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."Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Technical support has been helpful and responsive."
"Overall stability is very good. It is a very stable solution."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"It has benefited my organization because it has reduced time to insights."
"It has good, reliable, fast storage."
"One of the best features is the support, which is excellent."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"We use it to implement all our VDI solutions."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."
"Dell EMC Unity XT has good integration with VMware."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"It is easy to manage. A lot of the system manages itself."
"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 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."
"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."
"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."
"Scalable and stable storage array."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"They could add more support for file storage and different types of storage."
"The tool's pricing is higher than competitors."
"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in the pricing of the product."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"I would like the UI to look better."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"I would like to see more integration with other products."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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 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."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
