We performed a comparison between Dell Unity XT 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 solution is scalable."
"The high availability of the product is the most valuable feature."
"The most valuable features of this solution are its ease of use and performance."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"What I really like about this program, is that it is easy to use and easy to configurate."
"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."
"We currently have two Dell EMC Unities going. One of them at our primary on-premise DR site. They communicate with each other. If we ever have to failover, it is right there and ready."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"I like how it separates the iSCSI drives from the standard shares. It has two different routes to it. I know most of the other solutions do this, but I just like the way that Dell EMC does it."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"The high availability of Dell EMC Unity XT has been the most important feature."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"We've never had an issue with storage."
"Purchasing; We worked with a sales rep to purchase our Unity."
"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."
"Ability to cluster two storages together with HA availability."
"The FlexClone feature is the solution's most valuable aspect."
"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."
"We are satisfied with the stability."
"Scalable and stable storage array."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see the concept of Storage Groups brought back to this product line."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"Licensing costs could be reduced."
"It needs more functionality and the ability to move across more landscapes."
"It is expensive, and the pricing could be better."
"The licensing model needs to be revisited. It needs to be simplified."
"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."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"The tool's pricing is high."
"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."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
