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."The high availability of the product is the most valuable feature."
"It has benefited my organization because it has reduced time to insights."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The most valuable feature of this solution is reliability."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The most valuable features of this solution are its ease of use and performance."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The most crucial feature of IBM FlashSystem is compression."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."
"The speed of the unit is its best feature. It performs very well."
"This solution is very stable."
"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."
"We are satisfied with the stability."
"Scalable and stable storage array."
"The value we derive from using it is greater than other alternatives like HPE and Dell."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The product’s quality of service guarantees the performance of each workload."
"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."
"I would like to see replication and DR features in the next release of this solution."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The UI for this solution needs to be improved."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The tool's portfolio is minimal. It is expensive."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"The tool's pricing is higher than competitors."
"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."
"In the next release having the next level of high-speed performance would be great."
"The solution's pricing is a bit high so there is room for improvement."
"It is slightly more expensive, however, it all depends on your supplier."
"Our model does not support compression or deduplication."
"GUI interface should be enhanced more as there is some issues in copy services."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"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 solution should change the licensing model and allow customers to choose features based on their requirements."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"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 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."
"This is an expensive solution."
