Redundant components and single console management improve efficiency while high costs warrant attention
Regarding HPE Synergy, the most valuable feature is that the whole solution and the whole system operate in passive mode, and there are very few chances of downtime as all the components in HPE Synergy are redundant, including VC Flex modules and interconnect modules, as well as power supply and fan modules. Other networking and storage connectivity modules are also redundant, and we can mount the entire Synergy frame in a single rack. If we fully populate a Synergy frame with 12 servers, 12 physical machines could be mounted in one Synergy frame, mostly with redundant power supplies and networking ports along with SAN connectivity on a single console.

Quotes from Members

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

Pros

"Where it used to take one week to re-image or upgrade our hosts, it can now take one day."
"HPE is really the leading platform."
"We were able to reduce our turnaround time on some of our projects, from upwards of three or four days down to a couple of hours."
"Changing the form factor in Synergy allows us to have more RAM, which is significantly helpful for us."
"Shorter delivery times. Where we now have a delivery time of about six weeks, we hope to go back to days."
"The stability of the solution is very reliable."
"Give us the ability to seamlessly migrate from one operating environment to another within minutes, which is invaluable."
"This solution has decreased our deployment time by approximately sixty-five percent."
"The product is very user-friendly and has many resources at the enterprise level."
"It's stable, it works well, and we have had no problem with it for a long time."
"The Lenovo Flex System is very stable."
"The initial setup is straightforward."
"The most valuable feature of the Lenovo Flex System is the storage system."
"I have found the solution to be quite stable."
"One of the most valuable features of this solution is its ease of use."
"The functionality is reliable and requires minimal support."
 

Cons

"I would like to see more nodes in a single chassis so we wouldn't have to purchase additional chassis."
"The initial setup, because it was still in beta, was complex."
"HPE Synergy could improve its remote support."
"I would definitely like to see them fix the firmware updates on all the blades."
"The only issue that we had was our rack was too small. The product is heavy, so it took a lot to get it in there."
"The deployment time of a system through OneView is pretty slow, but apparently that's being addressed in an upcoming update."
"In the past, I have had issues with configurations."
"The speed in OneView and how it updates the entire configuration needs improvement. If they can do that, and it could be a little more clear on what impact different actions will have for certain things, that would be good."
"The solution could improve by providing more integration with other platforms."
"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 price of the Lenovo Flex System could improve."
"Flex System's integration with the XClarity Management System could be improved."
"The most valuable feature of the Lenovo Flex System is the storage system."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"I had some difficulties with the initial setup."
"The product could improve its integration capabilities."
 

Pricing and Cost Advice

"The Nutanix platform came in a little more expensive than the Synergy."
"The solution has reduced our IT infrastructure costs by 50 percent."
"We bought everything outright to start with. We don't do much consumption-based stuff."
"VMware is part of the cost. We bought the chassis, we bought the solution. The blades are roughly running us $60,000 a pop right now."
"The cost is high and that is a drawback for some customers."
"Synergy has lowered our total cost of ownership significantly. I would say ballpark around 25 percent, maybe more."
"When we made the purchase of the hardware, we added Professional Services to it."
"In our whole environment, the cost is in the millions. On this particular chassis, the annual cost is 12 blades times approximately $40,000."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
"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 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 are just paying the operational cost, which is not much."
