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 most valuable feature of this solution is its ease of use."
"Technical support has been helpful and responsive."
"The most valuable features of this solution are its ease of use and performance."
"The latency is good."
"The solution is scalable."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"Scalability is good."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"It has compression, which allows you to store more data than you would normally under the arrays."
"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"We are satisfied with the stability."
"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."
"Ability to cluster two storages together with HA availability."
"The solution offers very good reliable systems and storage for our clients."
"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."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"They could add more support for file storage and different types of storage."
"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."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"The only challenge I've ever had was with a Drive firmware upgrade."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"I would like the UI to look better."
"We would like to see more advanced integration capability added to this solution."
"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."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."
"The licensing model needs to be revisited. It needs to be simplified."
"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."
"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 tool's pricing is high."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"This is an expensive solution."
