"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."
"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."
"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 latency is good."
"The initial setup was extremely simple and straightforward."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"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."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution is very easy to set up."
"The solution's initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Its initial setup process is easy."
"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."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"The product’s quality of service guarantees the performance of each workload."
"Scalable and stable storage array."
"The value we derive from using it is greater than other alternatives like HPE and Dell."
"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 most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Ability to cluster two storages together with HA availability."
"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."
"We need better data deduplication."
"In terms of what needs improvement, the dashboard and management could be simplified."
"I'd like to see the product implement active replication for vehicles such as VMware."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"I would like to see replication and DR features in the next release of this solution."
"It would be useful to have structured solutions replicated to other sites."
"Improvements can be made to the product's performance."
"The solution could be more scalable, although it suits our present needs."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"There could be a snapshot feature in the solution."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"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."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"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."
"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."
"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."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The licensing model needs to be revisited. It needs to be simplified."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
