Quotes from Members

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

Pros

"They're easy to swap and move around the datacenter, for sure. They don't occupy too much space for what they offer."
"A single unified infrastructure that can be optimized for all workloads via software makes our life easier."
"The composability is great."
"The hyper-converged infrastructure where everything is stateless is valuable. Basically, you have your compute storage and networking management."
"The wireless mounting system is excellent. We can use the monitor over the Internet and perform troubleshooting remotely with the connection to SQL. It includes a comprehensive monitoring tool. It offers many features, allowing us to update, manage, maintain, and troubleshoot the system efficiently."
"Synergy has lowered our total cost of ownership significantly, I would say ballpark around 25 percent, maybe more."
"Because we are bringing in and deploying things very quickly, we can go to the business and give them solutions pretty quickly."
"The solution has reduced our cost of operations and has also reduced our IT infrastructure costs."
"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."
"It's stable, it works well, and we have had no problem with it for a long time."
"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."
"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."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The initial setup is straightforward."
 

Cons

"ICMs could be better in this model. When you look at its competitors, the most critical point is the throughput. HPE is the best with the ICM module, which is an interconnect module that connects the servers of the frames to the LAN and SAN. HPE Synergy should also support the latest processors provided by Intel."
"I think the main issue with Synergy is a topology that HPE defines to connecting and creating a cluster."
"The user interface could be more user-friendly. It's for admins, and you should have the knowledge to use it."
"One of the features I want to see, which I will see with OneView 5.0, is to have all the OneView consoles in a single pane of glass. That will make it easy to see everything in one place and not have to log in to multiple consoles."
"It has affected the productivity of our development team in a bad way. When we first stood the hardware up 18 months ago, the image streaming capacity and capability were not very good at all. We had hoped that it would allow us to be more composable and be able to switch over from one version of an operating system to another version of an operating system. However, it wasn't ready for prime time yet. Therefore, we had to go back to a deployment of bare metal install. We are still waiting and trying to figure out how we can do the composable infrastructure."
"That means you're managing and you're monitoring your networking, your compute, your storage from it, but not everything works."
"The post-sales activity needs improvement. There is some sort of convoluted spreadsheet that you have to fill in prior to the platform being delivered. It seems a little bit out-of-date and inefficient. Surely, there is some sort of web page configuration tool online that a customer could use. Then, it could be validated by somebody else, like a partner or HPE technical resource, then that would be a lot more efficient."
"​Because we're using 2012, we're having issues making templates."
"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."
"The solution could improve by providing more integration with other platforms."
"The installation was not easy."
"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."
"I had some difficulties with the initial setup."
"The solution's firmware and driver upgrades are a bit difficult."
"The product could improve its integration capabilities."
 

Pricing and Cost Advice

"For me, the scalability is how much money that I need to spend on switches for how many frames, which ultimately means servers. To get the best bandwidth before the most recent product announcement, I have buy new switches every three frames. The competition is shipping a product right now where I only need switches every ten frames."
"We outright purchased Synergy."
"We pay about £500 for the solution."
"The price point is a little high. We were able to get a good deal on a promotion, to go with it. It would be nice to see the prices come down a little bit."
"The solution has reduced our IT infrastructure costs because we have had to buy less services than we used to."
"We do a biannual renewal. I know how much that renewal is, but I don't know how much it breaks down to be just Synergy, since we have our VMware, all of our physical equipment, etc. all rolled up into one renewal, which is a little over $300,000 every two years. However, only a subset of that is the Synergy product."
"For temporal use, when you throw on the fact that you're essentially doubling your capacity, right there you could claim a 50 percent TCO reduction."
"Synergy has lowered our total cost of ownership significantly. I would say ballpark around 25 percent, maybe more."
"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."
"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."
"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."
