"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."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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 duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The initial setup was extremely simple and straightforward."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The solution is very easy to set up."
"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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Its initial setup process is easy."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"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."
"The solution's initial setup process is easy."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The FlexClone feature is the solution's most valuable aspect."
"The solution offers very good reliable systems and storage for our clients."
"The product’s quality of service guarantees the performance of each workload."
"We are satisfied with the stability."
"Scalable and stable storage array."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"They could add more support for file storage and different types of storage."
"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."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"The software layer has to improve."
"The tool's pricing is higher than competitors."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The features are limited."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"Improvements can be made to the product's performance."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"There could be a snapshot feature in the solution."
"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 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."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"This is an expensive solution."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
