"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"It's just very easy for general block storage."
"The stability of Pure Storage is very very good."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"It upgrades in place which means we'll be using it well into the future."
"It is the SAN backbone for our company."
"We find the ease of usability and setup valuable."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"Lenovo ThinkSystem DE Series is simple to use"
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Its initial setup process is easy."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"The solution is very easy to set up."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"We are satisfied with the stability."
"The FlexClone feature is the solution's most valuable aspect."
"The product’s quality of service guarantees the performance of each workload."
"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."
"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."
"The solution offers very good reliable systems and storage for our clients."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"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."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"CIFS and SMB Shares cannot be mounted directly."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"It was not proactive communication."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"It would be useful to have structured solutions replicated to other sites."
"The solution could be more scalable, although it suits our present needs."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"There could be a snapshot feature in the solution."
"Improvements can be made to the product's performance."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Its performance could be faster."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"This is an expensive solution."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

"The licensing model needs to be revisited. It needs to be simplified."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
