We performed a comparison between IBM FlashSystem and Lenovo ThinkSystem DM Series based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"The deduplication and compression rates are beyond impressive."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The technical support is very good."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"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."
"This solution is convenient, user-friendly, convenient and reliable."
"It's very easy to manage."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"IBM's technical support do excellent work."
"Virtualization of external storage, while adding cache and speed to the external storage."
"The pricing is reasonable."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"The solution offers very good reliable systems and storage for our clients."
"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 FlexClone feature is the solution's most valuable aspect."
"Ability to cluster two storages together with HA availability."
"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 price of this solution is good."
"The product’s quality of service guarantees the performance of each workload."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"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."
"They could improve the price."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"It has room for improvement in the area of stability."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"Customization features must be improved."
"I would like to see bigger modules."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"The solution is quite expensive. That's one of the downsides to using it."
"The marketing could be improved."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"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 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."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"This is an expensive solution."
