"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"The most valuable feature is its data reduction."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"The scalability is good."
"The predictive performance analytics are good."
"It gives us capacity planning."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy 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."
"The solution is very easy to set up."
"Its initial setup process is easy."
"The solution's 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."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"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."
"Scalable and stable storage array."
"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 price of this solution is good."
"Ability to cluster two storages together with HA availability."
"The FlexClone feature is the solution's most valuable aspect."
"We are satisfied with the stability."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"I would love for them to have a hyper-converged solution."
"We would like to integrate it more with our backup solutions."
"They could improve the price."
"The integration capabilities could be improved."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"Improvements can be made to the product's performance."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"There could be a snapshot feature in the solution."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"The features are limited."
"Its performance could be faster."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"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."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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."
"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."
"This is an expensive solution."
