migration."
"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 would like to see OneView software features as an additional feature."
"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 of the infrastructure."
"The price of the Lenovo Flex System could improve."
"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."
"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."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"Flex System's integration with the XClarity Management System could be improved."
 

Pricing and Cost Advice

"It is not expensive, really, in this class of server products."
"There is a one-time purchase for the HPE BladeSystem."
"The HPE BladeSystem is an expensive solution."
"Their licensing program is pretty simple."
"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."
"We have an annual license."
"The licensing is on an annual basis."
"The product’s price is high compared to one of its competitors."
"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."
"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."
"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."
