Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The reliability is very good."
"It simplifies storage."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"It simplifies the overall management. We don't have to worry about storage anymore."
"At this point, I don't know anything that they could provide in a better way."
"Its array houses our entire production environment."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"The FlexClone feature is the solution's most valuable aspect."
"Ability to cluster two storages together with HA availability."
"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."
"We are satisfied with the stability."
"The solution offers very good reliable systems and storage for our clients."
"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."
"The price of this solution is good."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"We have not seen a reduction in our TCO nor have we seen ROI."
"I would like to see support for NVMe, end-to-end."
"Going forward, don't complicate things for the customers."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

"The read/write ratio is an area in the solution with some flaws and needs improvement."
