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 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 has low latency and high Ops. It is an evergreen model."
"The most valuable feature of this solution is its ease of use."
"The initial setup was extremely simple and straightforward."
"The most valuable features of this solution are its ease of use and performance."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"One of the best features is the support, which is excellent."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It is easy to scale, maintain, and manage."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."
"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."
"It is a workhorse and will run even demanding workloads."
"Stable data storage platform which promotes ease of management through its multi-cloud support. Remote support provided to users to address issues is very good."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"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."
"Scalable and stable storage array."
"The product’s quality of service guarantees the performance of each workload."
"The solution offers very good reliable systems and storage for our clients."
"The value we derive from using it is greater than other alternatives like HPE and Dell."
"The price of this solution is good."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"In terms of what needs improvement, the dashboard and management could be simplified."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I would like the UI to look better."
"The product’s pricing should be improved."
"The price of Dell Unity XT could improve."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"It is missing some features, like deduplication."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"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."
"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."
"This is an expensive solution."
"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 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."
