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."It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable feature of this solution is reliability."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The solution is very straightforward to set up."
"The initial setup was extremely simple and straightforward."
"The latency is good."
"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 performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"It is simple to make an update."
"This solution is very stable."
"IBM FlashSystem is flexible, quick, and has a solid design."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"IBM FlashSystem is the best solution for storage virtualization."
"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 FlexClone feature is the solution's most valuable aspect."
"The product’s quality of service guarantees the performance of each workload."
"Scalable and stable storage array."
"We are satisfied with the stability."
"The price of this solution is good."
"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 value we derive from using it is greater than other alternatives like HPE and Dell."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's portfolio is minimal. It is expensive."
"The tool's pricing is higher than competitors."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in the pricing of the product."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The pricing needs to be more competitive."
"The array level RAID does not seem available."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"The solution should improve its pricing and the mechanism in the reduction pool."
"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."
"This is an expensive solution."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
